Replacing a frame D7T supply module
WARNING!
Only qualified electricians are allowed to do 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!
Use extreme caution when maneuvering the supply module. It is heavy and has
a high center of gravity. Ignoring the following instructions can cause physical
injury, or damage to the equipment.
• Use the required personal protective equipment: safety shoes with metal
toe cap, protective gloves, etc.
• When working above the module, be careful not to drop anything into the
module.
• Use a lifting device:
• Attach the lifting device securely to the module lifting eyes before
removing the module fastening bolts. Keep the lifting device attached
to the module until you have lifted the module onto a pallet and made
sure that the module is supported and cannot fall over.
• Lift a replacement module only with a lifting device. Keep the lifting
device attached to the module during the work until you tighten the
module fastening bolts.
• A lifting device is available from ABB. See Converter module lifting
device for drive cabinets hardware manual (3AXD50000210268
[English]).
• Do not tilt the module. Do not leave an unsupported module unattended
especially on a sloping
floor.
• When you push the replacement module into the cabinet, keep your fingers
away from the module edges to avoid pinching them between the module
and the cabinet.
Note: Before you start replacing the supply module, make sure that the connector at
the end of the auxiliary power supply cable in the cabinet is compatible with the
counterpart in the module. Black connector is compatible only with the black
counterpart, and gray connector only with the gray counterpart. If the connectors are
not compatible, replace the connector in the new module. Use the connector in the
old module, or order suitable connector from ABB. Refer to +V112 connector
replacement guide for ACS880-x04 R8i/D8T/D7T module change (3AXD50001060015
[English]).
Obey these instructions for replacing the module. Refer to the drawings below.
1. Stop the drive and do the steps in section Electrical safety precautions (page 21)
before you start the work.
2. Open the cubicle door.
