5.5.3 - Recommendations for connecting the
system to the power supply
Check:
• The power consumption
• Number and thickness of the 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
regulation in eff ect 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 fi ts requirements.
The acceptable variation in voltage is:
230 V -10% to +6% 50Hz for single-phase + Ground models.
5.5.4 - Connection to the power supply
The HTi
70
Heat pump is CE-marked. It is compliant with French
standard NF C15-100 as well as European standards EN 61000-3-3
and EN 61000-3-11, among others.
The power supply cable should be sized carefully according to the
following factors:
- Maximum current required
- Distance between the HTi
70
Heat pump and the power
supply
- Overall protection
- The neutral operating system
Make sure to strip the cable before placing it into the
terminals, and make sure that the copper is in good
condition.
A method of disconnection must always be installed in
compliance with the installation rules.
If the power supply cable is damaged, it must be replaced by a
qualifi ed professional to avoid any risk of danger.
To access the terminals: remove the panel on the right-hand side
(2 screws) and the front panel (4 screws) and open the electrical
box (4 screws).

The information given here is for information purposes only. It must be verifi ed and adapted if needed based
on the installation conditions, and on the standards in eff ect.
If cable length exceeds 15m or if the network is subject to drops in voltage over 10V, use a cable with a
larger width.

Connecting terminals
The terminal strips are spring-loaded «Cage
Clamps».
For Handling, use the following :
- for 2.5mm² or 4mm² control terminals, use a
3.5 x 0.5mm fl at-head screwdriver.
- for 6mm² power terminal, use a 5.5 x 0.8mm
fl at-head screwdriver.
1
: Insert the screwdriver into the rectangular
window located on top of the terminal block.
2
: Insert the wire ito the «Cage Clamp» when the
fl ap is open.
3
: Remove the screwdriver.
Nota :
The wires must be stripped to the following lengths :
- for the 2.5mm² control terminals between 8 and 10mm.
- for the 4mm² control terminals between 10 and 12mm.
- fort the 6mm² power therminal between 13 and 15mm.
