Industrial Personal Computer Interface Connections
Introduction
The information below describes usage of the interface connections of the Industrial
Personal Computer in Class I, Division 2 Groups A, B, C, and D hazardous
locations.
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.
WARNING
EQUIPMENT DISCONNECTION OR UNINTENDED EQUIPMENT OPERATION
 Ensure that power, communication, and accessory connections do not place
excessive stress on the ports. Consider the vibration environment when making
this determination.
 Securely attach power, communication, and external accessory cables to the
panel or cabinet.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
