Before the PM851 SBSE018168R1 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.
