•
The marked input voltage of -48 VDC for a DC-powered services gateway is the nominal voltage
associated with the battery circuit, and any higher voltages are only to be associated with float voltages
for the charging function.
•
Because the services gateway is a positive ground system, you must connect the positive lead to the
terminal labeled RETURN, the negative lead to the terminal labeled -48V, and the earth ground to the
chassis grounding points.
