7.4 Power Circuit and Cable Requirements
A power circuit (See table below) must be provided for connection of the unit. This circuit must be protected
with the required safety devices, i.e. a main switch, a slow blow fuse on each phase and an earth leak
detector.
When using residual current operated circuit breakers, be sure to use a high-speed type 200mA rated
residual operating current.
Note: Select the power supply cable in accordance with relevant local and national regulations.
