•
Use only approved tools and test equipment. Some hand tools have handles covered with a
soft material that does not insulate you when you are working with live electrical currents.
•
Do not use rubber floor mats that contain small conductive fibers to decrease electrostatic
discharge as protection from electrical shock.
•
Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical
outlet. If an electrical accident occurs, you can then operate the switch or unplug the
power cord quickly.
•
Do not work alone under hazardous conditions or near equipment that has hazardous
voltages.
•
Disconnect all power before:
•
Performing a mechanical inspection.
•
Working near power supplies.
•
Removing or installing main units.
•
Unplug the power cord before you start to work on the equipment. If you cannot unplug
it, ask the customer to power off the wall box that supplies power to the equipment and
lock the wall box in the Off position.
•
If you need to work on equipment that has exposed electrical circuits, observe the
following precautions:
•
Make sure another person is near you that is familiar with the power-off controls.
Remember:
Another person must be there to switch off the power, if necessary.
•
Use only one hand when working with powered-on electrical equipment. Keep the
other hand in your pocket or behind your back.
Remember:
There must be a complete circuit to cause electrical shock. By observing
the above rule, you may prevent current from passing through your body.
•
When using testers, set the controls correctly and use the approved probe leads and
accessories for that tester.
•
Stand on suitable rubber mats (obtained locally, if necessary) to insulate you from
grounds such as metal floor strips and equipment frames.
•
Observe special safety precautions when you work with very high voltages. These
instructions are in the safety sections of maintenance information. Use extreme care
when measuring high voltages.
•
Regularly inspect and maintain your electrical hand tools for safe operational condition.
•
Do not use worn or broken tools and testers.
•
Never assume that power has been disconnected from a circuit. First, check that it has
been powered off.
