Wiring

Open the device by loosening the four screws on the front to gain access to the ports for the
power supply, for the sensors, etc. First, lead the cables for the power supply through the cable
gland provided for this purpose and establish the power supply via the DC+ and DC- connections.
Ensure correct polarity. Then connect the inlet sensor and the outlet sensor to the corresponding
ports. For more information on the connection labels, refer to the following chart. When
connecting, make absolutely sure that there is no voltage.
