Safety Precautions
•Always hold an insulated part of the P&E cable. Never touch the RJ45 connector.
•Do not touch the pins inside the P&E port on the PI with your hands or a conductor.
•Be sure to connect the power cables of the PI correctly to the positive and negative terminals of the power supply
device .To prevent damage to power cables or devices caused by short-circuits, install a circuit breaker on the
negative terminal of the power supply device.
•Do not install or remove a live P&E cable.

Principles and Application Scenarios
ProductOverview
The RTN PI-DC A11 receives one channel of DC power signals and one channel of GE service signals.
The signal coupling module couples DC power signals and GE service signals into P&E signals and outputs the P&E signals
to the P&E port.
The frequencies of DC power signals and GE service signals do not interfere with each other. Therefore, the two types of
signals can be transmitted over the same twisted pair.
