Grounding meter electronics housing

Daniel 3812 Liquid Ultrasonic Flow Meter electronics should be internally grounded for
intrinsically safe operations. Connect a wire to the chassis ground lug installed inside the
Transmitter Electronics Enclosure as the primary ground. A secondary ground is located outside
of the Transmitter Electronics Enclosure
connected to chassis ground.
The internal grounding terminal shall be used as the primary equipment ground. The
external terminal is only a supplemental bonding connection where local authorities permit
or require such a connection.
