REPLACING THE FAN MODULE
CAUTION! The rotating fan blades create a hazardous environment. Keep hands and fingers away from the fan
blades. Use only the designated pull areas to disengage the Fan Tray. Allow adequate time for fans to
spin down prior to removal.
CAUTION! Low voltage electrical shock hazard!
• Do not touch bare conductors or other potentially energized parts.
• Use appropriate safety equipment approved for use on electrical installations.
• Ensure fan module exterior of electrical connector and immediate area are clean and dry prior to
disconnection.
• Do not perform service during or while conditions of impending rain or snow are observed.
NOTE: You do not need to disconnect the power cabling from the Prism Remote Unit to replace the Fan
Module.
