The junction box is used to connect the damper's servomotor cable to the "RG" connecting cable. When there are two dampers (air inlet and outlet),
the two servomotor cables are connected in parallel. Wire the equipment (see diagram below) according to the configuration - one or two dampers.

Once this wiring has been completed, shut-off damper side, wire the equipment electronic board side.
To ensure that the junction box is leaktight, thread the "RG" cable through one of the right-hand cable glands PG9, located under the junction box.
Connect the two "red and black" strands in the "RG" cable to the two terminals of connector "1". See diagram below:
Caution:
the strand
must be connected to the +24V and the strand
