When connecting the radio to a MAINS DC distribution system, use a 2A circuit
breaker to enable the central DC system to isolate the radio in an emergency
case.
Use one poly circuit breaker and should connect it on the live voltage: (+) or ( -).
The other poly should be grounded.
Connect the circuit breaker to the (+) or (-) live voltage.
The DC input is floating, so either (+) or (-) can be connected to the GND on the
power supply side. For the sake of consistency with other systems, we
recommend that you connect the (+) to the GND.
Use a two-wire cable (14-18 AWG) to connect the power supply to the radio. On
the radio DC terminal, connect the (+) and (-) wires to the correct ports.
Caution:
Use DC power supply which is safety approved to UL/EN/IEC 60950-1 with rated
voltage of 42-57 VDC and rated current of 2A max

2.8.1.2
PoE Power
Connect Power over Ethernet (PoE) to port Eth1 only.
The PoE power range of the unit is 42-57V.
The power source should be limited to 1.4A to avoid surges and possible damage
to the radio.
Caution:
Use a PoE power supply which is safety approved to UL/EN/IEC 60950-1 as a limited
power source (LPS) with rated voltage of 42-57 VDC and rated current of 1.4A max
