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.

Installation

NOTICE

If both a bus bar kit and a back-channel cooling kit are
being installed in the cabinet, install the back-channel
cooling kit rst.

NOTICE

APPROVALS AND CERTIFICATIONS

This VLT® Parallel Drive Modules back-channel cooling kit is
UL 508C compliant. These installation instructions describe
how to install the back-channel cooling kit which, if

openings.

2. Drill the 12 screw holes around the exhaust (top) vent openings and insert the 12 M5 X 12 pem studs.

3. Drill the 12 screw holes around the intake (bottom) vent openings and insert the 12 M5 X 12 pem studs.

Assembling the Lower Duct Enclosure

The front cover gasket (10) and front cover plate (9) are not installed during the lower duct assembly. They are installed once the
duct is attached to the mounting backplate.

1. Install the left and right side gaskets (6) against the back side of the duct enclosure (11).

2. Place the grill (7) on top of the gaskets. Secure the grill to the enclosure using 4 M5 nuts. Torque to 5.1 Nm (45 in-lb).

3. Install the gasket (8) on top of the grill.

4. On the base of the enclosure, install the gasket (12) and then the base cover plate (13) on the enclosure. Secure with 10
M5 nuts and torque to 5.1 Nm (45 in-lb).

5. On the top of the enclosure, install the gasket (3) and then the top plate (13) on the enclosure. Secure the top plate to
the enclosure with 4 M5 nuts. Torque to 5.1 Nm (45 in-lb).

6. Install the gasket (1) on the top plate. Leave the paper backing on the adhesive until ready to install on the drive module.

7. Turn the duct enclosure over so the base of the enclosure is facing up. Install the top side gaskets (4) on the sides of the
top plate (2).

8. Place a top side cover (5) on each gasket (4). Secure each cover with 5 M5 nuts and torque to 5.1 Nm (45 in-lb).

Mounting the Drive Modules

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

2. Install gaskets to the back side of the drive module. Refer to Illustration 1.5.

2a Install gasket (3) over the exhaust vent opening.

2b Align the slot gasket (5) with the lower mounting holes in the drive module and install the gasket onto the

drive module.

3. Install the base mounting plates. Refer to Illustration 1.6.

3a Assemble the 2 base mounting plates by attaching the gasket (4) onto the base mounting plate (5).

3b Insert an M10 screw (6) through the mounting plate/gasket assembly and loosely fasten into the mounting

backplate. Perform this step again for the other mounting plate/gasket assembly. Make sure that the screws are
secure since the base of the drive module rests on these screws.

4. 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.

5. 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 and
torque to 19 Nm (170 in-lb).

6. Torque the M10 screws securing the base of the module to 19 Nm (170 in-lb).

7. Install the top plate assembly. Refer to Illustration 1.5.

7a Place the gasket (3) over the grill opening on the top of the unit.

7b Place the top cover (1) over the gasket. Secure it with the 11 screws included in the kit.

Torque to 5.1 Nm (45 in-lb).

Installing the Lower Duct Assembly to the Mounting Backplate

Refer to Illustration 1.6 for the following steps.

1. Remove the paper backing from the top plate gasket.

2. Place the lower duct assembly up against the drive module base, making sure the mounting holes line up.

3. Secure the lower duct assembly to the base of the drive module using 7 M5x16 screws. Torque to 5.1 Nm (45 in-lb).

4. Secure the grill on the lower duct assembly to the mounting backplate using 4 M5x12 screws. Torque to 5.1 Nm
(45 in-lb).

5. On the front side of the lower duct, install the front cover gasket (10) and then the front cover plate (9). Refer to
Illustration 1.4. Secure with 8 M5 nuts and torque to 5.1 Nm (45 in-lb).

6. Install the lower duct assembly for the next drive module.
