6.2 Electrical mounting

■

The instrument must be earthed via the process connection.

■

For instruments with voltage output, use shielded cable, and, if the cables are longer than 30 m or

they leave the building, earth the shield at least at one end of the cable.

■

In North America, use the instrument in line with "class 2 circuits" or "class 2 power units" in accord-

ance with CEC (Canadian Electrical Code) or NEC (National Electrical Code).

■

Select a cable diameter that matches the cable gland of the plug. Make sure that the cable gland of

the mounted plug has a tight t and that the seals are present and undamaged. Tighten the threaded

connection and check that the seal is correctly seated, in order to ensure a tight seal.

■

For cable outlets, make sure that no moisture enters at the cable end.
