E50417-H1040-C568-A1, Edition 03.2015
Connect the cables of the supply voltage on the terminal side of the device at terminal block H as follows:
Supply from the Alternating Voltage System
Terminal N/-: Neutral conductor of the supply voltage
Terminal L/+: Phase of the supply voltage
Terminal : Protective grounding terminal
Supply from a Direct Voltage Source
Terminal N/-: Negative supply voltage
Terminal L/+: Positive supply voltage
Terminal : Protective grounding terminal
Terminals
Terminals for supply voltage (H), inputs for current measurement (E), inputs for voltage measurement (F), bi-
nary outputs (G) on the terminal side:
Conductor cross-section, rigid max. 2.5 mm² (AWG 14)
Conductor cross-section (conductor with ferrule) 1.5 mm² (AWG 16)
Conductor cross-section (conductor with ferrule, terminal F) 2.5 mm² (AWG 14)
Tightening torque 0.4 Nm to 0.5 Nm (3.5 in-lb to 4.5 in-lb)
Ethernet interface (Z) on the top side: Ethernet patch cable or crossover cable
Voltage measuring inputs: In the case of a direct connection and transformer connection , the device has
to be safeguarded with a listed 10 A backup fuse or a listed 10 A miniature circuit breaker. When using voltage
transformers, their secondary connections must never be short-circuited!
