11.5 Electrical Connection
NOTE
i
i
Always connect the grounding at the device to the terminal for the protective phase grounding (terminal
block H).
Terminals and Conductors
The device has the following terminal blocks:
Terminal Block
Terminals for supply voltage (H), inputs for current measurement (E), inputs for voltage measurement (F),
binary inputs (U), and binary outputs (G):
•
Conductor cross-section, rigid max.: 2.5 mm
•
Conductor cross-section (conductor with ferrule): 1.5 mm
•
Conductor cross-section (conductor with ferrule, terminal F): 2.5 mm
•
Tightening torque: 0.4 Nm to 0.5 Nm (3.5 in-lb to 4.5 in-lb)
•
RS485 interface (J) on the terminal side: RS485 cable with 9-pole D-sub socket
•
Ethernet interface (Z) on the top side: Ethernet patch cable or crossover cable
