Connect the cables as described under Control cable connection procedure (page 122)
￭ Control cable connection procedure
WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or death,
or damage to the equipment can occur.
1.
Stop the drive (if running) and do the steps in section Electrical safety
precautions (page 18) before you start the work.
2. Frames R6 to R9: Remove the cabinet fan and mounting plate above it as described in
section Connecting the power cables (page 112)
3.
Run the control cables into the drive module cubicle as described in section Grounding
the outer shields of the control cables at the cabinet entries below.
4.
Route the control cables as described in section Routing the control cables inside the
cabinet (frames R6 to R8) (page 124) or Routing the control cables inside the cabinet
(frame R9) (page 125) or Routing the control cables inside the cabinet (frames R10 and
R11) (page 126)
5.
Connect the control cables as described in sections Connecting the control unit
cables (page 126) … Wiring ground fault monitoring for IT ungrounded systems (option
+Q954) (page 132)
Grounding the outer shields of the control cables at the cabinet entry
Ground the outer shields of all control cables 360 degrees at the EMI conductive cushions
as follows (example constructions are shown below, the actual hardware may vary):
1. Loosen the tightening screws of the EMI conductive cushions and pull the cushions
apart.
2. Cut adequate holes to the rubber grommets in the entry plate and put the cables through
the grommets and the cushions.
3. Strip off the cable plastic sheath above the entry plate just enough to ensure proper
connection of the bare shield and the EMI conductive cushions.
4. Tighten the two tightening screws so that the EMI conductive cushions press tightly
round the bare shield.
