1.4 DC Power Injector
The DC Power Injector is an indoor unit designed for sites in which protected DC
sources are available (48 to 55 VDC), such as many of the GSM sites. This allows
operators to utilize their existing protected backup DC systems to feed the VL
outdoor units. For this purpose, the unit comes with a 3 m DC cable, with an
RJ45 plug at one end that goes into the injector and 3 wires (+, -, GND) at the
other end that will need to go into a plug suitable for the DC power source.
