4.1.1 Power supply
The dc power supply should provide power with less than two percent ripple.
The transmitter requires between 9 and 32 Vdc at the terminals to operate
and provide complete functionality.
4.1.2 Power conditioner
The DP/PA coupler/link often includes an integrated power conditioner.
4.1.3 Grounding
Transmitters are electrically isolated to 500 Vac rms. Signal wiring can not be
grounded.
4.1.4 Shield wire ground
Shield wire usually requires a single grounding point to avoid creating a
ground loop. The ground point is typically at the power supply.
