Safety is the responsibility of the user. Always operate the equipment in
accordance with the instructions, always paying full attention to local safety
practices and procedures.
This equipment must be operated only by trained and competent personnel who
are aware of the dangers and hazards involved in high-voltage-testing and other
HV-apparatus. HAEFELY accepts no liability for loss, damage, injury or death
caused by the incorrect or unsafe operation of this equipment.
General Safety is the most important aspect when working on or around high voltage electrical
equipment. Personnel whose working responsibilities involve testing and maintenance of the
various types of high voltage equipment must have understood the safety rules in the manual and
the associated safety practices specified by their company, national and regional regulations.
Company, national or regional regulations must be fulfilled beyond HAEFELY recommendations.
This system produces hazardous voltages that can causes in shocks, burns or death. It is the
responsibility of the personnel to ensure that the system is operated in a safe manner.
HAEFELY and its sales partners refuse to accept any responsibility for consequential or direct
damage to persons and/ or goods due to none observance of instructions contained herein or
due to incorrect use of the equipment.
3.1.1 Five basic safety regulations
At any entering or working with high voltage systems always consider the five basic safety
regulations:
1) Disconnect mains!
2) Prevent reconnection!
3) Test for absence of harmful voltages!
4) Ground and short circuit!
5) Cover or close off nearby live parts!
After high voltage tests have been performed the first thing during entering high voltage parts are
should be grounded. A manual ground rod has to be used. In some configurations a recurring
voltage on capacitor can appear also after earthing. In these cases a second ground rod can help
to reduce that risk.
