Equipment Required:

1. Shut the PC down through Windows, and then shut off the
PC/Console circuit breaker on the breaker box. Shut off the 24VDC
circuit breaker on the breaker box.
2. Using the Phillips screwdriver, remove the 2 grounding wires from the
grounding strip on the right rear side of the rack near the electrical
panel.
3. Using the Phillips screwdriver, detach the electrical panel by loosening
the right 2 mounting screws and removing the left 2 mounting screws.
Slide the panel slightly to the left to free it.
4. Carefully turn the electrical panel around to access the rear
components, being careful not to pull any of the wires out or damage
any of the components.
5. To remove a relay, use your finger or the flat blade screwdriver to press
down the locking tab, and then slide the relay out of the DIN mount.
(Carefully move any wires out of the way if they block the selected
relay.)
6. Similarly, remove the new relay from its DIN mount by pressing down
on the locking tab and sliding the relay out. Discard the new DIN
mount as it will not be used.
7. Slide the new relay into its position and press in firmly until the locking
tab pops up into its original position. Be sure that the voltage of the
new relay matches the one being replaced.
8. Re-install the electrical panel by following steps 1–4 in reverse order.
