Use PTFE tape, an adhesive, or fibre or
rubber joints to seal according to the type
of connection. Oakum is formally
prohibited.
Electrical connection
Any electrical work (connection, wiring etc.) should be performed with the power off and by
authorised personnel.
If the cable is damaged, it must be replaced.
All wiring on site must be consistent with the standard NF C15-100 in France or the legal standards in
force in the country concerned (for example IEC 60204/IEC 60335). It is recommended to make a different
and separate cable pass from the refrigerant and hydraulic pipe passages. Similarly, it is recommended
to separate the electrical cables of power, control, signalling and communication.
The chiller’s supply voltage is three-phase + neutral 400V 50 Hz. The sizing of the connection cables
(power, control)
is the installer’s responsibility. This must take into account, in addition to the information
on the data plate, the regulations of the country where the product is installed.
When changing components, ensure continuity of grounding as well as commissioning.
Since the Chiller is composed of two variable speed drives, it is preferable to use a Class B differential
circuit breaker for the power supply.
