WARNING!
Only qualified electricians are allowed to this work. Read the complete safety
instructions of the drive. Ignoring the instructions can cause physical injury or
death, or damage to the equipment.
WARNING!
Ignoring the following instructions can cause physical injury, or damage to the
equipment:
• Use extreme caution when maneuvering a supply module that runs on wheels.
The modules are heavy and have a high center of gravity. They topple over
easily if handled carelessly.
• When removing a module which is equipped with wheels, pull the module
carefully out of the cubicle along the ramp. While pulling on the handle, keep
a constant pressure with one foot on the base of the module to prevent the
module from falling on its back.
• When replacing a module which is equipped with wheels, push the module up
the ramp and back into the cubicle. Keep your fingers away from the edge of
the module front plate to avoid pinching them between the module and the
cubicle. Also, keep a constant pressure with one foot on the base of the module
to prevent the module from falling on its back.
• Do not tilt the module. Do not leave the module unattended on a sloping floor.
• Do not use the ramp with plinth heights of over 50 mm.The ramp supplied with
the drive system is designed for a plinth height of 50 mm (the standard plinth
height of ABB cabinets).
Note: As an alternative to using the extraction/installation ramp, a lifter is available from
ABB Service. For more information, contact ABB Service, or see Lifter for air-cooled drive
modules user's guide (3AXD50000332588 [English]).
1. Disconnect the drive from the AC power line and make sure it is safe to start the work.
See section Electrical safety precautions (page 46).
2. Open the cubicle door.
3. Undo the four screws of the shroud in the upper part of the cubicle. Remove the shroud.
4. Unplug the signal connector cable on top of the module.
5. Remove the screws in the busbars on top of the LCL filter module. Be careful not to drop
the screws inside the module!
6. Remove the two screws that fasten the bottom of the module to the base of the cabinet.
7. Install the module pull-put ramp: lift the module pull-out ramp against the cabinet base
so that the hooks of the base go into the ramp's holes.
8. Remove the two fastening screws that fasten the top of the module to the cabinet frame.
9. Pull the module carefully out of the cabinet along the ramp. While pulling on the handle,
keep a constant pressure with one foot on the base of the module to prevent the module
from falling on its back.
