2.2 Electrical safety
Observe the rules that follow when working on electrical equipment.
◼ Use only approved tools and test equipment (GS-, IEC 60900-, VDE standards). Some hand tools
have handles covered with a soft material that does not insulate you when working with live electrical
currents.
◼ Many customers have, near their equipment, rubber floor mats that contain small conductive fibres
to decrease electrostatic discharges. Do not use this type of mat to protect yourself from electrical
shock.
◼ Locate the (room/place) 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 equipment, 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.
◼ Observe the precautions that follow if you need to work on equipment that has exposed electrical
circuits:
 Ensure that another person, familiar with the power-off controls, is near you. That person must
be present 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.
CAUTION:
An electrical shock can only occur when there is a complete circuit. By observing the above
rule, you may prevent a 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 machine frames.
◼ 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. Always check that it has been
powered off.
