REPLACEMENT OF EV-100 COMPONENTS
When replacing stud semiconductors such as 3REC and 4REC it is not necessary to torque these
devices to a specific value.
The use of a heat-transfer grease (such as GE Versilube G-350-M or equivalent) is recom-
mended.
When replacing module semiconductors such as 1REC, 2REC or 5REC
Remove all module connections. (As required)
Remove module by backing out the two screws at the device sides.
Clean the insulator surface with a clean rag and isopropyl alcohol.
Inspect the insulator surface for tears or cracks. If defective, replace. Wipe a light layer of
machine oil on the base and smooth the insulator into position.
NOTE: Insulator not required for 2REC and 5REC.
Coat insulator with a light coat of heat-transfer grease similar to GE-350.
Set new module on insulator and start screws back into base. Be sure to use the original
screws and washers. run screws in to base finger tight.
Check that the bottom of the module is flat against the insulator or base.
Alternately tighten the two screws by 1/4 turn until firm.
Replace all connections removed in step 1.
Capacitor
Remove nuts from capacitor connections and remove wires.
Remove hold down brackets and lift out.
Reverse procedure to replace capacitor.
22REC, 23REC and 25REC
Remove mounting screws and lift out.
NOTE: When replacing these devices, use the original hardware in the same holes, as the
inserts are used for electrical connections.
