Cable bushing
Use the cable trays located on the top left of the
rear jacket (see
) to introduce the connection
cables:
• The
upper
tray must be reserved for the
power
connections
(boiler power supply, alarm feedback
or circulating pump control).
• The
lower
tray is dedicated to
signal connections
(sensors, communication bus, etc).
Use the cable clamps (not shown) at the entrance
to the cable trays to block the cables mechanically.
For the connection of the general power supply,
comply with the wiring diagram, in particular the
phase, neutral and earth polarities.
