Figure 55 - Removal of SCR (1000…240V, 180/360A)

To Remove SCR:

• Remove shorting bar hardware

• Pry opposing heatsinks apart

•Extract SCR

To Insert New SCR:

• Apply thin film of electrical joint compound to

surfaces of SCR

• Install SCR so that it is seated in locating pin of

heatsink (note orientation of SCR).

• Pry heatsinks to close gap, ensuring that SCR is

seated properly in both its locating pins.

• Rotate SCR so that all leads have same direction.
