Cable Connections - Xycom KPM Series User Manual

Chapter 2 – Installation
KPM(T) Series Flat Panel Industrial Monitor
Division 2 Hazardous Locations' regulations require that all cable connections be
provided with adequate strain relief and positive interlock. Front panel
keyboard/mouse and USB ports may be used in Hazardous Locations with
appropriate ratings if their electrical load characteristics comply with the Control
Drawing on 29.
All communication cables should include a chassis ground shield. This shield should
include both copper braid and aluminum foil. The D-sub style connector housing
should be a metal conductive type (e.g., molded zinc) and the ground shield braid
should be well terminated directly to the connector housing. Do not use a shield drain
wire.
The outer diameter of the cable must be suited to the inner diameter of the cable
connector strain relief in order to ensure that a reliable degree of strain relief is
maintained.
Warning
Never connect or disconnect the communication cables while power is applied at either
end of the cable. This may result in an incendiary spark and permanent damage to the
workstation communication components may occur.
Note
This warning does not apply to the front panel keyboard and USB interface connectors.
These connections are nonincendive circuits. Please refer to the Hazardous Locations
control drawing on page 29.
