Installation
In event of high risk of electric storms (lightning) or when
liquid medium in well or tank or sump is very dirty it is
recommended that a oat switch is used.
CAUTION
If the oat switch has three wires, use Black and Brown wires.
If the oat switch has different colors, use a multimeter to
identify connections as follows: Low Level - no reading [OFF],
CAUTION
High Level - positive reading [ON]
Do not enclose sensor leads, oat switch wires or signal
cables within metal pipes, instead use PVC or PE tubing.
CAUTION
4.5 Installation of Temperature Sensor
To connect the temperature sensor, the motor must have a thermal switch embedded in
the motor windings. Connect the thermal switch with the NC (normally closed) contact.
If the motor doesn't have a thermal switch, the terminals 9, 10 and 10, 12 should be
connected using two jumpers.
