11 2 Installation
Alpha Technologies
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 same circuit as quieter or more sensitive devices.
The unit cannot fully protect this type of equipment when noisy devices are connected.
Electrically noisy equipment should be connected to a dedicated unit.
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.
2.1.2 Grounding & Utility Line
All wiring should be done only by qualified personnel and comply with the local electrical
code.
The unit’s input and output voltage is factory configured to your specifications. If you need to
change either one or both, see Section 5.5, “Configuring the Input/Output Voltage.”
If required, 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
rating of the unit as listed on the nameplate label on the back panel:
•240 VAC units: the voltage must be between 216 VAC and 252 VAC.
•230 VAC units: the voltage must be between 207 VAC and 242 VAC.
•208 VAC units: the voltage must be between 188 VAC and 216 VAC.
•120 VAC units: the voltage must be between 110 VAC and 125 VAC.
Also see Section 2.8, “Transformer Output Load Sharing.”

2 Installation 12
Alpha Technologies
The unit should be wired to dedicated circuit equipped with a properly sized circuit breaker.
The breaker’s size is the unit’s maximum input current (as given in the specifications) plus
25%.
For example if the unit draws 32.0 Amps of current at 208 VAC, adding 25% the input
current becomes 40.0 Amps. A 40 Amp circuit breaker would be OK. Always follow the
local electrical code when installing or sizing circuit breakers.
2.1.3 Standby Generator
The unit has frequency sense circuits for operation with most standby generators. Use a
generator equipped with electronic speed and voltage controls since the unstable frequen-
cies created by a mechanical governor can make the unit run continuously in line failure
mode, draining the batteries.
Before installation see that the generator’s output voltage meets the unit’s input voltage
requirements as shown on both nameplates. A 240 VAC unit must be attached to a 240
VAC generator.
