Installing Your Controller 21
Safety Considerations Safety considerations are an important element of proper system installation.
Actively thinking about the safety of yourself and others, as well as the
condition of your equipment, is of primary importance. We recommend
reviewing the following safety considerations.
Hazardous Location Considerations
This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D or
non-hazardous locations only. The following WARNING statement applies to
use in hazardous locations.
ATTENTION
Electrostatic discharge can damage semiconductor devices
inside the controller. Do not touch the connector pins or
other sensitive areas.
ATTENTION
Vertical mounting of the controller is not supported due to
heat build-up considerations.
ATTENTION
Be careful of metal chips when drilling mounting holes for
your controller or other equipment within the enclosure or
panel. Drilled fragments that fall into the controller or I/O
modules could cause damage. Do not drill holes above a
mounted controller if the protective debris shields are
removed or the processor is installed.
