3.6. Electrical connections
DANGER:
Ensure that the general electrical power supply has been switched off
before starting any repair work.
CAUTION:
The protective earth conductor must be longer than the phase and neutral
conductors. Furthermore, the main earth conductor and the power supply
conductors must have a double attachment very close to their connections.
The electrical panel is located under the cover. The minimum spaces indicated in
paragraph 3.4.2 must be respected for the electrical connections.
The installer must fit a dedicated circuit breaker upstream of the electrical
connections of the appliance (main circuit breaker).
The supply voltage must be definitive and must not vary, in which case contact the
power supplier. The power supply must respect the mentioned limits, otherwise
the warranty is immediately void.
If the power cable is damaged, it must be replaced by qualified personnel, in order
to prevent any risk.
Any appliances located nearby may cause/suffer electromagnetic disturbances
to/from the unit. Be aware of this risk on the installation site. We recommend
powering the unit electrically with an adequate line and protections and to use
independent cable ducts.
The flow rate controller (item B on the above hydraulic diagram that is factory-
fitted) must ALWAYS be connected in compliance with the indications shown on
the electrical wiring diagram. Never shunt the flow rate controller connections in
the terminal block. The warranty will be void if the flow rate controller connections
are modified or connected incorrectly.
Refer to the specific instructions for the wiring of Ecomod heat pump control
3.6.1. General remarks on electrical connections
Check that the electrical power supply complies with the nominal characteristics of the appliance
(voltage, phases, frequency) as stated on the data plate located on the side panel of the appliance.
The electrical connection must comply with the electrical wiring diagram of the appliance and
local and international regulations (fit a main circuit breaker, and differential circuit breakers for
each line, and earth installation adequately, etc.).
The electrical installation must be made in accordance with regulations.
CAUTION:
All of the installation operations must be carried out when the heat pump is
stopped, and after disconnecting the electrical power supply.
These operations must only be carried out by QUALIFIED PERSONNEL.
Remove the cover without remove the cable duct support plate.
When the work is complete, refit all of the covers removed with their screws and
seals (if present).
3.6.2. Accessing the electric box
