Additional cabling and EMC instructions
Follow these instructions for trouble free operation and to ensure compatibility with the European EMC directive.
Motor cable
The motor cable must be a symmetrical three conductor cable with a concentric PE conductor or a four conductor cable with a
concentric shield. Braided metallic screen is recommended, e.g. type MCCMK (NK Cables).
- Twist the cable screen wires together into a bundle, and connect to the earthing terminal
. Keep the bundle as short as possible.
- Clamp the cable screen as shown in the figure when internal or external EMC filter is used.
- At the motor end the motor cable screens must be earthed 360 degrees with an EMC cable gland or the screen wires must be twisted
together into a bundle not longer than 5 times its width and connected to the PE terminal of the motor.
Control cables
Control cables must be multi-core cables with a braided copper wire screen.
A double shielded twisted pair cable is recommended for the analogue
signals.
- Twist the screen together into a bundle and connect to terminal SCR. Keep
the bundle as short as possible.
- Clamp the control cable as shown in the figure (EMC units only).
- Route the motor cable away from the control wires and the power supply
cable to avoid electromagnetic interference (distance > 20 cm).
Note:
Never mix 24 VDC and 115/230 VAC signals in the same cable.
