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.

Disconnecting Main Power

!

ATTENTION: Explosion Hazard — Do not replace components
or disconnect equipment unless power has been switched off and
the area is known to be non-hazardous.

The main power disconnect switch should be located where operators and
maintenance personnel have quick and easy access to it. In addition to
disconnecting electrical power, all other sources of power (pneumatic and
hydraulic) should be de-energized before working on a machine or process
controlled by a controller.
