Safety

WARNING

DISCHARGE TIME

The frequency converter contains DC-link capacitors, which
can remain charged even when the unit is o. High voltage
can be present even when the warning indicator lights are
o. Failure to wait 20 minutes after power has been
removed before performing service or repair work, could
result in death or serious injury.

•

Stop the motor.

•

Disconnect the AC mains, permanent magnet type
motors, and remote DC-link supplies, including
battery back-ups, UPS, and DC-link connections to
other frequency converters.

•

Wait 20 minutes for the capacitors to discharge fully,
before performing any service or repair work.

•

Measure the voltage level to verify full discharge.

Mounting the Drive Modules

1. Install the mounting backplate to the cabinet rails, making sure that the pem studs/nuts face the back of the enclosure.

2. Install both exhaust vent gaskets (3) to the back side of the drive module. Refer to Illustration 1.5.

3. Align the slot gasket (2) with the lower mounting holes in the drive module and install the gasket onto the drive module.
See Illustration 1.6.

4. Assemble the 2 base mounting plates by attaching the gasket (4) onto the base mounting plate (5). Refer to
Illustration 1.6.

5. Insert an M10 screw through the base mounting plate/gasket assembly and loosely fasten into the mounting backplate.
Perform this step again for the other base mounting plate/gasket assembly. Make sure that the screws are secure since
the base of the drive module rests on these screws.

6. Slightly lean the top of the drive module forward and set the cutouts in the base of the module onto the lower 2 M10
screws in the mounting backplate.

7. Slowly push the top of the drive module back against the mounting backplate until the top 2 holes on the module line
up with the 2 mounting holes in the mounting backplate. Secure the top of the drive module using 2 M10 screws (4) and
torque to 19 N · m (170 in-lb). See Illustration 1.5.

8. Torque the M10 screws securing the base of the module to 19 N · m (170 in-lb).

9. Install the top plate assembly. Refer to Illustration 1.10.

9a Place the gasket (8) over the grill opening on the top of the unit.

9b Place the top plate (2) over the gasket. Secure it with the 11 M5x12 screws included in the kit.

Torque to 5.1 N · m (45 in-lb).

10. Install the next drive module to the mounting backplate.
