KEOR T
Installation Manual
Double check the polarity of battery connection!
Make sure that all circuit breakers are at “OFF” position before
starting with the installation.
Connect the phase cable to X2 OUTPUT: X2/L1 –
X2/L2 – X2/L3 terminal and the neutral cable to
X2 OUTPUT: X2/N terminal. Neutral connection
should be done directly.
To enable the short circuit protection feature of the UPS, each load should be supplied
through a separate circuit breaker chosen according to the load current. This may pro-
vide quick disconnection of the short circuited load and maintain operation continuity
of the other loads.
Each load should be supplied through separate circuit breaker and the cable cross
section should be chosen according to the load current value.
Make sure that the UPS is not overloaded to provide a higher quality supply to the
loads.
