8.6 230 V electrical connection
• The two internal EC fans of the ventilation unit
are supplied with 12 V DC and activated using
a PWM signal (0 – 5 V).
• The power supply for the ventilation units is
provided by the room air control for up to 6 fans
(up to 3 PPB 30).
• The room air control is supplied with 230 V AC.
• The unit variant PPB 30 RC has a fully integ-
rated control unit with 230 V connection.
Note the following safety instructions.
DANGER Danger of electric shock.
Before installing the electrics, shut down all sup-
ply circuits, switch off mains fuse, secure against
being accidentally switched back on and position
a visible warning sign. During operation, the
board cover and front cover of the internal hous-
ing must be mounted.
WARNING Danger of burns/fire due to
overload caused by incorrect connection or
connecting too many units to a RLS 45 O /
RLS 45 K.
Connect units in accordance with connection dia-
gram. Observe permissible number of ventilation
units per room air control/power unit.
WARNING Danger of electric shock if the
12 V low voltage and 230 V are not disconnec-
ted or are insufficiently disconnected.
Ensure a safety distance between 230 V and 12
V cables. Ensure minimum distance of 8 mm.
WARNING Danger of electric shock if the
connection on the 230 V input of the PP 45 RC
units and the RLS 45 O / RLS 45 K controller
is incorrect.
Ensure a phase balance between all components
connected to the ventilation system.
WARNING Danger of electric shock if the
RLS 45 O / RLS 45 K control is installed within
the protection zone.
No IP protection present (IP 00). The room air
control may only be installed outside protective
zones 0, 1 or 2.
