Electrical Connection
The electrical connection of the flow monitor is via the connector plug. The switch contacts em-
ployed in these devices are potential free and do not require a power source. Switch contacts and
flow monitor have been optimally harmonized. After replacement of a switch contact, the switch
point must be readjusted.
Attention:
Prior to the electrical connection of the device, it must be ensured that the supply voltage
matches that required and the supply voltage is switched off.
