•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)
•Make sure the unit is pre-configured as you need: single input or dual input feed (see Figure 12).
Factory standard is dual input feed, single feed is optional and if ordered with the units it comes
pre-assembled. To convert single feed into dual or vice-versa go to subsection 4.4.1.
•All 4x switches (IA1 Maintenance Bypass – IA2 Output Isolator – IA3 Bypass Input – IA4 Rectifier
Input) 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.
The wiring must be done in the following order:
1. Connect first the PE wire coming from the LV Distribution Board (mains) to the terminal "PE".
2. Connect the input wires
3-phases + N
coming from the LV Distribution Board (mains). Keep the
phase rotation in clock-wise sense. In case of dual input with 2xN wires, the 2xN have to be at the
same potential, ideally they have to be joined together somewhere upstream the UPS. Dual input
feed with just 1xN is also possible.
3. Connect the output wires
3-phases + N
. N at the output is not mandatory (depends on the type
of load).
4. Connect the battery wires, make sure the polarity (+) and (-) are correct.
Make sure you are using the recommended tightening torque (Table 7) and you are connecting each
wire at the correct terminal, on the unit itself each terminal is labelled, as shown here below in Figure
13.

4.4.1 Conversion from single input feed to dual input feed and vice-versa
The Figure 14 below shows the situation with single input feed which is achieved thank to 3x link wires
which are factory mounted in case the unit is ordered with single input feed.
To convert the unit from single into dual input feed
simply remove the 3x link wires which connect
the INPOUT RECTIFIER 1-L1, 1-L2, 1-L3 with the INPUT BYPASS 2-L1, 2-L2, 2-L3. All link wires have
M8 ending.
To convert the unit from dual into single input feed
first you need to have the 3x link wires (for PW33
60-80kW Art. 04-3820) (for PW33 100-120kW Art. 04-3822) then connect the INPOUT RECTIFIER 1-
L1, 1-L2, 1-L3 with the INPUT BYPASS 2-L1, 2-L2, 2-L3. All link wires have M8 ending, apply a
tightening torque of 12.3 Nm.
