Electric Connection
The requirements of the local energy supply company
as well as installation requirements specific for each
unit must be observed.
Terminal boxes on the unit
The corresponding power fuse
in the power supply line to the
switching unit must comply
with the valid requirements.
The connections in the termi-
nal box are to be connected
with the corresponding switch-
ing unit (accessory).
AG = Outside air intake grille
FK = Filter box for mixed-air box
MLK = Mixed-air box
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.
