5.4 Insulation Test
We use power supply filters in our units to meet European EMC regulations. These filters
have a discharge resistance to earth in each phase which is illustrated below. The
resistance value is 1 M

in each case. This results in an effective resistance of 333 k

for a cumulative insulation resistance measurement (L1-L2-L3 to earth).
Abb. 11: Circuit structure for mains filter
We recommend disconnecting the unit for measuring insulation resistances of a system,
as this will enable an insulation test under even this technical restriction.
5.5 Switching-on
Crushing Hazard!
During switching on the welding head can move.
Ensure that a safe distance is maintained to the welding head.
Plant set-up should only be carried out by qualified personnel and with extreme care.
Fundamental functions of the controller can be protected with a PIN, which should be
fixed by the set-up personnel.
Caution
For switching-on turn the main switch from „0“ to „1“.
Status display “01” indicates that the unit is “Ready”.
