Danger
• All electrical connections must be carried out by an authorized installer and in accordance with local rules
and regulations.
Before initial operation, check the following:
• Electrical connection has been properly completed.
• Protective earth has been connected.
• Safety devices in place (protection grid).
• Leftover installation materials and foreign materials have been removed from the casing.
Testing the installation:
• Adjustment may be required in the electrical compartment during test (i.e. changing of the potentiometer), however
during operation the lid must be closed.
When putting into operation, check the following:
• Connection data corresponds to the specifications on the nameplate: Maximum v6%, -10%, according to IEC
38. Rated current must not be exceeded with more than 5% at rated voltage.
• The direction of rotation should correspond to direction-of-rotation arrow (3 phase).
• Smoothness of motor operation, (no abnormal noises).
Sound levels exceeding 70 dB(A) may occur depending on size (see www.systemair.com for detailed information).
4.5 Alarm output
The fan motor has built in protection for locked rotor, which implies that the motor tries to restart with a pre-pro-
grammed interval whenever it senses that the rotor is standing still. When the blockage is removed the fan will start up
by itself without any further measures. At high motor temperatures the current will be cut from the motor. It can then
only be restarted by manually disconnecting the mains supply to the fan for couple of minutes.
TFC 225 and TFC 280 has Tacho output
The tacho output is an open collector output. Connect a pull up resistor to a DC voltage – make sure that the current
does not exceed 10mA.
