Chapter 1 - System Description DC Power Injector
BreezeACCESS 4900 10 System Manual
The DC Power Injector has two RJ45 jacks at one end (see Figure 1-4):
WAN/Eth: For connection to the network
DC IN: For connection to the DC power source via the supplied cable (see
Figure 1-5)
The other end has another RJ45 jack for connecting to the outdoor unit via an
Ethernet cable
CAUTION
When using the injector, the following restrictions apply:
The DC Power Injector does not include surge protection for either the DC or Ethernet input.
External protection devices are required for surge protection.
The nominal output voltage is between 50 to 58 VDC with a DC load of 0 to 1 A. If the nominal
output is below 50 VDC, the cable linking the IDU and ODU must be shorter than 100 m.
The external power supply must support overcurrent/short circuit protection with auto recovery
function. In case of overcurrent, the power supply must turn off and on (hiccup mechanism).
