wiring diagrams, see Fig. 11 on page 20, and the wiring diagram in the terminal
box.
• The motor is fitted with a bimetal temperature monitoring switch (potential-free
thermal contact, 230 V AC, 300 mA). Wire the motor so that it is de-energized
when the switch is triggered.
• Insert the cable so that it cannot get damaged during operation.
