1 Safety notes

DANGER: Risk of electric shocks, burns or explosions The "attention symbol" on the device label means:

Read the installation note in its entirety. Follow the installation note to avoid impairing the intended protection.

Only qualified specialist personnel may install, start up, and operate the device. Observe the national safety and accident prevention regulations.

When working on the device, always disconnect it from the power supply. Short circuit the secondary side of each current transformer.

Use an appropriate voltage measuring device to ensure that no voltage is present. Mount all equipment, doors, and covers before switching on the device again. Installation should be carried out following the instructions provided in the operating

instructions. Access to circuits within the device is not permitted. The device does not require maintenance. Repairs may only be carried out by the

manufacturer.Non-compliance with these safety precautions can result in serious injury.

NOTE: Risk of damage to the device Provide a switch/circuit breaker close to a device, which is labeled as the

disconnecting device for this device. Provide overcurrent protection (I 16 A) in the installation. Observe the maximum permissible values for the device supply (400 V AC/

350 V DC), mains frequency (50/60 Hz), maximum voltage at connection terminal blocks (500 V AC phase/phase or 289 V AC phase/neutral conductor).

4.4 InstallationThe device is designed for connection to various network types in two, three or four-wire networks with even or uneven load.

4.4.1 External current transformersWhen selecting the current transformer, the secondary nominal current must be 5 A. The primary nominal current is determined by the current consumption of the load. Appropriate PACT current transformers can be found in the Phoenix Contact INTERFACE catalog.

When measuring by means of current transformers, the accuracy is greatly influenced by the quality of the transformers used.Operation using voltage transducers is not supported.104414_en_00

4.4.2 Three-phase network with asymmetrical load (4NBL)

Figure 4-4 Three-phase network with asymmetrical load (4NBL)

DANGER: Risk of electric shockOnly install current transformers and corresponding measuring devices when the power supply is disconnected.Observe the order in which the current transformers are connected when wiring them (direction of current flow). Primary circuit: K-P1 L-P2; secondary circuit: k-S1 I-S2When the current transformer is operated with an open secondary circuit, hazardous voltages may occur at the secondary terminal blocks.Do not ground the secondary side of a current transformer in an IT network.

Function test

104414_en_00

7 Function test

The following errors are displayed by the EEM-MA400:

To perform the function test, the device must be connected and ready for operation. The power factor (PF) of the system must be between 0.6 > PF < 1. If the power factor

is not within this range, this function cannot be used. The connections (without neutral conductors) are checked using the

4BL/3BL/2BL/1BL setting. All connections (with neutral conductors) are checked using the 4NBL and 3NBL

setting.

Error DescriptionPHOENIX CONTACT 7-1

To eliminate Err 1, Err 2, and Err 3, change the order of the current connections. To eliminate Err 4, Err 5, and Err 6, change the order of the voltage connections of the measuring transducer.

Communication module

104414_en_00

9 Communication module

9.1 MODBUS basicsThe data is transmitted using the MODBUS RTU (remote terminal unit) protocol. Communication takes place according to the master/slave access method. Communication begins when requested by the master (PLC). Each slave (EEM-MA400) has a unique address (valid range 1 ... 247). If a slave detects that its address has been addressed by the master, the slave always sends a response. The slaves never communicate with each other. They are not able to initiate communication with the master. Connected extension modules write the analog/digital input and output values to an internal register, for example.The MODBUS master (PLC) can read the individual registers using the PLC address.The data to be transmitted is always in a fixed frame and is defined as follows:

- E.g., from the slave: Content of the requested parametersCRC (Cyclic Re-dundancy Check)

The cyclic redundancy check: test value for data in order to detect errors in data transmission.

The maximum waiting time (timeout) is 250 ms.Each bus device must have a unique address. Slave address 0 is reserved for a broadcast.
