Meridian 1 equipment is sensitive to static electricity and environmental
conditions. Follow the precautions in this chapter to avoid personal injury or
equipment damage.
Module covers are not hinged; do not let go of the covers. Lift covers
away from the module and set them out of your work area.
To avoid the danger of electric shock, be very careful when you work
with power equipment and connections. Warning notices are displayed
and must be heeded.
There are no user repairable components or assemblies in the power
system. If a power unit fails, the complete unit must be replaced. Do
not disassemble a power unit under any circumstances because of the
risk of electric shock.
Circuit cards may contain a lithium battery. There is a danger of
explosion if the battery is incorrectly replaced. Do not replace
components on any circuit card; you must replace the entire card.
Dispose of circuit cards according to the manufacturer's instructions.
To avoid damage to circuit cards from static discharge, wear a
properly connected antistatic wrist strap when you work on Meridian 1
equipment.
