Installing the UC-7122/7124
Wall or Cabinet Mounting
The UC-7122/7124 have built-in “ears” for attaching the embedded computers to a wall
or the inside of a cabinet. We suggest using two screws per ear to attach the
UC-7122/7124 to a wall or cabinet. The heads of the screws should be less than 6.0 mm
in diameter, and the shafts should be less than 3.5 mm in diameter, as shown by the
figure at the right.
DIN-Rail Mounting
DIN-rail attachments can be purchased separately to attach the product to a DIN-rail.
Wiring Requirements
This section describes how to connect serial devices to the embedded computer.
You should heed the following common safety precautions before proceeding with the installation of any
electronic device:
• Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must
cross, make sure the wires are perpendicular at the intersection point.
NOTE: Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.
• Use the type of signal transmitted through a wire to determine which wires should be kept separate. The
rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.
• Keep input wiring and output wiring separate.
• It is advisable to label the wiring to all devices in the system.
