3.5 Power wiring
Make sure that the protection circuit is open before making the
connection to the mains.
Check that the power supply voltage to be connected matches the value
indicated on the rating plate inside the electrical panel.
Insert the power and ground connection cables into the electrical
panel compartment using the strain reliefs supplied, and connect to the
terminals. An external fused disconnect must be installed. See Fig. 3.o
All wiring must be in accordance with local, state and national electric
codes.
NOTE: to avoid unwanted interference, the power cables should be kept
separate from any control wiring.
NOTE: Tolerance allowed on main voltage =-15% to +10%.
Connect power wires to the power terminal. See Fig. 3.p

3.6 Control wiring
On compactSteam XL, steam production is controlled by an external
signal:
• in on/off mode, a simple contact (for example a humidistat) enables/
disables steam production;
• in proportional mode, the humidifi er produces a quantity of steam that
is directly proportional to the 0 to 10 V signal generated by an external
control device.
The compactSteam XL unit can be connected to any simple or automatic
humidistat, as well as safety devices such as limit humidistats, air fl ow
switches and remote ON/OFF switches.
To connect the xternal control devices, run the cables through the
bottom of the unit until reaching the top of the control module, and
secure them with the cable clamp (see Fig. 3.m). Move the channel (see
fi g. 3.n) and attach to terminals (see fi g.3.o).
The terminal blocks for the control wiring are located at the top right of
the control module (see Fig. 3.o).
IMPORTANT NOTE: Select the correct type of control signal on the keypad
(see paragraph 5.1.1) before connecting the control wiring.
3.6.1 On/Off operation
The diagrams shown in the fi gures on the side indicate the connections
to be performed on the terminal
block in the following situations:
Fig 3.p operation controlled by a simple voltage-free remote enabling
contact, indicated as CR;
Fig 3.q operation controlled by an external mechanical humidistat,
indicated as H;
Fig 3.u a combination of the above.
Remote enabling contact (fi g.3.p)
Remove the jumper between terminals AB-AB and connect the voltage-
free remote contact (CR) in series to terminals AB-AB; terminals IN-GND
must be jumpered.
When contact AB-AB is closed, the humidifi er is enabled for operation; if
the contact is open, steam production stops immediately.
External humidistat without enabling (fi g. 3.q)
Connect the external humidistat between terminals IN-GND and leave
the jumper in position between terminals AB-AB.
If the IN-GND contact is closed, steam production starts, while if it is open
steam production stops after 5 s.
