If motor overheat protection is specified, terminals
T1 and T2 must be connected to the fan control circuit.
Failure to do this will invalidate the warranty.

Single phase.
Three phase - up to and including 3kW.
Three phase - 4kW and above.
Important.
T1 and T2 = Thermistor connections
H1 and H2 = A.C. Heater connections
For good EMC engineering practice, any sensor cables
or switched live cables should not be
placed within 50mm of other cables or on the same
metal cable tray as other cables.
4.0 Electrical Installation
Units are not supplied with electrical isolators, their
selection and provision is the responsibility of the installer.
Ensure the electrical supply is suitable for the fan and that
all wiring, fuse and overload protection etc is appropriately
sized by comparing with the rating plate.
Electrical connection is made direct to the motor terminal box.
For DOL starting of 4kW and above, 3ph, the final
connection must be in DELTA. If a STAR/DELTA starter
is to be used connect all six motor terminals to the
appropriate terminals of the starter.
Isolation - Before commencing inspection or
maintenance work make sure that the unit
is electrically isolated from the mains supply.
