CHAPTER 4 SYSTEM SAFETY
4-1 Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm and the Acnodes
RMC7189 from damage:
o Be aware of the locations of the power on/off switch on the chassis as well as the room's emergency
power-off switch, disconnection switch or electrical outlet. If an electrical accident occurs, you can then
quickly remove power from the system.
o Do not work alone when working with high voltage components.
o Power should always be disconnected from the system when removing or in- stalling main system
components, such as the motherboard, memory modules and floppy drive. When disconnecting power,
you should first power down the system with the operating system first and then unplug the power
cords of all the power supply units in the system.
o When working around exposed electrical circuits, another person who is familiar with the power-off
controls should be nearby to switch off the power if necessary.
o Use only one hand when working with powered-on electrical equipment. This is to avoid making a
complete circuit, which will cause electrical shock. Use extreme caution when using metal tools, which
can easily damage any electrical components or circuit boards they come into contact with.
o Do not use mats designed to decrease static electrical discharge as protection from electrical
shock. Instead, use rubber mats that have been specifically designed as electrical insulators.
o The power supply power cords must include a grounding plug and must be plugged into grounded
electrical outlets.
