7.4.3 Applying Power
Power is supplied to the QTERM-G72 terminal via the primary serial port connector or the
3-pin power terminal strip for input power, return, and chassis ground. Refer to section 7.2.1,
“Primary Serial Port (Multiprotocol Port Interface)” for the pin assignments for power and
ground. DC power must be in the range of 10 to 32 volts (the current will vary depending on
the input voltage; see table below).
Make sure to connect the chassis ground connection first.

CAUTION
Although the terminal includes protection circuitry to prevent power supply contention,
power should not be simultaneously connected to both the 3-pin terminal strip and the pri-
mary DB9 connectors.
