3.4PLACE OF INSTALLATION

3.4.1UPS 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.

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.
