2 INSTALLATION AND COMMISSIONING

NOTE: These are general installation procedures and methods. Because each site is different, consider
the site conditions and requirements when planning and conducting the installation.

2.1 Pre-installation Preparation

Before beginning the installation, consider the environmental requirements, service clearances, and
external protective devices when planning the final location of the UPS system.

2.1.1 Environment of Installation Area

Install the UPS in a clean, well-ventilated environment with the ambient temperature within the
specifications listed in Specifications on page 53.

Internal fans provide forced-air cooling for the UPS. Cooling air enters through the front panel and hot air
is exhausted through the back. Per National Electric Code, at least 3 ft. (914 mm) clearance in the front
and rear of the UPS is required for installation and maintenance, see Figure 2.1 on the next page. No side
clearance is required. During operation, only 8 in. (203 mm) rear clearance is required. Maintain at least 8
