The KEOR T EVO is provided with voltage
free contacts
which can be used to operate the
shunt trip
coil of
external switching device. The external device is not part of the UPS, is provided
and installed at
customer care.
In case of backfeed failure detected by the UPS, the UPS will send signal to trip the MCCB to isolate
the UPS in order to protect the upstream distribution circuits.
The installer shall apply the following warning label on all primary power isolator that supplies the
UPS.
The following tables shows the
MCCB
and shunt trip coil
specifications.
X9/e:
Neutral for mccb shunt trip signal
X9/f :
220-240 Vac will be applied for 1 second if backfeed detected.
This terminal is protected with
an internal 2A fuse.
