Voltage reducing device

Only machine variants with the (VRD/SVRD/AUS/RU) code are equipped with a voltage reduction device
(VRD). The VRD is used for increased safety, especially in hazardous environments such as shipbuilding,
pipe construction or mining.
A VRD is mandatory in some countries and required by many on-site safety instructions for power
sources.
The VRD > see 4 chapter signal light is illuminated when the voltage reduction device is operating without
fault and the output voltage is reduced to a value specified in the relevant standard (see technical data).
