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 are facing toward the back of the
enclosure.
2. Install gaskets to the back side of the drive module. Refer to Illustration 1.6.
2a Install gasket (6) over the vent opening.
2b Align the slot gasket (7) 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 1.7.
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 N · m (170 in-lb).
6. Torque the M10 screws securing the base of the module to 19 N · m (170 in-lb).
7. Remove the DC fuses from the top of the drive module.
8. Install the upper duct assembly. Refer to Illustration 1.6.
8a Remove the paper backing from the top gasket.
8b Place the upper duct assembly on top of the drive module, making up sure the mounting holes line.
8c Secure the duct assembly to the drive module with 6 M5x12 screws. Torque to 5.1 N · m (45 in-lb).
9. Reinstall the DC fuses on top of the drive module.
10. Install the next drive module to the mounting backplate.
