2. Snap the old board up off the four plastic standoffs and remove.
3. Orient the new board with the stab-on connectors 06 and 16 at the top
(DC boards) or stab-on connectors 81, 82 and 83 in the lower left (AC

4. Reconnect the leads.
!
ATTENTION: Disconnect and lock out power from the system
before disassembling the bridge. 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 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.
