4 Assembly
4.1 Mounting electrical connection 1
1. Align the plug 1 to match the socket.
2. Insert the plug 1 into the socket.
3. Tighten the screw-type lock of the plug 1. Tightening torque: 0.4 Nm ± 50%
4.2 Mounting electrical connection 2
1. Align the plug 2 to match the socket.
2. Insert the plug 2 into the socket.
3. Tighten the screw-type lock of the plug 2. Tightening torque: 0.4 Nm ± 50%

Tab. 2: Wiring
4.4 Strain relief
Strain relief for movable wiring
• Install the strain relief and mountings over a wide area to prevent damage to
the interior structure and the exterior shell.
4.5 Mounting in energy chain
1. Lay the chain out lengthwise.
2. Place the cables on the chain, making sure they are not twisted.
3. Separate cables from each other using separators/drilled holes.
4. Do not connect cables together.
5. Maintain space X. X > 10% of the cable diameter D.
If the chain is suspended vertically: increase space X.
Align chain in the operating position:
–Make sure that the radius is greater than the bending radius R of the
cables.
–Cables can move freely in the bending radius KR of the energy chain.
ÄCables are not forced through the chain.
7. Mount the energy chain è corresponding instructions.
Fasten cables:
–with short energy chains (length < 1 m) at both ends of the chain
–with long sliding energy chains (length > 1 m) only at the driver end
9. Do not move cables all the way to the fastening point.
ÄMounting space A between the fastening point and bending movement
is maintained.
NOTICE
Damage to cables if the chain breaks.
• Replace cables after a chain break.
NOTICE
Malfunction and material damage due to vertically suspended cables.
The cables stretch.
• Regularly check the length of the cables.
•Readjust the cables if required.
