2.1 Site Preparation Checklist
Grounding
The UPS MUST be correctly grounded for proper operation.
Older facilities may have inadequate electrical grounding. Inspection must be performed
by a qualied electrician before installation to ensure that grounding meets the local
electrical code.
Branch Circuit Breaker Protection
To reduce the risk of re, connect to branch circuit overcurrent protection in
accordance with the National or local Electrical Code per ANSI/NFPA 70.
Disconnects
The input and output lines to and from the UPS MUST have disconnect devices
attached.
Site Requirements
Install the UPS and batteries in a restricted access location, and on a surface that supports
the total weight. The input wiring must reach a suitably grounded power outlet and the load
wiring must reach the UPS’s output terminal blocks.
Backup Generator (If used)
In Generator Mode, the UPS’s range of acceptable input frequency and voltage is
expanded to accept the uctuations created by a generator (See Section 3.4, “Operating
the UPS, Sense Type”).
Use a generator with electronic speed and voltage controls which produces less than 10%
voltage Total Harmonic Distortion (THD). Mechanical governors can force the UPS to run
continuously in Battery mode.
Before installation, make sure the generator’s output voltage is compatible with the UPS’s
input voltage requirements. To make sure the system runs smoothly, it is recommended to
use a generator that supplies twice as much power as drawn by the total load.
