2.3.1 Electrical specifications
The cross-section of the supply cable must be carefully selected based on:
- the maximum current of the unit and the electric heating element
- the distance between the domestic electrics box and the GeoCIAT
TM
Modular
- the room temperature
- the upstream protection and the neutral operating conditions
(1) Cable with 3 or 5 conductors for temperatures below 70°C and for a maximum length of 30 m
(2) Cable with 3 or 5 conductors for temperatures below 90°C and for a maximum length of 30 m
Note: all connections must be wired in compliance with the regulations that apply to the location where the system is installed (e.g.
NF C 15 -100 in France) and are under the responsibility of the installer. Failure to comply with the requirements of the above
standards will invalidate the CIAT warranty.
For terminal J45, the tightening torque must be at least 0.6 Nm.
To be added as an option
(e.g. 4kW GeoCIAT
