Fuse Chassis Ground
CDM-600L DC Modem Installation: The DC input CDM-600L is connected to a nominal 48
VDC prime power source. The DC input is isolated from the chassis and from the DC output to
the BUC if equipped with internal BUC power supply. The chassis may be connected to a local
system ground using a separate wire to the ground stud on the back of the chassis. Since the DC
input is isolated, either the positive or the negative side of the DC input may be common with
local ground. Labeling on the back of the chassis indicates the positive and negative terminals of
the input power socket.
The modem is supplied with a 2-wire power cable (CEFD part number CA/WR10327-1) with one
end terminated with a connector that mates with the modem input power socket. Positive DC
input is on the red wire, while negative DC input is on the black wire. The DC input connector is
Molex PN 03-12-1026 with Molex PN 08-12-1222 pins.
