Terminal:
1 (L) and 2 (N):
Power supply connection
A control voltage is required to supply the device with pow-
er . The unit is equipped with a multi-range power supply and
may be supplied by voltages 100V – 240V+/ -10% 50Hz/60
Hz (see nameplate for device voltage) .
Terminal:
10 (L1)
11 (L2)
12 (L3)
13 (N):
Voltage measuring input
Input voltage both as PH-N and PH-PH measurement .
3-phase or single-phase measurement for 25 . . . 230 . . .280V
AC PH-N, 50/60 Hz . The measuring range is configurable . For
higher voltages, connection via voltage transformers is nec-
essary (medium voltage measurement x/100 V), measuring
range from 500V to 30 .0 KV Ph-Ph .
20 (k1) and 21 (l1)
22 (k2) and 23 (l2)
24 (k3) and 25 (l3):
Current measurement inputs
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 the correct assignment of measuring voltage inputs to
the current transformers .
30 and 31:
Floating relay contact
The contact serves as switching output for the fan control .
Maximum switching capacity 2A at 250V AC .
32 and 33:
Floating relay contact
This contact serves as a message or alarm output . During
operation, an acoustic or visual message can be activated or
a consumer 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 .
