Make sure that the power supply voltage is the same indicated on the instrument.

Switch on the power supply only after that all the electrical connections have been completed. Supply voltage range must be determined in order. While installing the unit, supply voltage range must be controlled and appropriate supply voltage must be applied to the unit.

There is no power supply switch on the device. So a power supply switch must be added to the supply voltage input.

Power switch must be two poled for seperating phase and neutral, On/Off condition of power supply switch is very important in electrical connection. External fuse that on Vpower supply inputs must be on phase connection. External fuse that on Zpower supply inputs must be on (+) connection.
