Unit heaters with 2-stage three-phase motor / Unit heaters with 1-stage single-phase motor
Installation and operating instructions
8.5 Single-phase motor
The fan motors (230 V/50 Hz) are equipped with a single-phase winding
with capacitor auxiliary phase. The speed can be reduced with a 7-stage
single-phase controller by reducing the voltage.
Electrical wiring of a single-phase motor
The fan motor has a 230 V main winding with capacitor auxiliary
winding. The units are factory-wired to the correct direction of rotation
(wiring diagram 1).
If there is no air output then it means that the direction of rotation is
incorrectly wired!
Parallel connection of single-phase motors
The parallel connection of several TIP units, even of different sizes, to a
single stage switch is possible up to the maximum switching capacity of
the stage switch. If several TIP unit heaters are connected to a single-
phase controller, we recommend the use of intermediate terminal boxes.
Important:
Switch the thermal contacts of all fan motors in series!
Important:
Switch the motor windings of all fans in parallel!
Suitable single-phase switching units
Different switches from our range are available to switch and control
the speed of the motors. The table at the top of page 18 provides an
overview of the switches used, their switching power and the resulting
max. number of TIP units that can be connected to a switch.
