3 Hardware Installation
3.1 Mounting and Installation Guidelines
The RXi Display is mounted directly onto a panel or enclosure. (Refer to the section
Mounting and Installation .) Adhere to the following guidelines for mounting and
installation:
• The RXi Display should be mounted on a flat surface in a UL/NEMA Type 1
enclosure.
• The RXi Display must be mounted with its cooling fins vertical to ensure adequate
air flow. Mounting orientation is permitted only with connectors oriented down.
• The panel should be capable of supporting the weight of the RXi Display without
distortion to the panel.
• Adequate air flow around the exterior of the unit is essential to maintain safe interior
temperature of the unit. Inlets and outlets must not be obstructed. (Refer to the table
Display Specifications .)
• You may need to allow more space for installation of cables and connectors than
what is required for heat dissipation. To avoid impacting mechanical reliability and
signal quality, cable installation must comply with the minimum bend radius
specified by the cable manufacturer.
3.2 Grounding
The following guidelines apply for proper grounding:
Note
These grounding connections serve as a path for reducing noise interference and
radiated emissions and are required for the RXi Display to comply with the standards
identified in
Appendix A .
• The RXi Display chassis requires a safety ground connection to protective earth. This
ground wire shall be at least 16 AWG (1.31 mm
2 cross section) and should be as
short as possible. When mounting the RXi Display, add the ground wire underneath
either of the two center screws attaching the RTM assembly to the display panel, and
connect to protective earth.
• The frame ground connection on the power plug should be a 16 AWG (1.31 mm 2
cross section) wire with shortest possible length. It is recommended that both ground
wires terminate in a star wiring pattern at the same grounding point, and connect to
protective earth.
