4.3.6 - Connection of the digital inputs (Di)

This is a volt-free contact for any parameter setting.
Digital inputs 1 are wired to connector J2, and digital
inputs 2 are wired to connector Q11. The maximum length
of the contact loop is 30 m.

Operating principle of connector Q11:
1 Push on the white part to open the connecting hole.
This is not necessary, if the wire is single-strand or
tinned.
2 Insert the stripped cable (max. 7 mm) by pushing it
into the hole.
3 Release the white part and pull lightly on the cable to
ensure that the connection has been made.

4.3.8 - Controller supply

The controller supply is from the network:
230 V a.c. (± 10 %) 50 Hz or 60 Hz.
The network wiring connection is made to the disconnect
device integrated into chilled beam 1 (with mother board
and daughter board).
The connection cable section must be calculated, based on
the maximum capacity of the chilled beam to which the
controller is connected. The quality and the installation
must comply with the recommendations of standard IEC
60364.
CONNECTION TO THE PROTECTION CIRCuIT
(EARTH): The earth supply cable ensures the continuity of
the protection circuit. It must always be connected at the
earth terminal provided.
