1.2 Electrical Installation

This equipment must be installed by qualified service person- nel.

Switch off IRP, IRE, IB, IUG, IBY circuit breakers to completely isolate the equipment.

Earth leakage protection: this device has high leakage current towards protective earthing. Earth leakage circuit breakers shouldn't be installed upstream from this equipment or a correct threshold should be set.

High leakage current - it is essential to connect the protective earth before connecting the power supply.

All primary power switches installed remotely from the UPS area must be fitted with the following label: "Isolate uninterruptible power supply (UPS) before working on this circuit".

General

All electrical connections must be made in accordance with local standards and all input terminals (1-L1, 1-L2, 1-L3 and, if existing, 4-L1, 4-L2, 4-L3) must be protected by external fuses. The tables give recommended values for fuse sizes and cable cross-sections. These may vary, depending on local standards. They are valid for voltages 380/220 V, 400/230 V and 415/240 V. Ensure clockwise connection of conductors L1, L2 and L3 at input and output termi- nals.

If possible, install battery cables separately from other power cables in order to avoid possible RF interference. Before wiring, open all system switches (IRP, IRE, IBY, IUG) plus the battery switch (IB).
