●
When a procedure requires that you power off the system:
–
Lock the wall box-switch in the off position.
–
Attach a DO NOT OPERATE tag to the wall box-switch.
●
Never assume that the power is turned off. Always check to ensure that a circuit does not
have power.
●
Do not work alone. Work with another person who knows the locations of the power-off
switches, especially if you are working with
exposed electrical circuits.
●
Follow the instructions in the manual carefully, especially when working with circuits that
are powered. Disconnect power when instructed to do so in the procedures.
●
Disconnect all power before working near power supplies unless otherwise instructed by a
maintenance procedure.
●
Disconnect all power before installing changes in machine circuits unless otherwise in-
structed by a maintenance procedure.
●
High voltages capable of causing shock are used in this equipment. Be extremely careful
when measuring high voltages and when servicing cards, panels, and boards while the
system is powered on.
●
Do not wear jewelry or other metal objects.
●
When possible, work with one hand so that a circuit is not created. Keep the other hand in
your pocket or behind your back.
●
Use caution when installing or modifying telephone lines. Never install telephone wiring
during an electrical storm.
●
Never install a telephone jack where it can get wet unless the jack is specifically designed
for wet conditions.
●
Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface.
●
Avoid using a telephone (other than the cordless type) during an electrical storm due to the
remote risk of shock from lightning.

●
Look for hazards in your area and eliminate them. Examples are moist floors, ungrounded
power extension cables, power surges, and missing safety grounds.
●
Rubber electrostatic mats will not protect you from electrical shock. Do not use them for
this purpose. Stand on suitable rubber mats to insulate you from grounds such as metal
floor strips and machine frames.
