Notes on electrical installation
All work concerning the electric installation must be performed only by adequately qualified
personnel (electrician or workman with equivalent training).
Ascertaining the qualifications is the
customer‘s responsibility.
Observe all
local regulations
concerning the electric installation.
Warning - danger of electric shock! The steam humidifier may be connected to electric
mains only after all installation work has been completed.
Attention!
The electronic parts inside the humidifier are very sensitive to electrostatic discharge.
To prevent damage,
appropriate measures against electrostatic discharge (ESD protection)
must be taken when carrying out installation work.
Please observe the following installation notes regarding the electrical installation:
–
Primary wiring
Humidifiers require field wiring to primary voltage terminal blocks. Power requirement is 220…240V/50…
60Hz, 16 A slowacting fused (“
F1
”) circuit, single phase. Wiring is fed through a 22 mm hole in the
bottom of the control compartment. Installation of
external service switch “Q”
(all pole disconnect
ing device with a minimum contact opening of 3 mm)
is mandatory
.
The service switch “Q” must
be mounted in the separate compartment outside the unit, above the electrical service door
.
When installed, the appliance
must be electrically grounded in accordance with local codes,
if an external electrical source is utilized.
Connect ground wire to cabinet ground clamp.
External wiring sizes must be in accordance with existing local electrical codes and bylaws.
–
Remote operation and fault indication
The remote operation and fault indication board is equipped with 4 relays for remote operation and
fault indication.
– “On”:
this relay closes after the humidifier has been powered up
– “Steam”: this relay closes as soon as steam is produced
– “Service”: this relay closes when the set maintenance interval has expired
– “Error”:
this relay closes when an error occurs
–
External safety circuit (
K1
)
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 potentialfree contacts (250V/2A) of exter
nal moni tor ing devices (B1: safety high limit humidistat, B2: airflow monitor, B3: ventilation interlock,
etc.) are connected in series to
terminals 1 and 2
.
–
Control or sensor signal
The signal line (signal Y) is connected to
terminals 3 and 4
. The signal line (signal Z) is connected
to
terminals 3 and 5
. By default the Condair GS is configured for a 0…10 VDC control signals.
The control signal type can be modified via the software (see menu “user settings”, in the operating
instructions for the Condair GS control). The configuration whether the Condair GS is controlled via
the internal or via an external controller is also done via the software.
