1.2 Application in explosion hazard areas

Danger!

Danger of explosion!

Combustion hazard. Blast wave: Flying parts can cause death.

The relay module RM1, the mains unit NG1 and the connecting cables are not suitable for use in explosion

hazard areas!

If the relay module itself is not located in an explosion hazard area the relay module RM1 230 V may

supply the power and signals to the operating unit in zone 1.

For this application the relay module must be used with an ambient temperature of -20 up to +40°C. This

temperature range is also applied to the measured liquid when the relay module is mounted on the basic

flow meter.
