Before you remove the DC precharge module, all applicable safety guards, anchor bolts, and wire harnesses are disconnected or removed, and the
service cart is anchored to the control cabinet with a power module loaded and secured. The DCPC module lift is installed on the power module.
Follow these steps to remove the DC precharge module.
1. Pull the DC precharge module a maximum of 2 inches
(50 mm) out of the cabinet. Do not exceed 2 inches (50
mm).
This position allows the DC precharge module to mate
with the carriage.
2. Remove the locking bar.
3. Secure the DC precharge module to the DCPC module
lift.
a. Remove the locking pin from the DCPC module lift.
b. Release the carriage auto-lock.
Pull back on the carriage handle and lift the auto-lock
lever.
c. Slide the carriage to connect with the DC precharge
module.
Use the jackscrew on the service cart to adjust the height
of the power module when removing the DC precharge
module. See

4. Connect the DCPC module lift to the DC precharge module.
a. Insert the locking bar through DCPC module
lift and the DC precharge handle.
b. Turn the locking bar counterclockwise to engage
the lock into the channel.
5. Tighten the leveling knobs until they contact the
DC precharge module.
The leveling knobs are used to adjust the pitch of the
DC precharge module during removal. Use the
leveling knobs and the jackscrew on the service cart
to adjust the alignment between the cabinet and the
DC precharge module as the DC precharge module
is removed.
