rectifier). Remove T3 from the frame of the rectifier per
Steps 2 and 3 of Procedure D in this part.
2. For L2 removal, it is necessary to remove all three relays;
K1, K2, and K3 (for 480 VAC input units only). Perform
procedures described above in “K1 Contactor Relay” on
the previous page and “K2 or K3 Relay (Contactors)” on
this page to remove the relays.
3. For either L1 or L2 removal, cut the cable ties from the
inductor leads. Then, disconnect the quick-disconnect
connector leads (coming from L1 or L2) from the
corresponding capacitor and thyristor (C7 and Q2 for L2,
or C5 and Q1 for L1).
4. To remove inductor L1 or L2, remove all four of the nuts
that mount it to the rear wall (make sure the weight is
supported adequately).
CA1 Board
(Snubber
Network)
1. Remove quick-disconnect connectors from CA1.
2. Remove the board from each of the six spring-tab support
standoffs (one at a time) by depressing the spring tab with
a screwdriver blade while pulling out on that portion of the
board.
3. During reassembly, the CA1 board can be replaced by
pushing all six of the holes down over the support
standoffs simultaneously. Verify that all of the tabs lock in
place.
Thyristors (Q1 or
Q2)
1. Remove quick-disconnect connectors from the thyristor to
be removed.
2. Remove the nut that holds the thyristor to the bracket.
Retain the thermal pad for reinstallation.
AC Capacitors
(C5 or C7)
1. Remove quick-disconnect connectors from the capacitor.
2. Remove the three nuts that hold the capacitor and the
capacitor clamp to the rectifier frame.
3. Remove the clamp from the capacitor.
