Power Switch
The amount of input power required by systems with a Industrial Personal Computer
classifies the power switch as an incendive device because the voltage and current
across the make/break component are capable of generating a spark.
If using an ordinary power switch, hazardous location regulations require the power
switch be located in an area specified as non-hazardous.
However, limits in cable length between the workstation and the power switch may
apply. Otherwise the switch must be compliant with Class I, Division 1 requirements
(intrinsically safe). These switches are built in a manner that prevents the possibility
of a spark when contact is made or broken.
Use suitable UL listed and/or CSA Certified Class I, Division 1 switches in hazardous
locations. These switches are available from a wide number of sources. It is the
responsibility to ensure you select a power switch that conforms to the hazardous
location rating for the installation.

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

powered before applying power.
Failure to follow these instructions will result in death or serious injury.
