5.4.4 Connection of the Loads

In order to ensure the safety of personnel during installation

work, make sure that the connections are made under the

following conditions:

♦ No mains voltage present.

♦ The loads are switched off.

♦ UPS is switched off (display completely blank).

To disconnect the PROTECT 1., carry out the following steps:

♦ Place the “maintenance switch” manual bypass on

the back of the UPS in the “bypass” position. For

this purpose, first remove the 4 screws of the

cover (no. 3, p. 26/27).

♦ Put the mains input miniature circuit breaker (no.2, p.

26/27) to the “OFF” position.

Connect the loads as follows (terminals 1.3, p. 26/27):

Connect the UPS terminals /PE = ground, N = neutral

conductor, L = phase that are marked with “OUTPUT” with the

corresponding terminals of your UPS subdistribution.

5.5 Connection of External Battery Modules

The PROTECT 1. requires the use of at least one external

battery module. Two preconfigured battery cubicle types are

available. Both versions guarantee an increase in the

attainable standby time due to their parallel connection

capability (see also chapter 2.3).
