2.3.1 Wiring Preparation

Removing the Cover Plates

On the back 

of the UPS, 

cover plates 

are over the 

input and 

output 

terminals, as 

shown at 

right. Keep 

screws and 

plates to one 

side.

Customer-Provided Overcurrent Protection

A branch rated overcurrent protection device (cir-

cuit breaker or fused disconnect switch) must be 

installed for the AC input.
If the start-up is on bypass, the UPS has a six-

cycle inrush current that is up to 20 times the 

rated output current. This must be taken into 

account when selecting the overload protection 

device at the AC input supply distribution point. 

To avoid random tripping on start-up, it is recom-

mended that the AC input supply be protected 

with a circuit breaker capable of withstanding 

this initial inrush.
This UPS is fitted with EMI suppression filters. 

Earth leakage current is less than 40mA. Tran-

sient and steady state earth leakage currents may 

occur when starting the equipment. This should 

be taken into account when selecting ground cur-

rent detection devices, as the earth leakage cur-

rents of both the UPS and load will be carried.
Input and output cables must be run in separate 

conduits.

!

WARNING

Please read this section thoroughly 

before attempting to install wiring to 

this unit.
This UPS should be installed by a 

qualified / certified electrician.
