4.0 Installation

4.6 Installation procedures

Note: Except as described below for installing the 3000 VA model with the supplied

mains lead, UPS input power connections must be made by qualified service person-

nel.

The UPS may be connected to input power with either the included materials or

through a hard wired approach (see section 4.7 below).

The 3000 VA model is equipped with an IEC 320 C20 type input power receptacle, a

mains lead with a CEE7/7 type plug, and a knock out plate for hard wired installa-

tion. The 5000 VA model is supplied with an attached 3-conductor mains lead. Hard

wired installation of the 5000 VA model requires removal of the attached mains

lead/strain relief assembly from the input power plate.

n Important!

The cores in the supplied 5000 VA model mains lead are colored in accordance with

the following code:

green and yellow earth

blue neutral

brown live

As the colors of the cores in the attached mains lead may not correspond to the

colored markings that identify your plug terminals, proceed as follows:

The core which is colored green and yellow must be connected to the

terminal in plug marked E or by the earth symbol

, or colored green and

yellow.

The core which is colored blue must be connected to the terminal which is

marked with the letter N or colored black.

The core which is colored brown must be connected to the terminal which

is marked with the letter L or colored red.

4.6.1 Required materials

n Input and output electrical cable

Follow the cable sizing recommendations below for a hard wired installation. Plan on

leaving at least 1.0m (3.3ft) of slack mains lead so that the UPS can be moved for

maintenance or for the addition of new loads. Output cable is needed only when any

individual load requires more than 10 Amps.
