Hardware Connection Description

In this chapter, we describe how to connect the UC-5100 to a network and various devices for first time testing purposes.

Wiring Requirements

In this section, we describe how to connect various devices to the embedded computer. Be sure to read and follow these 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 strongly advised that you label wiring to all devices for easy identification.

ATTENTION

Safety First!
Be sure to disconnect the power cord before installing and/or wiring your UC-5100 Series computers.

Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes dictating the maximum current allowable for each wire size. If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment. This equipment is intended to be supplied by a certified External Power Supply, the output of which meets SELV and LPS regulations.

• The wiring for the input terminal block must be installed by qualified and experienced professionals.
  • Wire Type: Cu, FW2.
  • Use 28-14 AWG wire size and a torque value of 0.2 N-m.
• Use only one conductor in a clamping point between the DC power source and the power input.

Temperature Caution!
Be careful when handling the unit. When the unit is plugged in, the internal components generate heat, and consequently the outer casing may feel hot to the touch.
This equipment is intended for installation in Restricted Access Locations.

Connecting the Power

SG: The Shielded Ground (sometimes called Protected Ground) contact is at the bottom contact of the 3-pin power terminal block connector when viewed from the angle shown here. Connect the wire to an appropriate grounded metal surface or through the grounding screw on top of the device.

NOTE
The input rating of UC-5100 Series is 9 to 48 VDC, 0.95 to 0.23 A.

ATTENTION
The product is intended to be supplied by a UL Listed Power Supply suitable for use at Tma = 85°C whose output meets ES1 and PS2/LPS rated 9 to 48 VDC, 0.95 A (min.), or 48 VDC, 0.23 A (min).

Altitude Requirement
This product and the listed power supply (LPS) adapter(s) used with it are UL- certified for operation at 2,000 meters. Although the product is tested at 5,000 meters, it is not UL-certified for this altitude. For reliable performance of the product in high-altitude installations of over 2,000 meters (e.g., 5,000 meters), use a suitable adapter that is tested and certified at the altitude (i.e.,5,000 meters).

Grounding the Unit
Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw to the grounding surface prior to connecting devices.

ATTENTION
This product is intended to be mounted to a well-grounded mounting surface such as a metal panel. Use the green-and-yellow cable type minimum with American Wire Gauge (AWG) 14 (2.5 mm2) for grounding.

ATTENTION
A shielded power cord is required to meet FCC emission limits and also to prevent interference with nearby radio and television reception. It is essential that only the supplied power cord be used.
You are cautioned that changes or modifications not expressly approved by the party responsible for compliance could void your authority to operate the equipment.
