You must connect the AC power cords to the external power source and to the AC power connector on each controller. After you have connected the power cords, you can turn the power on.
About this task
Consider the following power source issues:
- You should use separate power sources for each power supply.
Connecting to independent power sources maintains power redundancy.
- You can use the power cords shipped with the controller with typical outlets used in the destination country, such as wall receptacles of an uninterrupted power supply (UPS).
However, these power cords are not intended for use in most EIA-compliant cabinets.
The following illustration shows the power cords:
Warning: Risk of bodily injury. To remove all electrical current from the devices, make sure that all of the power cords are disconnected from the power source.
- Turn off the power switches in the enclosure or chassis.
- Turn off the power switches on the controllers.
- Connect the primary power cords from the cabinet to the external power sources.
- Connect the power cords to the AC power connector on each controller.
