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.
