Voltage reducing device
The machine can be equipped with a VRD(Voltage-reducing device) to increase safety, particularly in
hazardous environments such as those in shipbuilding, pipe construction or mining (identified with name
prefix "VRD").
The VRD signal light comes on when the voltage reduction device is operating perfectly and the output
voltage is reduced to the value specified in the relevant technical standard..
