FPC-8057 User’s Manual
2.2.3 CE Requirements
To make a FPC-8057 comply with EMC directives, and to reduce
susceptibility to electrical interference, a separate #14 AWG ground wire
should be taken to the chassis ground terminal of the power connector. This
ground connection should be run directly to the central star earth
connection point (as recommended in most Installation Instructions).
2.2.4 Safety Guidelines
This section presents recommended installation practices, and
procedures. Since no two applications are identical, these
recommendations should be considered as guidelines.
Hardware Considerations WARNING!
The system designer should be aware that devices in Controller systems
could fail and thereby create an unsafe condition. Furthermore, electrical
interference in an operator interface, such as a FPC-8057 can lead to
equipment start-up, which could result in property damage and/or physical
injury to the equipment operator.
If you, or your company, use any programmable control systems that
require an operator or attendant, you should be aware that this potential
safety hazard exists and take appropriate precautions. Although the specific
design steps depend on your particular application, the following
precautions generally apply to installation of solid-state programmable
control devices. In addition, these precautions conform to the guidelines for
installation of Controllers as recommended in the NEMA ICS 3-304 Control
Standards.
