The power supply cable must fulfil the following requirements:
W
Cable socket: 5-pin, 7/8"
W
Cable cross-section: per wire ≥ 0.5 mm
2
W
Length: max. 20 m
A standard power pack can supply all system components with
24 V. Both 0 V connections must be connected.
Since the orientation of the 7/8" plug cannot be guaranteed,
this must be taken into special account when using an
angled plug.
5.3.5 Connecting the bus coupler logic
and load supply
Power is supplied to the valves and the bus coupler via the
X10 (POWER) plug.

CAUTION
Dangerous voltages
A power pack without safe isolation may lead to dangerous
voltages in the case of a fault. This may damage the system
and cause injuries arising from electric shock.
O
Only use a power pack with safe isolation according to
EN60747, VDE 0551 classification! The corresponding
electrical circuits are thus SELV/PELV circuits in
accordance with IEC 60364-4-41.
