Machine is designed to withstand 3 x 440 V voltage continuously (see technical data). See to
it that voltage is kept within admissible limits especially when mains supply is taken e.g. from
combustion engine generator.
If the mains has undervoltage (under approx. 300 V) or overvoltage (over approx. 480 V)
machine control stops to operate automatically.
