Removing and Installing a Power Supply
The FS7500 controller supports the 502 W Energy Smart power supply modules.
Note: The recommended installation for the FS7500 includes two power supplies. The second
power supply ensures continued operation and high availability in the event of a power or power
supply failure.
Note: Replace the power supply that has the flashing indicator with a power supply that matches
the capacity of the other installed power supply. Swapping the other power supply to
create a matched pair can result in an error condition and unexpected controller shutdown.
Removing a Power Supply
1. Disconnect the power cord from the power source and the power supply that you intend to
remove. Remove the cords from the strain relief straps.
2. Press the release latch and slide the power supply out of the controller chassis.
