Regular Cleaning and Maintenance
Introduction
Inspect the Industrial Personal Computer periodically to determine its general
condition. For example:

Are all power cords and cables connected properly? Have any become loose?

Are all installation fasteners holding the unit securely?

Is the ambient temperature within the specified range?

Are there any scratches or traces of dirt on the installation gasket?
The following describes service/maintenance work which can be carried out by a
trained, qualified user.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH

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.

Unplug the power cable from both the Industrial Personal Computer and the


Always use a properly rated voltage sensing device to confirm power is off.

Replace and secure all covers or elements of the system before applying power
to the unit.

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


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 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, and network connections.

Never use unshielded / ungrounded cables in hazardous locations.

Use only non-incendive USB configuration.
