Safety

IMPORTANT SAFETY INSTRUCTIONS - SAVE THESE INSTRUCTIONS

Warning: ALL safety instructions in the Safety Sheet (990-2822) must be read, understood and followed prior to installation. Failure to do so could result in equipment damage, serious injury, or death.

Warning: Parallel operation is not available when the system is set up for 3-wire operation, which only applies to Japanese systems.

Caution: All electrical power and power control wiring must be installed by a qualified electrician, and must comply with local and national regulations for maximum power rating.

Note: The cables must be routed by the electrician but not attached. The APC Field Service Engineer will install the parallel communication box and attach all cables to the UPSs.

Note: Up to four UPS units can run in parallel.

See also:For information on UPS specifications on the Smart-UPS VT series, see part nos. (available from the document storage in the UPS):

• 990-1986 — 380/400/415 V• 990-1598 — 208/220 V• 990-2360 — 200/208 V

Parallel Communication CablesThree different ways of routing cables

Note: The enclosures in a parallel system can be kept apart, or they can be assembled with interconnection plates (SUVTOPT011 APC Smart-UPS VT Parallel Operation Baying Kit). If the enclosures are kept apart the communication cables can be run in conduits (if applicable). See Install the interconnection plates.

The routing of cables between the UPSs can be done in three different ways.

1. UPSs apart (without conduits)

2. UPSs bolted together (using interconnection plates/baying kit)

3. UPSs apart (using conduits).

Schematic overview of the PBus cables layout

Note: The cables must be routed by the electrician but not attached. The APC Field Service Engineer will attach all cables to the UPS(s) and install the parallel communication box.

Note: The PBus cables run from UPS 1 to UPS 2 to UPS 3 to UPS 4 if your configuration consists of 4 UPSs.

Note: The PBus cables are labelled PBus 1 and PBus 2.

This schematic overview shows the cable layout:

Note: If the configuration consists of only two UPSs, the terminators must be installed in UPS 2. With three UPSs the terminators must be installed in UPS 3.

System arrangements

APC recommends the following arrangements of the UPS units and the XR Battery Enclosures (XR) in parallel:

Note: UPS units and their respective XR Battery Enclosure must be bayed together. XR Battery Enclosures must never be shared in a parallel UPS system.

Interconnection PlatesNote: The enclosures in a parallel system can be kept apart, or they can be assembled with interconnection plates (SUVTOPT011 APC Smart-UPS VT Parallel Operation Baying Kit). If the enclosures are kept apart the communication cables can be run in conduits (if applicable).

Note: When enclosures are assembled with interconnection plates and bolted together, the PBus cables can be routed inside the enclosures and then only the ABus cable has to be run in a conduit (if applicable).

Note: If cables must run in conduits according to local regulations please make sure that all cables outside the UPSs are run in conduits.

Remove the front panel and the top cover

Turn the screw to the right to the unlocked position.

Lift the front panel upwards to free it from the enclosure frame.

Loosen the six screws of the top cover (four at the xxfront and two at the back).

Lift up from the back and push forward to free the xxcover.

Leave the cover unattached on top of the UPS.

Note: Remove the battery compartment cover (only applicable to Japanese systems).


Install the interconnection plates

Lift off the side panels.

Remove the batteries (see Operation manual 990-xx2282).

Note: If the UPS system is going to be anchored to the floor, drilling holes for anchoring is recommended to take place at this stage. See Anchor the UPS parallel system to the floor.

Bolt the enclosures together

Insert the front and the back xxinterconnection plates between UPS 1 xxand UPS 2 and place the two wings to xxrest on the inner panel.

Align the two enclosures and level the xxthree marked rows of bolt holes in UPS xx1 with the holes in UPS 2. Push the two xxenclosures firmly together.

1. Route the cables (UPSs apart)

Note: If the UPS system is going to be anchored to the floor, drilling holes for anchoring is recommended to take place at this stage. See Anchor the UPS Parallel System to the Floor.

Remove the front panel and the top cover. See Remove the front panel and the top cover.

Loosen the two screws from the cable-inlet plates at the bottomxplate of UPS 1 and UPS 2, and remove the plates.

From UPS 1: Route the two PBus cables to the slots on thexleft side of the enclosure and down inside the panel.

From the lowest slot fish out the cables from the side panel andxroute them down through the cable inlet and through the round hole at the bottom.

UPS 1 UPS 2
