Pre power Checks

WARNING
The UPS must be commissioned by a suitably qualified, and manufacturer approved en
gineer.
Failure to ensure proper commissioning may invalidate any implied warranty.
WARNING
During the commissioning procedure the UPS output terminals will become live.
If any load equipment is connected to the UPS output terminals, fully isolate it from the UPS
to ensure that no damage is caused in the extremely unlikely event of a UPS failure
WARNING
During the commissioning procedure it may be necessary to power up the unit with the side
or top covers removed, in this situation exposure to potentially lethal voltages is possible
even with the input utility supply switched off.
Take great care at all times to minimise the risk of contact with live voltages, especially when
working around the battery or the dc busbar.

Validating the Installation

Before carrying out the following checks, refer to the `Installation Manual' supplied with the equipment
or the information contained in Chapter installation in this manual.

3.2.1 - Positioning

3.2.2 - Preliminary checks

Note: If a split bypass is fitted, apply bypass mains voltage to the bypass
3x3 UPS Commissioning
Issue 2 - November 2001
1. Check that the UPS has been correctly positioned with at least 150mm clear space at the
rear.
2. Check that there is sufficient space at the sides of the unit to gain access.
If no access is available the UPS input and output cabling must be of sufficient length to
allow the unit to be moved forward.
1. Ensure that all the UPS isolators, including he fused battery switch, are open (i.e. OFF or in
position `0').
2. Check the voltage of the input mains supply.
3. Check that the cable connections to the distribution terminal block are correct. Refer to
Figure 2 1 on page 2
4. Check that the internal battery connections are secure and any external battery connected to
the Ext.Battery Input terminals are connected in the correct polarity. Refer to the
Installation' procedure on page 2
Input mains voltage checks
1. Apply mains voltage to input terminals 14 (U1), 15 (V1), 16 (W1) & 17 (N1).
Measure line to line voltage of all three phases and ensure that the values are within ±10% of

nominal rating.
3. Ensure correct phase rotation clockwise R, S, T using an oscilloscope or phase rotation
meter
terminals 10 (U3), 11 (V3), 12 (W3) & 13 (N3) and duplicate the check for
the Input Mains.
