4.2.2. Input Connection
Please add double-pole miniature circuit breaker (equivalent UPS input breaker) to distribution
board where UPS is to be connected. Do not connect any other load to this circuit breaker and
please do not forget to add leakage current relay.
Leakage protection relay value must be the total value of 30 mA (UPS input leakage current relay)
and total leakage current value of the load connected to UPS. Relay must be protected type against
peak current that can be happened on EMI filter capacitor.
For 1Phase Input/1Phase Output FP; connect the phase cable to input “L” terminal, the neutral to
input “N” terminal.
For 3Phase Input/1Phase Output FP; connect the phase cable to input “R-S-T” terminals, the
neutral to input “N” terminal.
4.2.3. Battery Connection
If the batteries are already built-in inside the UPS cabinet; remove the cover of UPS and connect
the Positive (red) and Negative (black) cables of the batteries. There is no need any further
connection so replace the cover.
Read the Service Manual carefully for External Battery connection!
If the batteries shall be put in a separate additional battery cabinet, please follow up the
instructions below;

Connect the “PB” terminal on the external battery cabinet to battery “PB” terminal on the UPS.

Switch on to “0” position the battery cabinet circuit breaker.

Connect the “-“on the battery cabinet to “-“on the UPS.

Connect the “+“on the battery cabinet to “+“on the UPS.
The installation and adjustment of distribution panel should be done by authorized Technical
Personnel.
Swicth the circuit breaker on the distribution panel to “0” position before making the
connections.
According to EN 62040-1-2, the user should place a warning label on the input distribution
board and the other primary power isolators, in order to prevent the risk of voltage
feedback. The label should carry the following indication:
RISK OF VOLTAGE BACKFEED

Isolate Uninterruptable Power Supply before working on this circuit.

Then check for Hazardous Voltage between all terminals including the protective
