Terminal assignment
Terminal:
1 (L) and 2 (N):
Power supply connection
A control voltage is required to supply the device with power.
The unit is equipped with a multi-range power supply and may
be supplied by voltages of 100 – 240V ± 10 %, DC 50/60 Hz (see
nameplate for device voltage).
10 (L1,Lx):
13 (N,Ly):
Voltage measuring input
Input voltage both as PH-N and PH-PH measurement. Direct
measurement for 100... 500...600V AC. The measuring range is
configurable. If the measuring range is exceeded, an error mes-
sage is displayed.
For higher voltages, connection via voltage transformers is
necessary (medium voltage measurement x/100 V), measuring
range from 500V to 30.0 KV Ph-Ph.
20 (k1) and 21 (l1): Current measurement inputs
The measuring input for current must be connected via a cur-
rent transformer x/1A AC or x/5A AC.
When connecting the transformer, pay attention to the energy
flow direction and to the correct assignment of measuring volt-
age input to current transformer.
30 (C) and 31 (S):
Floating relay contact
This contact serves as a message or alarm output. During oper-
ation, an acoustic or visual message can be activated or a con-
sumer switched off using this relay. The contact is open as long
as the device is dead as well as when there is an active message.
Maximum switching capacity 2A at 250V AC.
40 (C):
Connection for voltage supply to the relay output terminals
41 to 45
The relays for the control outputs share the same
connection to the supply voltage.
