Replacing the drive and LCL filter modules (frame R11)
Necessary equipment and tools
To replace the drive and LCL filter modules, you need:
• an installation ramp
• a set of screw drivers
• a torque wrench with an extension bar
• lifting chains
• two persons.
Safety
WARNING! Obey the instructions in chapter Safety instructions. If you
ignore them, injury or death, or damage to the equipment can occur.
• Handle the drive and LCL filter modules carefully:
• Use safety shoes with a metal toe cap to avoid foot injury.
• Lift the module only by the lifting lugs.
• Make sure that the module does not topple over when you move it on the floor:
Extend the support legs: Press each leg a little down and turn it aside. Whenever
possible secure the module also with chains.
• Do not tilt the drive module. It is heavy and its center of gravity is high. Do not
leave the module unattended on a sloping floor.
