4.4 Alarm contact (M5.1 - M5.2)
Contact available for the remote signalling of one or more alarms.
M.5.1 M.5.2
Fig. 4.l
Electrical specications: 250 Vac; Imax: 2 A resistive 2 A inductive.
Note: use clamps on the relay terminal blocks (alarm, utilities) to
prevent the cables from being detached.
4.5 Auxiliary contact: prod. request present,
external fan control) (M14.1 - M14.3)
Relay contact that indicates the presence of the steam production
request. It can also be used to control an external fan (see chap. 12.7)
M.14.1 M.14.2
M.14.3
Fig. 4.m
Electrical specications: 250 Vac; Imax: 8 A resistive 2 A inductive.
Final checks
The following conditions represent correct electrical connection:
Ƒ the rated voltage of the appliance corresponds to the rated supply
voltage;
Ƒ the fuses installed are suitable for the line and the power supply
voltage;
Ƒ a mains disconnect switch has been installed to disconnect power to
the humidier when required;
Ƒ the humidier has been correctly earthed;
Ƒ the power cable is fastened using the tear-proof cable gland;
Ƒ terminals M2.4 and M2.5 are jumpered or connected to an enable-
operation contact;
Ƒ if the humidier is controlled by an external control device, the earth
of the signal is electrically connected to the controller earth.
5. REMOTE TERMINAL AND SUPERVISORY NETWORK
5.1 Remote display terminal
The display terminal can be detached from the humidier and moved up
to 30 m (98 feet) away.

/ 98 feet distance);
2 two EMC lters (code 0907858AXX) to be applied to the ends of the
telephone cable;
3 remote display terminal.
Note: to ll the empty space left by the display terminal on the
humidier, use CAREL kit code HCTREW0000.

For lengths greater than 10 m (33 ft) use shielded cable with the shield
connected to PE both on the terminal side and the controller side

Important: for the RS485 connections in household (IEC EN
55014-1) and residential (IEC EN 61000-6-3) environments, use
shielded cable (with shield connected to PE both on the terminal side
and the controller side) with maximum shielded cable length: specied
by the EIA RS485 protocol, equivalent to European stan-dard CCITT V11,
using shielded twisted pair cable, AWG26, 485 input stage impedance
1/8 unit-load (with this conguration, a maximum of 256 devices can be
connected) laid in separate conduits from the power cables.
