22 CTC EcoPart XL
General
5. Electrical installation
Installation and switching in the heat pump shall be carried out by a qualified
electrician. All wiring should follow current regulations.
The communication cable used is an LiYCY (TP), which is a 4-conductor
shielded cable, where the communication conductors are twisted pairs.
Using another cable will mean that the colours of the conductors may not
match, so you need to check that the colours of the conductors from unit 1
are connected to the same colours on unit 2.
Power supply
The CTC EcoPart XL must be connected to 400 V 3N ~ 50 Hz and
protective earth. The minimum group fuse size is shown in the rated current
column under Technical data.
Safety switch
The installation shall be preceded by an all-pole safety switch which ensures
disconnection from all electrical power sources.
Connection
The connection to the CTC EcoPart XL is made with a 5-conductor cable
that supplies the heat pump with electric power.
