Replacing the standard drive module
WARNING! Obey the safety instructions in chapter Safety instructions. If
you ignore them, injury or death, or damage to the equipment can occur.
• Handle the drive module carefully:
• Use safety shoes with a metal toe cap to prevent foot injury.
• Lift the drive module only by the lifting lugs.
• Make sure that the module does not topple over when you move it on the floor:
Open the support legs by pressing each leg a little down (1, 2) and turning it aside.
Whenever possible secure the module also with chains.
• Do not tilt the drive module (A). It is heavy and its center of gravity is high. The
module overturns from a sideways tilt of 5 degrees. Do not leave the module
unattended on a sloping floor.
1. Stop the drive and do the steps in section Precautions before electrical work on page
18 before you start the work.
2. Remove the clear plastic shrouds on the power cables and parts in front of the drive
module (if present).
3. Disconnect the power cables.
4. Drives with external control unit:
Disconnect the cables between the drive module and
the control unit. See section Connecting the external control unit to the drive module
on 103.
5. Drives with internal control unit (option +P905):
Disconnect the external control cables
connected to the control unit. See section Internal control unit (option +P905) on page
119.
