Installing the control panel and external controls
2.6.1 Special points regarding the control panel
Positioning
You may fasten the control panel either 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 30 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(Type RJ4). Standard
modular telephone cable is NOT suitable.
Multiple units operated from a single control panel
• A maximum of 8 units can be connected to a single con-
trol panel.
• Units are daisy chained using Biddle control cables and
connectors
E
and
G
.
• The total length of the control cables is not to exceed
30m(98ft). If the distance is too great, an additional con-
trol panel must be connected.
