Learn How to Connect Power Supplies to the Power Supply Network

  • The Power Supply connects to the power network through a power cord (supplied).
  • An additional fuse or circuit breaker and residual current circuit breaker on that power branch is a good choice since it will provide extra protection in addition to the unit’s internal protection.
  • A mechanical switch is also recommended within the operator‘s range and vision and possibly closer to the Power Supply.
  • Only trained personnel should open the unit’s covers and operate the breakers.
