Installation and heat pump connection must be performed by
an authorised electrician. All wiring must be installed according
to applicable provisions. Before the front panel is opened or
other live components are made accessible, the power supply
to the heat pump must be fully disconnected.
6.1 Electric installation 400 V 3N~
CTC EcoPart 600M must be connected to 400 V 3N~ 50 Hz with protective
earth.
The 2 meter long feed cable is fully wired in the heat pump and is routed via
the terminal box X1 on the left rear.
6.1.1 Omnipolar safety switch
The installation should be preceded by an omnipolar safety switch according
to overvoltage category III, which ensures disconnection from all electric
power sources.
The EcoPart 600M should be equipped with a faulty residual current switch
with delayed deactivation.
6.1.2 Alarm output
The CTC EcoPart 600M is fitted with a potential-free alarm output which
is activated if any alarm is active in the heat pump. This output may be
connected to a maximum load of 1 A 250 V AC. An external fuse should also
be used. A cable approved for 230 V AC must be used for connecting this
output, irrespective of the load that is connected. For connection, see the
section entitled Wiring diagram.
