Take the following into account, otherwise errors
may occur:
- The length of the control cable between the control
panel and the unit connected may not exceed 50 m.
- Keep control cables away from electromagnetic fields
and interference sources such as high-voltage cables
and fluorescent light starters.
- Lay control cables out straight or roll them in a bifi-
lar coil by folding cables in half before rolling them.
As a result, the magnetic fields will cancel each other
out to an important extent.

Use Biddle control cables only. Standard modular
telephone cable is NOT suitable.
