Site Preparation Checklist
Site Requirements
Install the system on a surface that supports the weight. The input wires must reach a
suitably grounded power outlet and the load’s wires must reach the system’s output termi-
nal blocks.
Circuit Breaker
The system’s input must be connected to a dedicated utility line equipped with an appro-
priately sized circuit breaker (See Specifications). It is called the upstream circuit breaker
in this manual (See Figures 1.4.1, 1.5.1 and 1.6.1).
Mounting
There are many different types of enclosures used to house the system. They all comply
with the safety regulations for UPS’s and batteries located in an outdoor environment.
Read the instructions included with your enclosure for the safe and correct way to mount
the components. Contact Alpha Technologies’ customer service department for more
information or for technical assistance.
Backup Generator (If Used)
TIP: If the unit constantly switches between Battery and Line modes due to a noisy line, the unit’s
input parameters should be broadened from Normal to Generator.
In Generator mode, the range of acceptable input frequency and voltage is expanded to
accept the fluctuations created by a generator (Section 3.6, “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 unit to run
continuously in Battery mode.
Before installation, make sure the generator’s output voltage is compatible with the unit’s
input voltage requirements by comparing the specifications listed on both machine’s
nameplates. To make sure the system runs smoothly, use a generator that supplies twice
as much power as drawn by the total load.
