Connecting the mains cable
General A strain-relief device for the following cable cross-sections is fitted to the power source:
*) Canada/US cable type: extra-hard usage
Strain-relief devices for other cable cross-sections must be designed accordingly.
Stipulated mains
cables and strain-
relief devices
*) Canada/US cable type: extra-hard usage
The item numbers of the different cables can be found in the spare parts list towards the
end of the document.

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 PE conductor should be approx. 10 - 15 mm (0.4 - 0.6 in.) longer than the phase con-
ductors.
An illustration of the mains cable connection can be found in the following sections: "Fitting
the strain-relief device" or "Fitting the strain-relief device for Canada / US". To connect the
mains cable, proceed as follows:
Remove the side panel from the device
Push the mains cable in far enough to make it possible to connect the PE conductor
and the phase conductors to the block terminal properly.
Fit ferrules to the PE conductor and phase conductors
Connect the PE conductor and phase conductors to the block terminal
Use the strain-relief device to secure the mains cable
Fir the side panel of the device

CAUTION! If no ferrules are used, there is a risk of injury and damage from short
circuits between the phase conductors or between the phase conductors and the
PE conductor. Fit ferrules to all phase conductors and the PE conductor of the
stripped mains cable.
