Wiring procedure
The power cable terminals are located in the back of the UPS unit. The service personnel is responsible for the correct electrical installation. They must be authorised by the manufacturer.
The installation procedure:
1.Remove the cover(s) of the terminal box of the power cables with a screwdriver. Refer to the dimensional drawing for the correct location at the back of the unit.
2.Slide the cables through the grommets of the connection box.
3.Connect the conductors of the rectifier and bypass input cables to the proper terminals. With single phase unit it is recommended to use the same phases for rectifier and bypass inputs.
4.Connect the conductors of the load cable to the proper terminals.
5.Connect the conductors of an external battery cabinet cable to the external battery +, - and PE terminals. Check for the correct polarity.
See External Battery Cabinet (EBC) installation procedure.
Warning!
If available, the internal battery has to be disconnected first because the external battery terminals are hazardous due to the parallel battery string.
6.Secure the cables with the grommets in the connection box.
7.Fasten the cover of the terminal box with a screwdriver.
The IEC/EN
“ISOLATE UNINTERRUBTIBLE POWER SUPPLY (UPS) BEFORE WORKING ON THIS CIRCUIT.”
A readily accessible disconnect device shall be incorporated in the building installation wiring as shown in diagrams.
