Electrical Safety
Only qualified and properly trained personnel should perform electrical/electronic
troubleshooting and repair. Consider the following electrical system safety guidelines:
•
Before you troubleshoot or service a fastening system station, be sure you have an up-to-
date and appropriate set of electrical drawings for that station.
•
Remove metal items, such as rings, metal necklaces, wristwatches and jewelry, as these
can create electrical hazards. Wear medical alert identification cautiously.
•
Wear safety glasses, but avoid wearing those that have metal rims or metal side shields.
•
It may be necessary to troubleshoot equipment while the power is ON. ONLY qualified,
trained personnel should do this. During these instances, open only the panels, doors, or
covers which need to be opened. Know the voltage present at all points before you begin
troubleshooting.
•
Use properly insulated tools when working on electrical equipment to reduce the
possibility of shock. Make sure the insulation is adequate to safeguard against the high
voltages present.
•
If you must work on the electrical system, be sure the main disconnect switch on the
power panel is in the OFF position and locked out with locks from each trade involved
in the repair.
•
Do not attempt to modify or repair the machine without the approval of the proper
authorities.
•
Use approved fuse pullers when changing fuses.
•
Never use jumper wires or fuse substitutes to replace specified fuses.
•
Always use fuses of a capacity smaller than or equal to the safe capacity of the line or
the equipment it serves.
•
Before you work on any circuit, check it with an appropriate testing device to be sure
voltage is not present.
•
Install temporary wiring as safely as possible and replace it with permanent wiring as
soon as possible. Install grounding wherever it is needed in the final installation. If
modifications are made to the system wiring, drawings must be revised to illustrate this
change.
•
Know how to deal with electrical fires properly. Keep carbon dioxide and powder
extinguishers handy.
