Warning: As a safety precaution, install a circuit breaker with a
minimum value of 15 Amps between the equipment and the DC
power source.
Always connect the wires to the LAN equipment first before you
connect the wires to the circuit breaker. Do not work with HOT
feeds to avoid the danger of physical injury from electrical shock.
Always be sure that the circuit breaker is in the OFF position
before connecting the wires to the breaker.
