Control voltage supply Uc
CAUTION!
– Before connecting, ensure that the mains voltage corresponds with the control voltage of the
unit (230 V/1 50…60 Hz).
– The humidifier must only be connected to a mains supply with a protective conductor .
The connection to the control voltage Uc is made in accordance with the wiring diagram, to the ter-
minal “X3” on the power board. The customer is to install a service switch Q3 in the supply line
(all pole disconnecting device with a minimum contact opening of 3 mm) and an F3 fuse (max. 10
A slow acting) (these are both essential requirements).
The cross-section of the mains cable must comply with the applicable local regulations (minimum
of 1.5 mm
2
).
External safety circuit
To guarantee the safety of the humidification system, monitoring the operation by means of a safety
circuit is an absolute requirement.
To accomplish this, the
potential-free contacts (max. contact loading 250V/5A) of external moni-
t or ing devices (e.g. safety high limit humidistat, airflow monitor, ventilation interlock, etc.) are con-
nected in series to the contacts “SC1” and “SC2” of the terminal block “X3”
in accordance
with the wiring diagram.
DANGER! Danger of electric hazard!
The mains voltage is connected to terminal block “X3” (up to 240 V). The steam humidifier must
therefore be isolated from the mains supply (heating and control voltage), before starting the con -
nection work.
If, for whatever reason, no external monitoring devices are connected, a connecting bridge “J” must
be installed on the contacts “SC1” and “SC2” of the terminal block “X3”.
Do not apply any
extraneous voltage to the terminals.
The cross-section of the cable must comply with the applicable local regulations (minimum of 1 mm
2
).
Remote operating and fault indication H1 (Option “RFI”)
The optional remote operating and fault indication PCB is to be connected to the control board via
the terminal “J1”. The optional remote operating and fault indication PCB contains four potential-free
relay contacts for the connection of the following operating and fault indications:
– “Error”:
This relay is activated if an error is present.
– “Service”: This relay is activated when the set service interval has expired.
– “Steam”: This relay closes as soon as the unit produces steam.
– “Unit On”: This relay closes as soon as the unit is switched on via the main switch.
The maximum contact loading is 250V/5A .
Appropriate suppressor modules are to be used for the switching of relays and miniature contac -
tors.
Note: The minimum cross section of the supply cable must comply with the local regulations.
