3.4 PLACE OF INSTALLATION
3.4.1 UPS location
A qualified electrical contractor must carry out the installation and cabling
of the UPS.
If optional cabinets and accessories are included with the UPS, please
refer to those accompanying manuals for installation and operating
instructions.
It is important to have a clean, dust-free environment provided with proper ventilation and air-
conditioning to keep the ambient temperature within the specified operating range.
The recommended air inlet temperature is from 68°F (20°C) to 77°F (25°C) (max. 95°F /
35°C). Refer to section 3.5.
Check for sufficient floor load capacity before installing the UPS and the Battery.
Refer to section 3.1.1.
For Battery installation follow the local codes and the recommendation of the battery
supplier.
Temperature is very important for valve-regulated batteries (maintenance
free).
Operation at temperatures higher than 77°F (25°C) will reduce battery life.
The
SG Series
UPS can radiate radio frequency energy.
Although some RFI filtering is inherent to the UPS there is no guarantee that the UPS will not
influence sensitive devices such as cameras and monitors that are positioned close by.
If interference is expected, the UPS should be moved away from the sensitive equipment.
A single-phase power outlet (120 VAC) should be provided near the UPS for connection of
power tools, test equipment or connectivity devices. This outlet must be grounded.

16" / 400mm
Fig. 3.4.1-1 SG Series 225 and 300 kVA clearances
The rear panel of the UPS may be mounted
flush to a wall or other structure.
Clearance around the front of the unit should
be sufficient to enable free passage of
personnel with the doors fully open, and to
allow sufficient airflow to the door vents.
Check section 110-26(A) of the NEC code
for specific requirements.
Recommended minimum clearance between
ceiling and top of the UPS should be 16”
(400 mm
) for proper cooling air exhaust.
In case of additional cabinets (external
Batteries or input, output transformers) these
can be placed on either side of the cabinet.
