iii RS-232C/RS-422 Serial Interface OptionSafety PrecautionsSafety PrecautionsCAUTION: Handling ESD-Sensitive PartsMany electronic parts use parts that are known to be sensitive to electrostatic discharge (ESD). Toprevent damage to ESD-sensitive parts, follow the instructions below in addition to all the usualprecautions, such as turning off power before removing logic boards:• Keep the ESD-sensitive part in its original shipping container (a special “ESD bag”) until you areready to install the part into the machine.• Make the least-possible movements with your body to prevent an increase of static electricity fromclothing fibers, carpets, and furniture.• Use an ESD wrist strap on your wrist if available. Connect the wrist band to the system groundpoint. This discharges any static electricity in your body to the machine.• Hold the ESD-sensitive part by its edge connector cover; do not touch its pins. If you are removinga pluggable module, use the correct tool.• Do not place the ESD-sensitive part on any metal surface; if you need to put down the ESD-sensi-tive part for any reason, first put it into its special bag.• Metal surfaces are electrical grounds. They increase the risk of damage because they make a dis-charge path from your body through the ESD-sensitive part. (Large metal objects can be dischargedpaths without being grounded.)• Prevent ESD-sensitive parts from being accidentally touched by other personnel.• Take extra care working with ESD-sensitive parts when cold weather heating is used because lowhumidity increases static electricity.WARNING: To prevent the danger of electric shock, before installing any options be sure toturn the power switch of the printer to the off [O] position and disconnect the power cord fromthe wall outlet.
