Restriction of guarantee!
Non-compliance with the relative legal requirements,
operating instructions and unit-specific wiring diagrams
can lead to malfunctions that cause damage.
In cases of non-compliance, the guarantee becomes null
and void
!
The electrical connection may only be made by
trained and authorised personnel.
Connecting several units
If necessary, several units (even of different sizes) can
be operated at the same time via a switching unit
(accessory).
The overall capacity of the connected units may not,
however, exceed the maximum electrical capacity of the
corresponding switching unit.
For thermal motor protection, the thermal contacts of all
motors are to be connected in a row. Follow the sepa-
rate wiring diagrams.
There can never be more than one external regulating
mechanism per switching unit (thermostat, day/night
regulator, etc.) connected at a single time!
Connecting the units
Standard REMKO PWW models are equipped with ax-
ial fans that have external rotary current motors for a
voltage of 400 V / 3~ / 50 Hz.
Switching the two speeds of the rotary current motor is
done with a Y /
∆ switch.
Integrated thermal contacts protect the motor. They
switch off the fan motor at a winding temperature of
130 °C in connection with a suitable switching device
(accessory).
The rotary current motors are connected to the corre-
sponding switching units in accordance with the respec-
tive electrical wiring diagrams.
