2.4.3 Applying Power
Power is supplied to the QTERM-G75 terminal via the primary serial port connector. Refer to
section 2.2.1, “Serial Ports” for the pin assignments for power and ground. DC power must be
in the range of 8 to 26 volts (the current will vary depending on the input voltage; see table
below).

CAUTION
QTERM-G75 power must come from an SELV (Safety Extra Low Voltage) power source
and should have a current limit on its output of 5 Amperes. It must provide a minimum of 8
volts DC power and be limited to a maximum of 26 volts DC. Limiting may be inherent to
the supply or may be provided by supplementary overcurrent devices. If the QTERM-G75
does not respond or exhibits abnormal behavior on power up, disconnect power and contact
Beijer Electronics for technical support.
