4.2.1.5. Output Connection
Please add three-pole circuit breaker (equivalent to UPS output breaker) to distribution panel where
the loads are to be connected. Connect the phase cable to Output L1-L2-L3 terminal and the neutral
cable to Output N terminal. Neutral connection should be done directly.
Danger of explosion and fire if the batteries of the wrong type are used.
The batteries must be charged min. 10 hours before first-use.
Battery fast fuses should be replaced with fuses of the same type and rating.
To enable the short circuit protection feature of the UPS, each load shall be supplied
through
a separate circuit breaker chosen according to the load current. This may provide
quick
disconnection of the short circuited load and maintain operation continuity of the
other
loads. To obtain maximum protection, the rating of each individual load circuit
breaker shall
have the minimum value, which is enough to carry the full load current continuously.
Make sure that all circuit breakers are at “0” position before starting with the
installation.
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.
