ELECTRICAL INSTALLATION
3.3.1.
INTRODUCTION
•
Make sure, the installation is made safe and the activities are approved by the
responsible person. Lock-out/Tag-out the related systems as applicable before you
start the work.
•
Electro static discharge may inflict irreparable damage to electronics! Before
installing or opening the unit, the installer must be discharged by touching a well-
grounded object.
•
This unit must be installed in accordance with the related certificates, the plant
owner’s and the manufacturer’s instructions and the prevailing (inter)national
Standards and Regulations.
•
Both internal power supply as well as the relays are double insulated.
•
To improve ESD sensitivity it is recommended to ground the conductive front panel at
one of the chassis ground points.
•
Grounding: Do ground the aluminum enclosure part properly as indicated. Two
grounding positions are available: one on the top side (photo) and one on the bottom

VOLTAGE SELECTION SENSOR SUPPLY
Sensor supply: 8.2V - 12V or 24 V DC:
A real power supply for the sensor is available.
The flowmeter can be powered with 8.2, 12 or
24V DC. Total power consumption: max.
50mA@24V. The voltage is selected with the
two switches at the left rear of the enclosure.
Refer to the figure 15 to select the required
sensor supply voltage.
