7.10 Installing the Control Cables
7.10.1 Requirements for the Control Cables
Requirements for the control cables:
l Wire size: 0.25–4 mm
2
(22–12 AWG)
l Wire size with end ferrule: 0.25–2.5 mm
2
(22–14 AWG)
l Wire stripping length: 10–12 mm (0.4–0.5 in)
Make sure that the control cables are long enough to prevent tight bends in the cables between the control compartment and the frame
of the drive. Use a flexible cable with fine-stranded wires meant for mobile installation.
