Important: Make sure that the arrows on the fan are pointing towards
the top of the cabinet.
5. Start the screws and lockwashers in the four corners.

!
ATTENTION: Disconnect and lock out power from the system
before disassembling the drive. Failure to disconnect power may
result in death or serious injury. Verify bus voltage by measuring
the voltage between +DC and –DC on terminal block TB1 which
is located at the bottom of the 1336 Drive in the Inverter Bay. Do
not attempt to service the drive until the bus voltage has
discharged to zero volts.
