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).
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.
Initial Operation
Prior to initial operation
1. Check that assembly is mechanically sound.
2. Check that the connection to the customer-installed
heating system is correct.
3. Make sure that hot surfaces are protected against
unintentional contact.
4. Ensure that the unit’s electrical wiring has been
made in accordance with the relevant guidelines
and standards and complies with the enclosed wir-
ing diagrams.
5. Check the fan area as well as the air intake and
outlet area for foreign objects.
6. Make sure that all air outlet openings are opened.
7. Ensure that the distance between the fan wheel and
housing is the same all the way around.
8. Activate the power supply to the switching unit and
switch the unit on via the control switch.
9. Check to make sure that the fan is rotating in the di-
rection of the arrow.
The rotational direction can be changed by revers-
ing the 2 phases.
10. Remember that when using speed control, the ca-
pacity of the regulating unit must be adjusted to the
capacity of the motor.
11. Initial operation is prohibited until it is ensured that
the proper assembly and electrical installation cor-
responds to the provisions of the EU guidelines
89/392/EWG and 73/23/EWG.
During initial operation
All regulating, control and safety mechanisms must be
checked to ensure that they are functioning properly
and set correctly during initial operation.
1. Measure the power consumption of the fan.
The rated current may not exceed the value speci-
fied on the type plate in each switching phase.
2. Check the control/regulating function of the fan.
3. Check the motor protection function of the fan.
4. Check the function of the frost protection mecha-
nism and the room thermostat
If mounted.
5. Check that the fan is running quietly.
6. Check the entire system for any vibrations.
7. Check that the heating medium supply lines have
been properly connected and are impermeable.
The control switch must always be reset to “0” to
restart the unit after the switching unit is sepa-
rated from the power supply, following a power
outage or a malfunction.
