TP 560/E - Electrical Safety
Applicable to: World-Wide
Electrical Safety:
Observe the following rules when working on electrical equipment.
Important: |
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
Before you start to work on the machine, unplug the power cord. If you cannot unplug it, ask the customer to power-off the wall box that supplies power to the machine and to lock the wall box in the off position.
If you need to work on a machine that has exposed electrical circuits, observe the following precautions:
- Ensure that another person, familiar with the power-off controls, is near you.

Attention: |
Regularly inspect and maintain your electrical hand tools for safe operational condition.
Do not use worn or broken tools and testers.
Never assumethat power has been disconnected from a circuit. First, checkthat it has been powered-off.
Always look carefully for possible hazards in your work area. Examples of these hazards are moist floors, nongrounded power extension cables, power surges, and missing safety grounds.
Do not touch live electrical circuits with the reflective surface of a plastic dental mirror. The surface is conductive; such touching can cause personal injury and machine damage.
Do not service the following parts with the power onwhen they are removed from their normal operating places in a machine:
- Power supply units
- Pumps
- Blowers and fans
- Motor generators
and similar units. (This practice ensures correct grounding of the units.)
If an electrical accident occurs:
- Use caution; do not become a victim yourself.
- Switch off power.
- Send another person to get medical aid.
