Energy management

Maximum number of devices,

maximum distances and absorptions

A system can manage up to 99 zone

addresses. Up to nine addresses

dedicated to the actuators can

be managed for each zone. The

maximum number of devices which

can be connected to the BUS also

depends on their total absorption

and the distance between the

connection point and the power

supply. The power supply can

supply up to 1200 mA (E46ADCN)

or 600 mA (E49) and the maximum

number of devices which can be

connected to the BUS is determined

by summing the absorption of all

the items and making sure that the

total does not exceed the capacity

of the power supply. For the

calculations mentioned above, refer

to the TECHNICAL DATA listed in the

Technical sheets section of this guide.

When calculating the absorptions the

availability of current as a function

of the length of the BUS cable must

also be considered. During the sizing

therefore respect the following rules:

 the connection between the power

supply and the furthest device

must not be more than 250 m long;

MAXIMUM DISTANCES OF THE BUS CABLE

 the total length of the connections

must not be more than 500m;

 for best division of the currents

on the BUS line the power supply

should be installed in the middle.

With power supply E46ADCN:

A = 250 m max

B = 250 m max

A + B =500 m

Maximum current supplied

by the power supply: 1200 mA.

With power supply E49:

A = 250 m max

B = 250 m max

A + B =500 m

Maximum current supplied

by the power supply: 600 mA.

NOTE: If a UTP5 cable is used instead of a BUS L4669 cable, distances must halved.
