Section 2Installation
IntroductionThis section explains NTDI02 termination unit installation. Do not proceed with operation until the steps are read, under-stood, and performed in the order in which they appear.
Special HandlingObserve these steps when handling electronic circuitry:
1. Use Static Shielding Bag. Keep an assembly in its static shielding bag until ready to install it in the system. Save the bag for future use.
2. Ground Bags before Opening. Before opening a bag con-taining an assembly with static sensitive devices, touch it to the equipment housing or ground to equalize charges.
3. Avoid Touching Circuitry. Handle assemblies by the edges; avoid touching the circuitry.
4. Avoid Partial Connection of Semiconductors. Verify that all devices connected to the module are properly grounded before using them.
5. Ground Test Equipment.
6. Use an Antistatic Field Service Vacuum. Remove dust from assemblies if necessary.
7. Use a Grounded Wrist Strap. Use the ABB field static kit (part number 1948385A1 - consisting of two wrist straps, ground cord assembly, alligator clip, and static dissipative work surface) when working with modules. The kit grounds a technician and the static dissipative work surface to the same ground point to prevent damage to the circuitry by electro-static discharge. Connect the wrist strap to the appropriate grounding plug on the power supply or to an unpainted por-tion of the enclosure with the alligator clip. The wrist strap must be effectively connected to the earth grounding electrode system through the AC safety ground.

Connector P1 Signal Paths
Configure a dipshunt by either cutting straps or leaving straps uncut in certain sequences. Cut the dipshunt straps using a standard shunt cutting tool. Always cut straps completely (e.g. gap should be a minimum of 0.5mm). Install the configured dipshunt into the desired socket on the termination unit. To install a dipshunt, align the end of the dipshunt identified with the silver dot to the end of the socket having an identification mark and push the dipshunt into the socket. Be careful not to bend any pins during insertion.
Connector P1 Signal PathsRefer to TB1 Through TB4 Schematics in Appendix B for detailed drawings of TB1 through TB4 and tables defining pin connections P1 to P3.
Termination Unit InstallationThe termination unit is ready for installation when the fuses are installed, jumpers are set and dipshunts are properly con-figured. The termination unit mounts on a standard NFTP01 panel as shown in Figure 1-2.

Termination Unit Installation
To install the termination unit cable:
1. Install the J2 connector of the NKTU01 or NKTU11 termi-nation unit cable in the module mounting unit backplane slot assigned to the I/O module.
2. Insert the J1 connector of the cable into P1 of the termina-tion unit.
Power Wiring
There are three terminals that provide power and ground con-nections. Refer to Figure 2-1 for terminal locations. System power connects to the termination unit through Faston con-nectors E1 and E2 and can be distributed to the configuration sockets (XU1 - XU16) through fuses (F1 and F2) and jumpers (J1 - J16). Any combination of power can be connected to these connectors depending on the application. However, this requires careful system analysis to ensure circuit board trace amperage capacity is not exceeded. A single trace can handle a continuous three amperes. System ground or neutral connects through Faston connector E3.
CAUTIONRemove a module from its assigned slot before installing or removing a cable assigned to that slot. Failure to do so could result in damage to the module.
CAUTION
Do not apply an input voltage to E1 or E2 if any of the sixteen field power inputs exceeds 120Vac. If the AC voltages are out of phase, the total voltage level will exceed the NTDI02 voltage rating which can cause damage to the termination unit.
WARNING
Verify the main power, field power, and power entry panel cir-cuit breakers/switches are turned off before starting installa-tion, retrofit, upgrade, or wiring procedures. Failure to do so could result in severe or fatal shock. Do not turn the power on until the installation, retrofit, upgrade, or wiring procedures are complete.
Startup Check List
WBPEEUI260050A0 2 - 7
To connect the power wiring:
1. If required, attach a 12-14 AWG wire from the power distri-bution source (24 VDC, 48 VDC, 125 VDC, or 120 VAC) to the E1 terminal on the termination unit.
2. If required, attach a 12-14 AWG wire from the power distri-bution source (24 VDC, 48 VDC, 125 VDC, or 120 VAC) to the E2 terminal of the termination unit.
3. If required, attach a 12-14 AWG wire from the system ground or neutral to the E3 terminal of the termination unit.
NOTE: Do not mix AC and DC power on the E1 and E2 inputs on the termina-tion unit. Do not mix AC and DC commons.
Jumper Settings
1. Position the jumper for each socket used on the termina-tion unit. Use positions 1 and 2 for E2 power and positions 2 and 3 for E1 power.
2. Since socket pairs XU7/XU8 and XU11/XU12 share a common pin on connector P1, it is important to use care when setting these jumpers. These pairs should always have identi-cal jumper settings for power.
Terminal Block Wiring
Refer to Figure 2-1 for terminal block assignments and termi-nal polarity. Field wiring requirements will depend on the application. Refer to the Site Planning instruction for specific information on field wiring installation requirements (i.e., spacing, isolation, etc.). Connect the wiring from the input devices to the terminals.
Startup Check ListThe termination unit is ready for operation when:
1. The fuses are installed.
2. The dipshunts are configured.
3. Jumpers J1 through J16 are configured.

If the printed circuit board needs minor cleaning, remove dust and residue from the printed circuit board surface using clean, dry, filtered compressed air or an antistatic field service vac-uum cleaner.
To wash the printed circuit board:
1. Clean the printed circuit board by spraying or wiping it with isopropyl alcohol (99.5% electronic grade). Use a foam-tipped swab to wipe the circuit board.
2. Remove excess solvent by using compressed air to blow it free of the circuit board.
Edge Connector Cleaning
1. Use a solvent mixture of 80% isopropyl alcohol (99.5% electronic grade) and 20% distilled water.
2. Soak a lint-free cloth with the solvent mixture.
3. Work the cloth back and forth parallel to the edge connec-tor contacts.
4. Repeat with a clean cloth that is soaked with the solvent mixture.
5. Dry the edge connector contact area by wiping with a clean lint-free cloth.
To clean tarnished or deeply stained edge connector contacts:
1. Use a nonabrasive eraser or equivalent to remove tarnish or stains. Fiberglass or nylon burnishing brushes may also be used.
2. Minimize electrostatic discharge by using the 80/20 iso-propyl alcohol/water solution during burnishing.
3. Do not use excessive force while burnishing. Use only enough force to shine the contact surface. Inspect the edge connector after cleaning to assure no loss of contact surface.

Preventive Maintenance Procedures
4. Wipe clean with a lint-free cloth.
Checking Connections
NOTE: Power to the cabinet should be off while performing this preventive maintenance task.
Check all signal wiring, power and ground connections within the cabinet to verify their integrity. When checking connec-tions, always turn a screw, nut or other fastening device in the direction to tighten only. If the connection is loose, it will be tightened. If the connection is tight, the tightening action will verify that it is secure. There must not be any motion done to loosen the connection.
1. Verify that all power connections within the cabinet are secure.
2. Verify that all wiring connections to the termination unit are secure.
WARNING
There are exposed AC and DC connections inside the cabinet. These exposed electrical connections present a shock hazard that can cause injury or death.
If input or output circuits are a shock hazard after disconnect-ing system power at the power entry panel, then the door of the cabinet containing these externally powered circuits must be marked with a warning stating that multiple power sources exist.

Section 4Repair and Replacement
IntroductionThis section explains the repair and replacement procedures for an NTDI02 termination unit. Table 4-1 is a replacement and spare parts list.
Fuse ReplacementIf a fuse opens, replace it with a fuse having an equivalent rat-ing. To replace a fuse:
1. Turn off power to the cabinet.
2. Verify that there is no power on E1 or E2.
3. Remove the blown fuse from its holder.
4. Replace the blown fuse with an equivalent fuse.
5. Turn on power to the cabinet.
Termination Unit ReplacementIf the termination unit is faulty, replace it with a new one. Do not try to repair the unit. Replacing components of a termina-tion unit may affect performance and certification. Refer to
Table 4-1. Parts List

Termination Unit Replacement
Special Handling in Section 2 when replacing a termination unit.
NOTE: Turn off power to the field devices before removing the cables from the termination unit.
Follow Steps 1 through 14 to replace the termination unit.
1. Turn off power to the cabinet.
2. Disconnect the power source and ground wiring from the E1, E2, and E3 Faston connectors of the termination unit. Mark the wires according to their terminal assignment as they are removed.
3. If the termination unit is connected to an I/O module, pull the I/O module out of its cable connection on the module mounting unit backplane.
4. If there is a termination cable connected, disconnect it from the P1 connector on the termination unit.
5. Turn off power to the field devices. Disconnect I/O wiring from the terminal blocks. Mark the wires according to their terminal assignment.
6. When all cables and wires are removed from the termina-tion unit, remove the two mounting screws and remove the ter-mination unit from the field termination panel.
7. Verify the proper fuses are installed in fuse holders F1 and F2 of the replacement termination unit.
8. Verify that the dipshunt settings and jumper settings on the replacement termination unit are the same as the dipshunt settings and jumper settings on the faulty termina-tion unit.
NOTE: NTDI01 and NTDI02 may not be interchangeable. The settings may not be the same.
9. Secure the replacement termination unit circuit board to the field termination panel with the two mounting screws.
CAUTIONRemove a module from its assigned slot before installing or removing a cable assigned to that slot. Failure to do so could result in damage to the module.
Termination Unit Replacement
WBPEEUI260050A0 4 - 3
10. Connect the termination unit cables to their assigned con-nector on the termination unit.
11. Connect the I/O wiring to the terminal strips.
12. Connect the power source and ground wiring to the E1, E2, and E3 Faston connectors of the termination unit.
13. Push on the faceplate of the I/O module to fully insert it into its module mounting unit slot. The I/O modules should be seated in the termination unit cable at the rear of the module mounting unit when fully inserted.
14. After all cables and wiring have been replaced, return power to the field devices.
15. Return power to the cabinet.
16. Check I/O points for good quality to ensure the new termi-nation unit is functioning properly.
