3.3 Electrical connection

• By authorized and qualified specialized personnel only.

• When the device is connected, national and international electrotechnical

regulations must be observed.

• Disconnect the system from the mains before electrically connecting the

device.

• Do not connect the device when it is live.

Depending on the version, a different PCB terminal is fitted. All versions except
Modbus have analogue output.
