DANGER
POTENTIAL FOR EXPLOSION
 Always confirm the ANSI/ISA 12.12.01 and CSA C22.2 N
213 hazardous
location rating of your device before installing or using it in a hazardous location.
 To power on or power off a Industrial Personal Computer installed in a Class I,
Division 2 hazardous location, you must either:
 Use a switch located outside the hazardous environment, or
 Use a switch certified for Class I, Division 1 operation inside the hazardous
area.
 Do not connect or disconnect equipment unless power has been switched off or
the area is known to be non-hazardous. This applies to all connections including
power, ground, serial, parallel, network and rear USB connections.
 Never use unshielded / ungrounded cables in hazardous locations.
 When enclosed, keep enclosure doors and openings closed at all times to avoid
the accumulation of foreign matter inside the workstation.
 Use only non-incendive front USB configurations (see page 69).
Failure to follow these instructions will result in death or serious injury.

 If wiring of I/O lines near power lines or radio equipment is unavoidable, use
shielded cables and ground one end of the shield to the Industrial Personal
Computer ground connection screw.
 Do not wire I/O lines in proximity to power cables, radio devices, or other
equipment that may cause electromagnetic interference.
Failure to follow these instructions can result in death, serious injury, or
