Connecting the device

•

When using the measuring device in hazardous areas, installation must comply with 

the corresponding national standards and regulations and the Safety Instructions or 

Installation or Control Drawings.

•

A suitable circuit breaker has to be provided for the device in accordance with 

IEC/EN 61010.

•

Devices with integrated overvoltage protection must be earthed.

•

Protective circuits against reverse polarity, HF influences and overvoltage peaks are 

integrated.

The procedure
1.

Check if the supply voltage matches the specified supply voltage on the nameplate.

2.

Switch off the supply voltage before connecting the device. 

3.

Remove housing cover.

4.

Guide cable through the gland. Preferably use twisted, screened two-wire cable.

5.

Connect device in accordance with the following diagram.

6.

Screw down housing cover.

7.

Switch on supply voltage.
