IMPORTANT
Observe the following precautions:
 It is important to follow the installation procedures described in this chapter very
carefully. Power wiring and grounding from the building to the S300 expansion
enclosures must only be performed by certified electricians. Failure to have
qualified professionals perform these functions can result in personal injury,
damage to a facility’s electrical system and other equipment, or damage to the
system and devices.
 Electronic components such as the printed circuit board assemblies used in the
S300 expansion enclosures are extremely static sensitive. To prevent
electrostatic discharge (ESD) damage, a properly grounded wrist strap must be
used at all times when handling the components. If a wrist strap is not available,
touch any part of the metal CK721-A cabinet prior to handling components to
discharge static electricity. It is advisable to avoid working on carpeted areas if
possible.
