HIGH VOLTAGe
Contact with high voltage circuits can cause burns, shock, loss of consciousness and even the
victim's electrocution. This may happen due to lack of awareness of the dangers connected with the
use of electrical equipment. The injury suffered by the human body depends on the amount of power
as well as on the duration and path followed by the current inside the body.

• Before servicing the equipment, disconnect all circuits.
• Make sure that no voltage whatsoever is present in the circuit.
• Clean and dry the whole area.
• Remove pins, rings, brackets or any accessories which may hinder operations or turn into a
potential electrical conductor.
• Discharge to earth or short circuit the capacitor terminals connected with the deactivated circuit.
• Remove the safety devices only after the circuit has been deactivated.

• Add the following provisions to those under items 2, 3 and 4 above:
• Personnel must never operate alone;
• If possible, use only one hand to perform work required;
• Check wires and instruments regularly;
• Use only approved procedures to bypass the interlocks;
• Ensure that operators are perfectly familiar with the equipment parts and maintenance
procedures, before servicing the unit;
• Use a pair of safety gloves;
• Open all contacts which feed power to the equipment before measuring resistance levels;
• Check that there is no high voltage in the low voltage circuits;
• Do not use magnetic tools RDXC in the proximity of strong magnetic fields.

• If continuous duty is not required, the system must be turned off.
• Before commencing work, the following is required:
• Check that the maintenance technician is not carrying any objects which may act as conductors;
• Inspect the work area to make sure the floor is clean and dry;
• Check work tools. They must be suitable for their designated task and in good working order so as
to ensure safe maintenance operations
• Check that all gauges are regularly calibrated
• Check servicing procedures before commencing work by inspecting the wiring diagram and
visualising the system structure.
When carrying out electrical maintenance operations, the following is required:
• The maintenance technician must be familiar with high voltage circuits;
• No resistance measurements are to be carried out on live circuits;
• Use only one hand to take measurements on live circuits;
• Earth all instrument terminals before taking measurements on live circuits.
The above recommendations must be strictly adhered to. Maintenance operations shall be deemed
to have been completed only when all parts have been re-installed and the product has regained its
original appearance.
