CHAPTER 5
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 addition, the terminal can be installed with or without a front bezel. The model with factoryinstalled 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 term inal 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 horizontal.
• 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 T erminal” 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.

Take the following steps to install the terminal.
1. Verify that the panel surface around the cutout is clean and free of rough edges. A gasket
built into the terminal seals against the panel surface. Dirt or imperfections on the panel
may prevent a proper seal.
2. Place the terminal over the panel cutout by aligning the terminal mounting holes with the
mounting studs of the panel. Ensure that the orientation is correct. The printed labels on

the back panel may indicate the orientation. If not, you can determine which side should
be at the top by the position of the serial port(s) on the back panel as follows:
• Landscape
When looking at the front of the unit, the back panel serial port(s) should be facing down.
• Portrait
When looking at the front of the unit, the back panel serial port(s) should be facing left. Refer to
Figure 4 for an example of a landscape installation.

3. Install nuts and washers ont o each of the six mo unting studs. Torque all nuts to 67.8 N cm
(6 lbs in) to create a seal between the terminal gasket and the panel. Avoid overtightening
the nuts.

WARNING
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 primary DB9 connectors.
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 pro vide 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
