2.3 Power supply of the hood
pic. 14
- The Ultravent must electrically be connected in
accordance with the local regulations.
Before removing the plug or reconnecting to the
power supply, ensure that the operating switch is
in the "off” position.
- The Ultravent is delivered with power cord. The
terminals for power connection can be found in
the power box at the rear side of the Ultravent.
The color code of the terminals are:
PE = earth yellow/green (ground)
L = phase grey
N = neutral blue
- Also on the rear side of the hood there is an earth
connection stud. Fit the hood with a suitable cable
to the earth bonding (ground) system
2.4 The combination of Rational Combi and Ultra-
vent is electrically interlocked. The Combi shall
only operate under the following conditions:
a) The UV must be electrically switched "ON”
b) All filters (charcoal filter and fat filter) must be
correctly installed. This is controlled by ad-
ditional reed switches.
c) Charcoal filters must be clean
To connect this circuit proceed as follows:
pic 15
1. There is an extra interface pcb (A8) delivered with
the Ultravent kit. Fix it to the electrical mounting
plate of the combi at a suitable position.
2. In the kit also cable W24 (pic 1 item 9) is sup-
plied. Connect this cable to X23.1 of the interface
pcb (A8).
3. Run this cable W24 out of the electric compart-
ment through the cable gland back up to the
power box of the Ultravent. Connect brown wire
to terminal 4 and black wire to terminal 5 of the
power box.
