Spare Parts and Replacement Procedures 8 - 13
2. Remove the three nuts that secure the shield to the side of
the rectifier frame, and remove shield.
3. The following components should be exposed: T3, L1, L2,
K1, K2, K3, and T2.
Transformer (T3)
1. Remove the quick-disconnect connectors from T3.
2. On left side of rectifier frame, loosen the bottom two
mounting nuts of T3, then remove the top two nuts.
3. While supporting the weight of T3, slide it up and out.
K1 Contactor
Relay
1. If you are moving K1 out of the way as part of the process
of getting to L1, then it is only necessary to carefully (the
terminal tabs are fragile) remove the terminal screws and
wires (with terminals) from the top of K1. The bottom
leads of K1 can remain attached. Skip to Step 3.
2. If you are removing K1 in order to replace it, then perform
Step 1 and then remove the bottom leads from K1 by
removing their screws. Observe the same caution as in
Step 1.
3. Remove the bottom two nuts and loosen the top nut in
order to remove K1.
K2 or K3 Relay
(Contactors)
Relay K3 is found in 480 VAC input rectifiers only.
1. Remove quick-disconnect connectors from relay.
2. To remove the relay, remove the top nut and loosen the
bottom nut.
AC Inductors (L1
or L2)
The L1 inductor is located behind T3, and the L2 inductor is
located behind K1 and K2.
1. The transformer (T3) must be moved in order to access L1
or L2, but it is not necessary to remove all of the T3 leads.
Remove the top four (non-yellow) quick-disconnect
connector leads from T3 (the remaining leads to T3 are
long enough to allow T3 to rest on the floor of the
