MOUNTING INSTRUCTIONS IN STEPS
Before you start mounting the TCMF8-DM, read carefully “Safety and Precautions”
and follow these steps. Choose a smooth solid wall surface for installation.
Follow these steps:
1. Switch OFF the main power supply.
2. Unscrew the front cover and open the enclosure. Mind the wires that connect the
potentiometer with the printed circuit board.
3. Fix the unit onto the wall or panel using the provided screws and dowels. Mind the
correct mounting position and unit mounting dimensions. (See Fig. 1 Mounting
dimensions and Fig. 2 Mounting position.)
4. Pay attention to the following instructions in order to minimize the operating
temperature:
►Respect the distances both between the wall / ceiling and the device and
between two devices as shown in Fig. 2. In order to ensure sufficient ventilation
of the controller, clearance on every side has to be maintained.
►When installing the device, please keep in mind that the higher you install it,
the warmer the device will get. For example, in a technical room the correct
installation height can be of great importance.
5. Insert the cables through the cable glands and do the wiring according to the
wiring diagram (see “Wiring and connections“) while adhering to the information
from section “Wiring and connections”.
►Connect the AC fans (terminals U2, U1 and PE);
►Connect the supply voltage (terminals L, N and PE);
►Connect the sensors via the RJ45 socket or via the Modbus terminal block.
►If applicable, connect the analogue input signal(s)
6. Put back the cover and secure it with the screws. Tighten the cable glands.
7. Switch on the power supply.
8. Connect your installation to SenteraWeb and download the required application
specific firmware.
9. Switch ON the main supply after all connections are done and checked.
*Not respecting the above listed rules can reduce service life and relieves the manufacturer of any responsibilities.

TCMF8-DM UNIVERSAL FAN SPEED CONTROLLER
VERIFICATION OF INSTALLATION
After connecting the unit to the main supply, the green LED on its cover should light
up to indicate that the controller is supplied.
Safe operation depends on proper installation. Before start up, ensure the following:
■e main supply is connected correctly.
■ere is sufficient air flow around the unit.
■Minimum voltage is selected based on the fan parameters - the entire fan
regulation range must be within its operating voltage.
■Maximum load current is according to the device selected, make sure the current
drawn by the fan does not exceed the current rating of the device!
■During operation, the unit must be closed.
■If the unit does not work according to the instructions, the wiring connections and
settings need to be checked.
ATTENTION Disconnect main power supply before all servicing and maintenance. High Voltage on
the internal circuit!
ATTENTION High temperatures may occur during operation. Allow to cool before maintenance!
ATTENTION Drawing excessive current from the fan controller will cause the internal circuit
to overheat and fail.
TRANSPORT AND STORAGE
Avoid shocks and extreme conditions; stock in original packing.
WARRANTY AND RESTRICTIONS
Two years from the delivery date against defects in manufacturing. Any modifications
or alterations to the product after the date of publication relieve the manufacturer
of any responsibilities. e manufacturer bears no responsibility for any misprints or
mistakes in this data.
MAINTENANCE
In normal conditions this product is maintenance-free. If soiled, clean with a dry or
damp cloth. In case of heavy pollution, clean with a non-aggressive product. In these
circumstances the unit should be disconnected from the supply. Pay attention that
no fluids enter the unit. Only reconnect it to the supply when it is completelydry.
