Warning
As a safety precaution, install a circuit breaker with a minimum value of 50 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. E9
Warning
For centralized DC power connection, install only in a restricted access area. E23
