CONNECTION TO POWER MAINS
For connection of the fan with a power cable and no adapter, follow the wiring diagram in fig. 6.
The models KSA 100/125/150/160/200 are equipped with integrated motor overheating protection and
require no extra protection measures.
ATTTENTION! The KSA 250, KSA 315 models with a power cable and no adapter have no
overheating protection!
The recommended wiring diagram for the KSA 250 and KSA 315 fan with motor overheating protection
are shown in fig. 7.
The terminals TW1, TW2 are the electrical leads of the normally closed contact of the motor overheating
protection. Connect the contact in series to power circuit of the magnetic starter coil KM1 that starts the
motor after pressing the button S1. After the motor overheating the contact gets broken and switches the
starter coil off to cut power off and stop the motor.
The automatic circuit breaker QF, the magnetic starter KM1, the control knobs S1 and S2 are not included
into the delivery set and must be installed by the users.
