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 ran-
ge is configurable. Exceeding the measuring interval results
in an error message.
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):
Measuring input for current
The measuring input for current must be connected via a current
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 volta-
ge input to current transformer.
30 (C) and 31 (S):
Floating relay contact
This contact serves as a message or alarm output. During
operation, an audible or visual message may be activated or a
consumer switched off. 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.
