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).
