!
ATTENTION: Disconnect and lock out power from
the drive before disassembling the drive. Failure to
disconnect power may result in death or serious injury.
Verify zero bus voltage by measuring the voltage
between the Negative Capacitor Bus and both ends of
all three bus fuses. An open fuse does not show voltage
across both ends of the fuse. Failure to measure voltage
at both ends of the fuses may result in death or serious
injury. Refer to Figure 3.5. Do not attempt to service the
drive until the bus voltage has discharged to zero volts.
Important: Before you remove connections and wires from the
drive components, mark the connections and wires to
correspond with their component connections and
terminals to prevent incorrect wiring during assembly.
1. Perform the following procedures found earlier in this chapter:
•
Opening the Drive Enclosure
•
Removing the Control Board Mounting Plate
2. Disconnect all remaining wires connecting components on the
Precharge Board Mounting Frame to any other assembly.
3. Open the Precharge Board Mounting Frame all the way to the
right.
4. Lift the frame straight up to remove it from the hinges.
Installation
Install the Precharge Board Mounting Frame in reverse order of
removal.
!
ATTENTION: Replace all guards before applying
power to the drive. Failure to replace guards may result
in death or serious injury.
