3.5.2.1 - Pilot: 230V single phase connection
3.5.1 - Recommendations for connecting the
system to the power supply
3.5.2 - Connecting the Pilot to the power
supply
Check:
• The input current
• The number and thickness of power cables
• Fuse or circuit breaker ratings
The power supply must come from an electrical protection
and sectioning device which complies with all current rules
and regulations. This CE-stamped appliance complies with the
essential requirements of the following directives:
- Low voltage n°2006/95/CE
- EMC n° 2004/108/CE
Check the the installation is equipped with a correctly sized and
connected ground cable.
Check that the voltage and frequency of the general power
supply fi t requirements. The amount of variation in voltage
permitted is:
230 V -10% à +6% 50Hz for single phase models + ground cable
400 V -10% à +6% 50Hz for three-phase models + neutral + earth
cable.
The Pilot must be protected beforehand by an
all-pole circuit
breaker
(minimal distance to separate contacts = 3mm: EN 60
335-1) using either fuses or a thermal magnetic circuit breaker
calibrated to the right power for the Pilot.
To access the terminals,
remove the front
faceplate of the Pilot
and open the control
box
3 control terminals on
the electronics board:
- 12 point (HP/HC; DEL;
Amb2; Amb1; Pixc; Ext)
- 2 point (shielded
connection)
- 2 point (Chaud)
