2.6.1 Special points regarding the control panel
Positioning
•
You can attach the control panel to the electronics mod-
ule, to the wall or to a standard junction box.
Cabling
Note:
n
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.
Note:
n
Use Biddle control cables only. Standard modular
telephone cable is NOT suitable.
2.6.2 Mounting and connecting the control panel
1. Lay the control cable.
2. Slide the control panel out of the wall holder.
