3.4 PLACE OF INSTALLATION
3.4.1 UPS location
WARNING !
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. 104°F / 40°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.
NOTE !
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 400 & 500
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 (120Vac) should be provided near the UPS for connection of power tools,
test equipment or connectivity devices. This outlet must be grounded.

400 & 500 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
20” (500 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.
