“Utilities powered at diff erent voltages (only 12/24V)”
The humidifi er activates but does not supply power to the utilities. The
utilities are thus powered externally and at diff erent voltages.
Procedure:
1.
remove the terminal block (2 pieces) from connector B and
disconnect the L, N cables;
Insert the terminal block supplied (code 98C565P018) into
connector B and reconnect the cables, L (terminal 1) & N (terminal 8);
2.
jumper terminals AP1 and AP2;
3.
insert the terminal block supplied (code 98C565P012) into connector
A and connect the utilities (see the following fi gure).
Note:
•
maximum load for each utility: 2 A;
•
AP1 and AP2 are protected by 6.3 A fuses;
•
the utilities must be suitably protected against overloads and short-
circuits.

Final checks
the rated voltage of the appliance corresponds to the rated supply
voltage;
the fuses installed are suitable for the line and the power supply
voltage;
a mains disconnect switch has been installed to disconnect power to
the humidifi er when required;
the humidifi er has been correctly earthed;
the power cable is fastened using the tear-proof cable gland;
terminals M2.7 and M2.8 are connected by jumper or connected to an
enable-operation contact;
if non-CAREL probes are used: the earth of the probes is electrically
connected to the humidifi er board earth;
if the humidifi er is controlled by an external control device, the earth
of the signal is electrically connected to the controller earth.
Types of utility connection
“Utilities powered at the same voltage”
The humidifi er supplies power to and activates the utilities connected
at the same voltage. This is done by applying a 12 V, 24 V or 230 V power
supply to terminals AP1 and AP2.
Procedure:
insert the terminal block supplied (code 98C565P012) into connector A
and connect the utilities (see the following fi gure).
Note:
•
maximum load for each utility: 2 A;
•
AP1 and AP2 are protected by 6.3 A fuses.
