3.6.1 - Recommendations for connecting the
system to the power supply
3.6.2 - Connecting the Pilot to the power supply
Note :
See the electrical wiring diagram in the Appendix
Check :
• The input current
• Number and thickness of power supply
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 in effect in the country of use.
This CE-approved unit complies with all the essential requirements
of the following directives:
- Low voltage n°2006/95/CE
- Electromagnetic compatibility n° 2004/108/CE
Ensure that the installation is equipped with a properly sized and
connected grounding cable.
Ensure that the voltage and frequency of the general power
supply fits requirements.
The acceptable variation in voltage is:
230 V -10% to +6% 50Hz for single-phase + Ground models
400 V -10% to +6% 50Hz for three-phase + N Ground models
The Pilot must be protected from upstream by a combined all-
pole contact (minimum distance of separation of the contacts =
3mm : EN 60 335-1) with fuses or by a magnetic thermal circuit
breaker which is calibrated based on the power of the Pilot.

Pilot is delivered pre-configured for
400V three-phase operation.
For 230V single-phase operation, you must
place a bridge (delivered in a bag) between the 3
phase terminals. See the diagram below :
