Connecting the Mains Cable
Stipulated mains
cables and strain-
relief devices
The following mains cables are required to operate the power source:
Europe:
Cable cross-section 4G2.5
USA/Canada:
Cable cross-section AWG 12, extra-hard usage
Depending on the version, a strain-relief device corresponding to the cable cross-section
is fitted on the power source.
The item numbers of the different cables can be found in the Spare Parts List.
Safety
WARNING!
Danger from work that is not carried out properly.
This can result in severe personal injury and damage to property.
▶
The work described below may only be performed by trained specialist personnel.
▶
Follow national standards and guidelines.
CAUTION!
Danger from improperly prepared mains cable.
Short circuits and damage to property may result.
▶
Fit ferrules to all phase conductors and the ground conductor of the stripped mains
cable.
Connecting the
mains cable
If no mains cable is connected, a mains cable that is suitable for the connection voltage
must be fitted before commissioning.
The ground conductor should be approx. 10 - 15 mm (0.4 - 0.6 in.) longer than the phase
conductors.
A graphic representation of the mains cable connection is provided in the following sec-
tions for fitting the strain-relief device. To connect the mains cable, proceed as follows:
1
Remove the side panel of the device
2
Push in the mains cable so that the ground conductor and phase conductor can be
properly connected to the block terminal.
3
Fit a ferrule to the ground conductor and phase conductor
4
Connect the ground conductor and phase conductor to the block terminal
5
Secure the mains cable with a strain-relief device
6
Fit the side panel of the device
