Regulators electrical connection.
To reduce any trouble deriving from electromagnetic compa-
tibility, please pay attention to the following rules:
- Electrical supply wires and bus data cables must be layed
separately using a minimum distance of 2 cm.
- For cascade and zones regulators directly connected to the
electricity network, the electric wires and the bus data cables
must be layed separately.
Picture 1: minimum distance for electric insstallation
- To installl the zones managers a minimum distance of 40 cm
must be kept from other electrical appliances with electromagne-
tic emissions such as timers (relays), engines, transformers, light
regulators, microwave appliances, tv, speakers, computers, mobile
phones, etc.
Picture 2: Minimum distance from other electric appliances
- A minimum distance of 40 cm must be kept between ca-
scade regulator and zones manager. More cascade and zones
regulators connected through the bus data can be installed
one next to the other.
Bus data cable 12 V~

Recommended diametres and lenghts for the
cables.
- Screened cables are recommended for the bus data
network.
Recommended types: J-Y(St)Y 2 x 2 x 0.6
Max. lenght: 50 meters.
- e earth connection of the cable screening must be done
once only . It is not allowed to ground the same cable in
more than one point (see picture 3-4).
