7 Start-Up
The start-up procedure is the same for the various UPS versions from
10 kVA to 80 kVA. Prior to start-up, ensure that the preset unit
specifications match the battery specifications.
For parallel systems, see description of "Parallel Operation"!
i
NOTE:
The start-up instructions of the battery manufacturer must be
complied with. Any necessary parameter modifications must be
made by our service personnel or via the DOU.
A phase-rotation indicator and a voltmeter are required for the work
that follows.
CAUTION:
When the mains is connected, potentially fatal voltages are
applied to the terminals.
Always observe the safety regulations!
Starting the UPS (see also Figure 3)

Preparing Start-up of the UPS (Individual Unit)
Step Action
1
Q1 and battery isolator (external) to the "OFF" position.
2*
Q29 internal option set to position "2" manual bypass.
3 Remove
connection
cover.
4
Connect the mains voltage for the rectifier circuit and SBS circuit.
5
Measure the mains voltage at terminal X1 (outer conductor/outer
conductor). The voltage should be 400 V.
Measure the mains voltage at terminal X4 (outer
conductor/neutral conductor). The voltage should be 230 V.
6
Check the rotating field on terminal X1. L1, L2 and L3 clockwise
rotation.
7
Switch off the mains voltage for the rectifier circuit and
SBS circuit.
8
Eliminate any errors if necessary and repeat the steps.
9
Replace the connection cover.
* Step only required when Q29 is installed
