Hazardous Area requirements
• Hazardous Area Installation.
• For further information please see supplementary installation and operating instructions.
• Please follow these guidelines explicitly for mechanical and electrical connections.
• General cabling guidelines.
To maintain the IP 67 / NEMA 4x protection it is necessary to ensure that the correct size cable is used for
the cable glands. Please ensure that the cable glands are well tightened. Provide a “drop” loop for water
to drip off.
2.5 Inputs and outputs

The MFC 050 has many options and variations for the inputs/outputs.
The meter is shipped from the factory with one of the following options pre-configured:
Option Function
1
1 x current,1 x pulse,1 control input,1 x status output-HART
2 1 x current plus Modbus
3 Dual phase frequency output, 1 x current, 1 x control input - HART
4 2 x current, 1 x pulse, 1 x control input, HART
5 2 x current, 1 control input,1 x status output-HART
6 3 x current, 1 x pulse - HART
7 3 x current, 1 x control input - HART
8 3 x current, 1 x status output - HART
If you are not sure what option is fitted to the converter, this may be viewed at program Fct. 4.1 IO
FITTED.
On the MFC050, the inputs/outputs have a common signal ground that is galvanically isolated from the
Potential Earth (PE).
