The screen should be connected to 0 V at the mixer end only. The analogue control
cable should have a total length of less than 100 m.
When all the connections have been correctly made, tighten the locking clamps on
the two cable glands to ensure that no strain is placed on the terminals if the external
cables are tugged or stretched.
Typical example
