5.1Safety of Personnel

Note the following points when setting up the UPS system and its external battery units (special accessories):

♦Disconnect the unit from the power supply

♦Secure the unit against being switched back on

♦Verify that the unit is disconnected from the power supply

♦Earth and short-circuit the unit

♦Provide protection by covers or barriers for any neighbouring live parts

5.2Mains Connection (General)

In order to ensure the correct functioning of the UPS and its additional equipment, it is necessary to equip the mains cable with the corresponding fuses.

5.2.1Checklist for Cable Connections

The connection and earthing terminals of all PROTECT 1. units are structured in a similar way. The cables are connected as follows:

♦Remove terminal cover (retain the four screws).

♦Insert the cables to be connected into the terminal space of the PROTECT 1. from the rear.

♦Connect the wires of the supply lines to the corresponding terminal block. Connect the PE to the terminal block of the PROTECT 1.100 or to the strain relief unit of the PROTECT 1.150 or 1.200.

♦Fasten the supplied cable clamping unit (no. 9, p. 27/28) with the previously removed screws.

In the case of the PROTECT 1.150 and 1.200, also remove the lateral earthing bolts beforehand and use them to fasten the cable clamping unit as well.

♦Check to ensure that the cables are secured correctly and tighten the fixing bolts if necessary.

♦Remove any cable debris, tools, bolts, etc. from the connection panel.

♦Mechanically secure the cables with the strain relief clamps of the cable clamping unit.
