2. Installation
This type of connection must be carried out by qualified electrical personnel.
Before carrying out any connections, check that the battery circuit breaker is OFF
and that the upstream protection devices ( AC-power source) are open (OFF).
The overall cable diameter and the cross-sectional area
of the three wires depends on the UPS rating.
1. Remove the terminal-block cover .
2. Remove the cable entry knockouts from the cover.
3. Loosen the cable clamp .
4. Insert the cable supplying the equipment and the power cable
through the terminal-block cover .
Always connect the earthing wire first.
5. Connect the three wires of the equipment cable to the output
terminal block .
6. Connect the three wires of the power cable to the input
terminal block .
7. Tighten the cable clamp .
8. Refit and secure the terminal-block cover .
