5.3.2Connection of the one phase mains connector

To protect the personnel during installation, ensure that the connection takes place und the following precautions:

No mains power present.

Loads are switched of.

The PROTECT C. is switched of (display completely off).

To activate the PROTECT C. execute the following steps:

Set Manual bypass „Maintenance Switch“ to “Bypass” on the rear of the UPS. Remove the four screws of the cover (Pos. 2, page 26).

Set the mains input circuit breaker (Pos. 3, page 26) to position “OFF”.

Connect the UPS terminal „ / PE “ (Ground) with the associated ground terminal in the distribution cabinet.

Connect the mains supply cable with the NS distributor to the „INPUT“ terminal in the UPS:

/ PE = Ground

N= Neutral line

L = Phase

Check the bridge between „JP1“ and „JP2“ (Terminal label „JUMPER“).

Only remove the cable, when using the PROTECT C. in parallel operation with appliances of the same type (see chapter 9).

5.3.3Preparation for the load connection

Before connecting the loads to the UPS, it is necessary to ensure that the rated power of the label of the UPS is higher or equal to the sum of the power consumption of the loads.

The output of the PROTECT C. should supply the sub distribution in separate power circuits. Check for a selective protection of the circuits.

For the connection between PROTECT C. and the sub distribution cable diameters according to table 1 on page 30
