Coil circuit "Ex e" (Terminal 85,86)
Ui
30 V (70 V peak)
Ii
130 mA
Note
Compact mounted versions
For intrinsically safe data for MAG 3100 Ex compact mounted with MAG 6000 I Ex d, refer to the

WARNING
With intrinsically safe circuits
If a non-conforming supply unit is used, the "fail-safe" type of protection will no longer be
effective and the approval certification will be invalid.
With intrinsically safe circuits, use only certified meters appropriate for the transmitter.

Special conditions for safe use
It is required that:
• Electrical connections are in accordance with national requirements.
• Appropriate cable connectors are used for the output circuits:
– Intrinsically safe: blue
– Non-intrinsically safe: black
• Minimum 4 mm

cable is to be used for potential equalization
• Cable glands for coil circuit must be Ex e approved (increased safety) and fit the application
by being approved for the cable used as regards size and temperature.
