4.3.3 AC Wiring instructions
Before proceeding to wire the UPS, make sure that you have read and understood the chapter above 4.2
Electrical installation and make sure that the following is respected:
•The cable sections and fuse ratings are respecting the local standards. Alternatively, you can use the
recommended cable sections and fuse rating in the tables 7 and 9, which are according to (IEC 60950-1).
•No mains voltage is present on the wires
•All Loads are shut down and disconnected
•UPS is shut down and voltage-free (no battery is connected)
•All modules are correctly inserted and bolded on the frame
•The maintenance bypass switch IA1 (if present) is in position OFF (open)
•All 5xparallel isolators IA2-1, IA2-2, IA2-3, IA2-4, IA2-5 are in position OFF
•Mains voltage (Input Voltage) and frequency (Input Freq.)correspond to the values indicated on the type
plate of the UPS. The type plate (Figure 1) is on the inside part of the door in a center position.
•Make sure that the total power of the load is equal or lower than the rated power of the UPS (Output
power) indicated on the type plate of the UPS.
•PE wiring is performed in accordance with the prescribed IEC Standards or with local regulations;
•UPS is connected to the mains through a Low Voltage (LV)-Distribution Board with a separate mains line
(protected with a circuit breaker or fuse) for the UPS.
•A torque wrench is used to tighten the cables, the recommended torque is indicated in tables 7 and 9.

The AC wiring must be done in the following order:
1. Connect first the PE wire coming from the LV Distribution Board (mains) to the terminal labelled "PE".
(for simplicity only the bottom cable entry is shown here, the bars for top entry are positioned the
same but mirrored bottom-top)
Bottom cable entry Top cable entry
2. SINGLE INPUT FEED - Connect the input wires 3-phases + N coming from the LV Distribution Board
(mains), by referring to the table here below. Keep the phase rotation in clock-wise sense.
