9.1 Mounting instructions

● For WRG operation (air extraction and venti-
lation in a 60-second cycle), set up unit pairs.
● The room air control has plug-in connection
terminals, which can be taken off for wiring.
● When using more than 2 ventilation units,
we recommend installing the room air cont-
rol in an electronic switch box to be supplied
by the customer. This provides sufficient
space for the connection of the cables to the
room air control.
● Only mount internal covers on flat surfaces
and without any distortion to avoid noise.
● Prescribed connection cables,
also see wiring diagrams in appendix
Mains connection and 230 V input:

Type NYM-J 5G1, 5 mm²
Control cables: Type J-YSTY, 0.8 mm,

4 wires. Max. 25 m from star point, up to
star point max. 4 m.
● Connector plug for fan cable:

with wiring diagram.
PP 45 K PP 45 RC
or 230 V power supply in accordance with
wiring diagram in appendix. Connector plug
for fan cable is plugged onto board.
● Ventilation units may only be operated using
the voltage and frequency shown on the
rating plate. For rating plate, see RLS 45 O
or RLS 45 K control or PP 45 RC ventilation
unit. Operating voltage for PP 45 O/K units
= 12 V DC.
● The appropriate mounting material must be
supplied on site.
● Sensors: Incorrect measured values can re-
sult from unsuitable installation location. Avoid
disturbing influences and direct sunlight.
