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
Vertical mounting of the controller is not
recommended 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.
