The UPS unit has the following power connections:

Three-phase(L1, L2, L3) and protective earth (PE) connection for the rectifier input or

Single-phase(L1), Neutral (N) isolated connection point (bypass N is used in the rectifier) and protective earth (PE) connection for the rectifier input.

Single-phase (L1), Neutral (N) and protective earth (PE) connection for the bypass input

Single-phase(L1), Neutral (N) and protective earth (PE) connection for the load output

Plus (+), minus (-) and protective earth (PE) connection for the external batteries

Note!

The rectifier requires a Neutral to operate. It’s connected internally from the bypass terminal to the rectifier, see wiring diagram.

Power cables and protective fuses

Always use copper cable types to fit terminals with approximately 1.5 Nm torque for different load currents. The Cu cable sizing is based on multi-core cables laid in conduits/trunkings on the wall or on the floor (installation procedure C), ambient temperature 25°C, PVC insulation, surface temperature up to 70°C. Cables of several UPS can be installed in parallel to each other.

Standards SFS 6000-5-52 (2002) and IEC 60364-5-52 (2001-08) “Electrical installations of buildings” are used as a sizing guide. For any other conditions, size the cables according to the local safety regulations regarding installation environment, appropriate voltage and currents of the UPS.

Fuses are sized according to local safety regulations, appropriate input voltage and the rated current of the UPS. Therefore, protect the input and bypass cables with gG (gL) fuses or B-C-D type of circuit breakers against overload and short-circuit.
