4 Safety Considerations
Danger: High Voltages
When the TRN-2013 is integrated into the meter, high voltages are present:
CAUTION: When the TRN-2013 is mounted in a a Meter, the term “GND” or “Ground” does
NOT refer to Earth ground. All signals will have a 120/240/480VAC power
superimposed onto those lines. All signals to/from the TRN-2013 need to be
isolated. No grounded instruments or computers should touch the TRN-2013
signals.
It is recommended to use the following isolation/drivers.
