Mounting instructions
Speed controller for single phase voltage
controllable motors.
Technical data
Voltage 230 Vac - 50 Hz
Current range Fuse: see page 1
Enclosure: plastic R-ABS, UL94-V0, grey RAL
7035
Max ambient temperature: 35 °C
These transformer speed controllers are based
on the principle of voltage control with auto-
transformers. They are applicable to voltage-
controllable motors (230 V - 50/60 Hz) to
control the speed (of fans, pumps, etc.).
When choosing a controller it is important to
know the current intensity consumption on
the taps. This max. should be limited and not
been exceeded!
Mounting
The controllers are to be mounted on a smooth
surface. Connect voltage supply, motor(s) and
earth as shown in the scheme with cables of
the proper diameter. On the mains side, a sa-
fety switch with recommended pre-fuses has
to be installed.
Standard configuration is
1:Grey:110, 2: violet:140, 3: orange: 170,
4: brown:190, 5: red:230V.
Output voltages can be reconfigured by re-
plugon of the fastons on the PCB.
Warranty
Two years from delivery date against defects
in manufacturing. Any modifications or altera-
tions to the product relieve the manufacturer
of all responsibility. The manufacturer bears no
responsibility for any misprints or mistakes in
this data, and modifications or improvements
to the product can be made at any time after
date of publication.
Transport and stock keeping
Avoid shocks. Stock In original packaging.
Avoid extreme conditions
Maintenance
In normal conditions the controllers are mainte-
nance-free. If soiled clean with dry or dampish
cloth. In case of heavy pollution clean with a
non-aggressive product. In these circumstances
the controller should be disconnected from the
mains. Pay attention that no fluids enter the
controller. Only reconnect the controller to the
mains when it is completely dry.
Motor protection
It is always recommended to install a proper
motor protection device.
All works may only be carried out by skilled
personnel following the local regulations and
AFTER the controller is completely separated
from the mains.
Replace fuse only with same type and rating.
