There are three fans that are mounted in the middle of the Static Switch cabinet.

Removal

The cables from the Static Switches at the top of the cabinet needs moved out of the way in order to remove a fan.

Note: Only the Static Switch cabling that interferes with removal of the fan to be replaced needs disconnected.

  1. Perform steps in the Systems Operation, Testing and Adjusting, "Internal Component Preremoval Steps (Static Switch Cabinet)" in order to de-energize the system and gain access to internal components.
