ELECTRICAL CONNECTIONS
- Before working on the controller, disconnect the power supply and ensure it cannot be reconnected! Check that there
is no power!
- Electrical connections must be made only by an expert service technician, and in accordance with pertinent regula-
tions and standards. Do not use the controller if there are visible signs of damage on the housing.
- Low voltage cables must be routed separately from mains voltage cables. Feed temperature sensor cables only into
the left hand side of the controller, and mains voltage cables only into the right hand side.
- The user must install a device capable of disconnecting all poles, such as a thermal magnetic breaker.
- Cables connected to the controller must be stripped by no more than 55 mm, and the cable jacket must extend into the
housing to a point just beyond the strain relief gland.
- The controller and the Vortex Flow Sensor must have the same ground potential. The VFS has a functional earth connec-
tion (PELV). The PE output of the controller must be connected to the pipe system at a point near the sensor.
