Installation and User Manual

2.8Connecting the Input and Output Power Cables to the Input/Output Box

WARNING This type of connection must be carried out by qualified electrical personnel.

Before carrying out any connections, check that battery circuit breaker 14 is OFF and that the upstream protection devices (Normal and Bypass AC

sources) are open (OFF).

EX 5/7/11 RT UPS always comes from factory with Normal and Bypass AC inputs already connected together, using a shunt.

Knockout die stamp circles (on terminal block cover) have two sizes that fit either plastic or metal coupling. Plastic coupling is for flexible cordage

and metal coupling is for solid wires. Knock out appropriate circle for your application.

2.Remove bottom cover plate as shown.

3.Typical plastic strain relief installation:

a)Secure strain relief body onto the knockout plate.

b)Strip the jacket back to expose the three wires. Strip the insulation of each wire back 1/2”. Insert the ferrules as shown to each wire.

CAUTION: Always connect the earth ground wire first.

c)Slide the cordage into the strain relief and secure the wires into the terminal blocks using the guide printed on bottom of I/O box.

d)Secure the cordage retainer nut.

4.Typical 90° metal conduit installation.

a)Secure strain relief body to knockout plate as shown.

b)Insert three wires through flexible conduit and bend 90°.

c)Strip the insulation back 1/2” to expose solid wire and secure three wires into the terminal block using guide printed on bottom of I/O box.

CAUTION: Always connect the earth ground wire first.

d)Install strain relief cover using two screws.
