2.8.2 DC Power Supply Notes
The DC power input range of the ODU is 36 - 57 VDC.

The DC supply should be limited to two ampere to avoid surges and possible
damage to the ODU. For that, use limited power supply or circuit breaker
(fast-blow fuse). The circuit-breaker is the disconnecting device, and should
be readily accessible.

When connecting the ODU to a MAINS DC distribution system, use a two
ampere circuit breaker to enable the central DC system to isolate the ODU 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, Siklu
recommends that you connect the (+) to the GND.

Use a two-wire cable (14-18 AWG) to connect the power supply to the ODU.
On the ODU DC terminal, connect only the (+) and (-) wires. Do not connect
to the ODU's GND input.
Caution:
Disconnect all power cables before service!
