condition. As a result of this fault, the active converter is also turned off, but
this is done via software operation. The firing of IGBTs in the active
converter can be disabled independently of any software control by opening
the connection between terminals 13 and 14 on the active converter control
assembly terminal block A12-P1. This action also genrates a fault in the
inverter to enunciate this condition. Wiring diagrams are shown in
Figure 1.5 and on page C-3 .

Mounting the Drive,
Determining Wire Routing,
and Grounding This section shows how to mount the drive and properly ground it. Also
described is the wiring to be routed in and out of the drive.
Lifting and Mounting the Power Module
Use the following procedure to lift the LPM20 power module and mount it
in the required enclosure:
1. Install two s-hooks into the power module to serve as lifting points. Two
1-inch through holes are provided in the sheet metal chassis.
2. Connect 18 inches (nominal) of chain between the s-hooks and secure
them with a clevis clamp.
3. Using an overhead or portable hoist (minimum 1/2-ton rated capacity),
attach a free-fall chain to the chain secured to the drive. Take up any
vertical slack in the chain.
4. Using the hoist, lift the power module from the horizontal shipping pallet.
5. Position the power module in the enclosure.
6. In order to maintain a flat mounting surface and to ensure that bolt tightness
is maintained, use flat washers and split-ring lock washers under the bolt
heads. Refer to
Figure 1.5 for power module mounting dimensions.
7. Remove the s-hooks and chain.

ATTENTION: Most codes require that upstream branch
circuit protection be provided to protect input power wiring.
