2.1 Installation Planning

2.1.1 Safety Considerations

Before installing the module, you must identify the personnel hazards that may be created in
the event of a system failure and provide interlocks and safety switches to prevent operation
during a system failure. Refer to the NEMA ICS 3-304 Programmable Control Standards.
As a system designer, you should be aware that Control devices can fail in an unsafe condition. Unless
you incorporate proper safeguards, malfunction of the controller or associated devices, such as
operator interface equipment, could cause sudden equipment startup, shutdown, or other unexpected
operation. Such startup or shutdown or unexpected operation could result in death or serious injury to
If you or your company are using CTI controllers with equipment that requires the presence of a person
(such as an operator or attendant), you should be aware of this potential safety hazard and take
The precautions below conform to the National Electrical Manufacturers Association
guidelines for installation of programmable controllers as recommended in the NEMA ICS 3–
304 Programmable Control Standards.
ICS 3-304.81 Safety Recommendations:
Consideration should be given to the use of an emergency stop function which is
independent of the programmable controller. Where the operator is exposed to the
machinery, such as in loading or unloading a machine tool, or where the machine cycles
automatically, consideration should be given to the use of an electromechanical override or
other redundant means, independent of the programmable controller, for starting and
interrupting the cycle. If provision is required for changing programs while the equipment is
in operation, consideration should be given to the use of locks or other means of assuring
that such changes can be made only by authorized personnel. These recommendations are
