Planning for installation
Contents of this chapter
This chapter gives instructions and references to instructions in other manuals for planning
the safety system installation, as well as the requirements for installation in the applicable
safety standards.
Requirements for designers and installers
• Designers and installers must be trained to understand the requirements and principles
of designing and installing safety-related systems.
• Designers and maintainers must be trained to understand the causes and consequences
of Common Cause Failures (CCF). See the checklist for the appropriate standard in
section
Common cause failure (CCF) checklists (page 41) .
Installation site
The subsystem elements must always be likely to operate within the range of temperature,
humidity, corrosion, dust, vibration, etc. for which they are specified, without the use of
external environmental control (see section
Technical data ).
The FSPS-21 module must only be used in an environment where no conductive dust or
contaminants are present. One way to ensure proper protection against contamination is
to use the FSPS-21 module in at least an IP54 enclosure. For further information on
environmental limits, see chapter
Planning the mechanical installation in the drive hardware
manual.
WARNING!
If you operate the drive system with a safety module in environmental conditions
that are outside of the specified ranges for the safety module, this can cause that
a safety function is lost.
