APPLYING POWER
Power is supplied to the QTERM-A12 terminal via the COM1 serial port connector or the
3-pin power terminal strip for input power, return and chassis ground. The QTERM-A12 may
also be equipped with an optional Power-over-Ethernet (PoE) interface. When powered by the
3-pin power terminal strip or the COM1 serial port, the QTERM-A12 has a 10- to 32-volt DC
input range and can be powered directly from a 12- or 24-volt DC power supply (the current
will vary depending on the input voltage; see table below).
3.1 Connecting to Earth Ground
NOTE ☞ The chassis ground connection of the QTERM-A12 is electrically connected to the exposed
conductive parts of the QTERM-A12 for safety purposes. The chassis ground connection
MUST be connected to an external protective earthing system.
The QTERM-A12 has a chassis ground terminal and a chassis ground connection on the 3-pin
power terminal strip on the back of the terminal. (See Figure 6 on page 24 and Figure 15 on
page 29 for the location of the chassis ground terminal and the 3-pin power terminal strip.) The
terminal should be connected to earth ground (protective earth). The chassis ground is not con-
nected to signal common of the terminal. Maintaining isolation between earth ground and
signal common is not required to operate the terminal; however, other equipment connected to
the terminal may require isolation between signal common and earth ground. To maintain iso-

lation between signal common and earth ground, care must be taken when connections are
made to the terminal. For example, a power supply with isolation between its signal common
and earth ground must be used. Also, plugging in a serial cable or a USB cable may connect
signal common and earth ground.
The serial cable shield or the USB shield may be connected to earth ground at the host. The
serial cable or the USB shield, in turn, may also be connected to signal common.
3.2 Primary Serial Port Connector for Power Input
Power can be supplied to the terminal through pin 9 and ground return through pin 5 of the
COM1 serial port connector.
3.3 Terminal Strip for Power Input
The 3-pin terminal strip is used to provide input voltage and ground to the terminal. The termi-
nal strip provides a chassis ground connection. The chassis ground pin is isolated from the sys-
tem ground of the terminal.
WARNING Although the terminal includes protection circuitry to prevent power supply contention,
power should not be connected to the 3-pin terminal strip or the RJ45 PoE interface while
power is applied to the DB9 connector.
WARNING Although the terminal includes protection circuitry to prevent power supply contention,
power should not be connected to the DB9 connector or the RJ45 PoE interface while power
is applied to the 3-pin terminal strip.
WARNING QTERM-A12 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 10
volts DC power and be limited to a maximum of 32 volts DC. Limiting may be inherent to
the supply or may be provided by supplementary overcurrent devices. If the QTERM-A12
does not respond or exhibits abnormal behavior on power up, disconnect power and contact
Beijer Electronics for technical support.

Applying Power Optional Power-over-Ethernet Interface
QTERM-A12 Terminal 7
3.4 Optional Power-over-Ethernet Interface
The QTERM-A12 may be equipped with an optional Power-over-Ethernet (PoE) interface.
This interface may be used to power the terminal by connecting a PoE equipped Power Sourc-
ing Equipment (PSE) to the RJ45 connector on the rear of the terminal.
The QTERM-A12 PoE interface is functional with both IEEE 802.3af-2003 and 802.3at-2009
standards. If the terminal is connected to an IEEE 802.3af-2003 compliant network connection
the terminal will operate as a Type 1 Class 4 PoE device in a low-power condition not exceed-
ing 13 Watts average power consumption. The terminal will automatically disable both USB
ports while operating as a Type 1 Powered Device (PD) to ensure that the total average power
consumption remains lower than 13 Watts.
If the QTERM-A12 is connected to an IEEE 802.3at-2009 compliant network connection all
included features will be operational. In this mode, the terminal will complete 2-event classifi-
cation as specified by IEEE 802.3at-2009 and operate as a Type 2 Class 4 PoE Powered Device
(PD).
The QTERM-A12 will also operate from a non-compliant (simple Power-over-Ethernet with
no classification) PSE source if the source can supply up to 600 mA and maintain between
37.0 and 57.0 volts measured at the RJ45 connector on the terminal.
The QTERM-A12 will accept either Mode A or Mode B power connections as specified by
IEEE 802.3at-2009. The following table provides pinout information for both of these modes.
The polarity may be reversed in either mode.
NOTE ☞ The chassis ground connection MUST be connected to an external protective earthing system.
See section 3.1, “Connecting to Earth Ground” for more information.
WARNING Although the terminal includes protection circuitry to prevent power supply contention,
power should not be connected to the 3-pin terminal strip or the DB9 connector while power
is applied to the RJ45 PoE interface.

INSTALLATION
A QTERM-A12 terminal uses a rugged chemical resistant polymer housing and mounting
components. When properly installed in a NEMA-4X rated panel, the QTERM-A12 meets all
NEMA-4X specifications including hose-down, icing and salt spray.
A QTERM-A12 terminal can be installed in either a landscape or portrait orientation. In addi-
tion, the terminal can be installed with or without a front bezel. The model with factory-
installed front bezel is referred to as the standard version and the model without a front bezel is
referred to as the modular version.
The standard version of the QTERM-A12 has a factory-installed front bezel. This bezel has
molded-in studs that are used in combination with a terminal ring to mount the terminal to the
panel.
The modular version of the QTERM-A12 does NOT have a factory-installed front bezel. The
modular version of the terminal is ideal for installations that require a custom front bezel or no
bezel at all. The modular version requires that the mounting studs be integral with the panel
that the terminal will be mounted in.
Take the following steps to install the terminal:
•Decide whether to mount the terminal in portrait or landscape orientation. “Portrait” means
that the longest dimension is vertical; “landscape” means that the longest dimension is hori-
zontal.
•Cut a hole in the panel or drywall. See section 5.1, “Cutting Out for Panel Mount” for spec-
ifications.
•Install the QTERM-A12 terminal in the panel. See section 5.2, “Installing the Terminal” for
instructions.
•Connect cables to the terminal. Verify that the thumb screws are tight or the locks snapped
into place for each cable used.
•Apply DC power to the QTERM-A12 terminal. See Chapter 3, “Applying Power” for infor-
mation.
