Product Related Information
Industrial Personal Computers are certified for use in Class I, Division 2 hazardous
locations as defined in ANSI/ISA 12.12.01 or CSA C22.2 N
°213. Observe the
following:
(1) For additional information, refer to NEMA ICS 1.1 (latest edition), "Safety
Guidelines for the Application, Installation, and Maintenance of Solid State Control"
and to NEMA ICS 7.1 (latest edition),"Safety Standards for Construction and Guide
for Selection, Installation and Operation of Adjustable-Speed Drive Systems" or
other applicable standards in your location.
NOTE: Industrial Personal Computer is a highly configurable device and is not
based on a real-time operating system. Changes to the software and settings of the
following must be considered new implementations as discussed in the previous
warning messages. Examples of such changes include:
z System BIOS
z System Monitor
z Operating system
z Installed hardware
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
z Remove all power from the device before removing any covers or elements of
the system, and prior to installing or removing any accessories, hardware, or
cables.
z Unplug the power cable from both the Industrial Personal Computer and the
power supply.
z Always use a properly rated voltage sensing device to confirm power is off.
z Replace and secure all covers or elements of the system before applying power
to the unit.
z Use only the specified voltage when operating the Industrial Personal
Computer. The AC unit is designed to use 100...240 Vac input. The DC unit is
designed to use 24 Vdc. Always check whether your device is AC or DC
powered before applying power.
Failure to follow these instructions will result in death or serious injury.
WARNING
LOSS OF CONTROL
z The designer of any control scheme must consider the potential failure modes
of control paths and, for certain critical control functions, provide a means to
achieve a safe state during and after a path failure. Examples of critical control
functions are emergency stop and overtravel stop.
z Separate or redundant control paths must be provided for critical control
functions.
z System control paths may include communication links. Consideration must be
given to the implications of unanticipated transmission delays or failures of the
link.(1)
z Each implementation of a Industrial Personal Computer must be individually
and thoroughly tested for proper operation before being placed into service.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
