Safety Summary (continued)
Operating Environment
Before the AC 800M Controller system is brought online, investigate which
environmental conditions are applicable. Take note in particular of the
following:
• The controller must not be exposed to conditions that exceed the values given
in the relevant technical specifications.
• The controller must not be used in an environment exposed to strong electrical
interference. Electrical machines can produce interference that exceeds levels
permitted for the equipment, for example during repair work.
• All products must be handled with appropriate precautions with regard to
electrostatic damage.
• The controller must not be exposed to direct sunlight.
Important Software Check
• Use the system’s fault-monitoring facilities to prevent accidents or mishaps.
• When in doubt, ALWAYS CHECK before executing changes.
Important Hardware Notice
• DO NOT, under any circumstances, disconnect the power supply to a
normally functioning system. Always use the correct system shut-down
procedure prior to disconnecting the power supply.
Signal Noise Due to Cables
Cables which may cause electrical interference (for example, power supply cables)
must not be installed adjacent to bus cables carrying fast digital signals. Ensure that
a minimum distance of 10 cm (4 in.) is provided between cables installed inside
cabinets.
Hazardous Electrical Supplies
Operational and maintenance procedures, during which personnel may come into
contact with high voltage, should only be carried out by personnel fully trained in
the maintenance of electrical equipment within those environments, and who are
fully aware of all risks involved.
