the motor operation
• See Figure 3-51 for through-panel mounting cut-out details.
• Pass the cables through the hole in the panel and install the
through-panel grommet.
• Install the through-panel mounting bracket.
• Install the DC terminal cover grommets supplied in the accessory
box with the drive, to the cables. To ensure a good seal, the
grommets are a tight fit. Lubrication may be required to help install
the grommets to the cables.
• Terminate the cables with suitable crimps and connect to the BR
and +DC terminals. Tighten the screw terminals to a maximum
torque of 1.5 Nm (1.1 lb ft).
• Replace both terminal covers.
• Remove the DC cover as detailed in section 3.3.1 Removing the
terminal covers on page 29.
• Remove the two break-outs that line-up with the BR and +DC
terminal connections as detailed in section 3.3.2 Removing the
finger-guard and DC terminal cover break-outs on page 32.
• Lift the hinged fan baffle by pushing plastic tabs in the direction
shown (1). Push tab in the direction shown (2), and lift the baffle as
shown (3).
• Remove the metal heatsink baffle plate by removing the two
screws. These two screws are no longer required.
• Remove 5mm (0.197in) from the length of the clip on the plastic
fan baffle.
• Install clip to heatsink in the position shown in diagram opposite.
Route the long cables of the resistor assembly between the fins of
the heatsink as shown in Figure 3-58.
• Install the heatsink baffle plate in place with the cables routed
underneath. Ensure the cables are not trapped between a
heatsink fin and the baffle plate.
• Install the braking resistors to the heatsink. The resistors are
installed with captive screws.
• The screws should be tightened to a maximum torque of 2.0 N m
(1.5 lb ft).
• Close the hinged fan baffle.
• Install cables to heatsink clip.
