10.1 Rectifiers
The fan on the individual rectifiers is designed for very high reliability and long life. During year six of the life of the
product the manufacturer recommends replacement of the fan assembly.
10.1.1 Fan replacement
1. Lift the locking handle and slide the module 10 cm (4 in.) out of the shelf. Wait ten minutes for the module
capacitors to discharge and then slide the rectifier out of the shelf.
2. Remove the two bottom screws that secure the front panel to the module chassis.
3. Push in the two plastic protrusions on top of the rectifier and disengage the front panel and attached fan from
the rectifier.
4. Disconnect the fan cables from the module by pulling out the fan cable connector.
ATTENTION
Circuit cards, including semiconductor devices, can be damaged by static electricity. Always
wear a grounded wrist strap when handling or installing circuit cards.
WARNING
Use extreme care when working inside the unit while the system is energized. Do not make
contact with live components or parts.
ATTENTION
Ensure redundant modules or batteries are used to eliminate the threat of service interruptions
while performing maintenance on the system’s alarms and control settings.
