5.1.9.2 Adjusting the power source to the mains voltage
The mains voltage is adapted by replugging the operating voltage plug on the printed circuit board VB xx0
into the power source.
The machine can be reconnected between three possible voltage ranges:
1.
380 V to 400 V (ex works)
2.
440 V to 460 V
3.
480 V to 500 V
Figure 5-8
• Switch off machine at the main switch.
• Disconnect mains plug.
• Loosen the fastening screws from the housing cover. Open the housing cover at the side and lift it up.
• Reconnect operating voltage plug (printed circuit board VB xx0) to the corresponding voltage range of
the supply voltage (380V/400V ex works).
• Hook housing cover from above into the aluminium continuous casting profile flexFit and secure with
fastening screws.
• Install a mains plug which is permissible for the selected mains voltage to the mains cable. Identify the
selected mains voltage on the rating plate and on the adhesive label of mains connection cable.
5.1.9.3 Re-commissioning
WARNING
Dangers resulting from failure to perform test after conversion!
Before reconnection, “Inspection and Testing during Operation” according to
IEC/BS EN 60974-4 “Arc welding systems – Inspection and Testing during Operation”
has to be performed!
• Perform test to IEC / DIN EN 60974-4!
