2.1 Pre–Installation Checklist
2.1.1 Site Preparation
Install the unit upright in a dry, well-ventilated, dust free environment. There must be at least
6 inches (152 mm) between the unit and the wall(s) for cooling and access to the front and
rear panels. Do not place the unit next to air conditioning or heating thermostats.
Do not connect the unit to line conditioning equipment. This can cause improper operation
of both the unit and the equipment.
Do not connect equipment that produces electrical noise such as motors, relay control
circuits, copiers or laser printers to the unit's output.
Place a warning label on the electrical panel so emergency personnel know a UPS is in the
building. Label the service panel(s) to identify the circuit(s) supplying and being supplied by
the unit.
The unit and optional battery cabinet has a combined weight of up to 1,500 lbs (682 kg).
Verify that the floor at the installation site can support at least 375 lbs / caster (170 kg /
caster) without undue stress.
2.1.2 Grounding & Utility Line
Install a hardwired ground. Since many older facilities have improper grounding, a qualified
electrician should inspect both the wiring and the grounding before installation.
Measure the line voltage at the main electrical panel. Compare that reading with the input
range as listed in the table below. The line voltage must be in within the range of input
voltages for that unit.
For information about reconfiguring the unit's input or output voltage , see Section 5.5,
"Configuring the Input/Output Voltage." For further information contact Alpha Technologies
customer service department about voltage reconfiguration.
