5.2 Connection
All equipment which is connected to the controller must comply with
the following standards:
•
EN 60 742
(or other applicable safety standard) for air handlers
which provide ELV-type power supply (normally 24 V AC) to the
controller and other connected equipment.
•
EN 61 010
or
IEC 950
(or other applicable safety standard) for
computers, modems and other equipment supplied by 230 V
mains.
If equipment using 230 V mains is connected to a relay output
terminal of the controller, low-voltage equipment connected to other
relay terminals of the controller must then have at least basic
insulation to all touchable parts.
There should be a switch in order to break the power to the controller.
It does not have to be a separate switch for the controller, instead it
can also cut the supply voltage to the installation. The function of the
switch should be marked clearly.
!
WARNING!
All power supply cables should be installed by
authorised electricians.
Connect the wires to the controller as shown in the circuit diagrams.
