Assembling
Installing the left and right covers and rails
1. Position the left cover (Pos. 1) from the inside onto the threaded bolts and fasten it using
M5 locking nuts (Pos. 197).
2. Insert the straight rail (Pos. 7) and slanted rail (Pos. 8, only for frame size D) by pushing
them between the connected cables and use one M4×12 combination screw for each (Pos.
109) at Pos. 1 to hold them.
3. Position the right cover (Pos. 2) onto the threaded bolts and fasten it using M5 locking nuts
(Pos. 197).
4. Attach the rails ((Pos. 7 and Pos. 8) with a further M4×12 combination screw (Pos. 109).
Make sure that all screws and nuts are tightened to the specified torque.
Installing the cover with cable rests and shield clamps
1. Insert the front cover (Pos. 6) into the cover with cable rests (Pos. 3) and use expanding
rivets (Pos. 174) to fasten it from outside to inside (pre-assembly).
2. Attach the pre-assembled cover with cable rests (Pos. 3 + Pos. 6 + Pos. 174) to the side
covers (Pos. 1 and Pos. 2) using M4×12 combination screws (Pos. 109). Apply the correct
tightening torque.
3. Snap shield clamps (Pos. 160) over the cables into the cover (Pos. 3) as required.
4. Use cable ties to fasten the cables to the cover (Pos. 3).
Attaching the bottom cover (cables in front, center and rear)
1. Attach the cable at the front (Pos. 9 or Pos. 12), for frame size D cover with cable at the
center (Pos. 10 or Pos. 13) and cover with cable at the rear (Pos. 11 or Pos. 14) to the side
covers (Pos. 1 and Pos. 2) using 4 M4×12 combination screws (Pos. 109) each. Apply the
correct tightening torque.
Note
• Pos. 9 and Pos. 11 apply unaltered for frame size A (see schematic on page 2)
• For frame size B, use either Pos. 9 and Pos. 11 for small cable diameters or Pos. 12 and
Pos. 14 for large cable diameters. If necessary, remove the break-out pieces in the cable
openings to match the cable outlets to the actual cable diameters (see graphic diagram on
Page 5).
• For frame size C, use either Pos. 9 and Pos. 11 for small cable diameters or Pos. 12 and
Pos. 14 for large cable diameters. If necessary, remove the break-out pieces to access the
cable openings for the protective ground cable. (see the diagram on Page 8).
• For frame size D, use either Pos. 9, Pos. 10 and Pos. 11 for small cable diameters or Pos.
12, Pos. 13 and Pos. 14 for large cable diameters. Use all covers as supplied without
making any changes. (see the diagram on Page 12).
Installing the side covers
1. For frame sizes C and D, use 6 expanding rivets each (Pos. 174) to fasten the side covers
(Pos. 5) to unit side walls on both sides, working from the outside to the inside.
