5.2 Cable connection
5.2.1 Standard design, HART
1. A suitable voltage supply cable must be used for the electrical connection of the transmitter.
2. Unscrew the cover from the cable connection area at the rear of the transmitter.
Important
After switching off the supply power, wait t > 2 minutes before opening the flameproof
housing. (Hazardous area protection only!)
3.
Insert the supply voltage cable into the cable connection area through the cable gland and
fasten to the cable grip to prevent accidental disconnection.
4. Tighten the cable gland.
Notice - Potential damage to parts!
If the supply voltage cable is not fastened with the cable grip, there is a risk of it being pulled
completely out of the transmitter housing should the strain fall below the required level,
thereby interrupting the electrical connection.
The sheathing of the supply voltage cable must not be damaged. Otherwise, protection class
IP 67 for the flowmeter cannot be ensured.
5.
Remove the insulation from the cable sheath and the wires and connect these to the
corresponding terminals (see the section titled "Cable connection area").
6. Screw on the cover for the cable connection area fully and fasten hand-tight. Make sure the
gaskets for the cover are seated properly.
5.2.2 Connection via flameproof cable gland (“Ex d design“)
The electrical connection for the flowmeter is made via the cable gland on the unit. Alternatively,
the flowmeter can be connected using an approved flame-resistant conduit gland located
directly on the unit. If this option is selected, the cable gland has to be removed first.
Important
The requirements set out in EN 500181 Section 13.1 and 13.2 must be complied with.
The requirements to be met by integrators set out in EN 60079-14 must be complied with
when selecting conduit glands.
