4.1 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 written in this document and the associated safety practices
specified by their company and government. Local and state safety procedures should also be consulted.
Company and government regulations take precedence over Haefely Test AG recommendations.
The MIDAS micro 2883 generates high voltage and is capable of causing serious or even lethal electrical shock. If
the instrument is damaged or it is possible that damage has occurred, for example during transportation, do not
apply any voltage.
The instrument may only be used under dry operating conditions. The use of MIDAS is prohibited in rain or snow.
Do not open the MIDAS micro 2883, it contains no user replaceable parts.
Do not switch on or operate a MIDAS micro 2883 instrument if an explosion hazard exists.
4.2 Personnel Safety
The MIDAS micro 2883 should not be operated by a crew smaller than two people. Their function can be described
as follow:
Test Operator: The person who is making the test connections and operates the MIDAS micro 2883. He must be
able to have a clear view of the device under test and the area where the test is performed.
Safety Observer: The person who is responsible for observing the performance of the test, seeing any safety
hazard, and giving warning to crew members.
Both persons should perform no other work while the MIDAS micro 2883 is energized.
While making the various types of connections involved in the different tests, it may be necessary for personnel to
climb up on the equipment, but no one should remain on the equipment during the test itself.
Non-test related persons who are working in proximity to the area where testing is performed must be informed.
Consistent visual and verbal signals should be agreed and followed.
Perform only one job at a time on any equipment. The situation in which two crews are doing different tasks with
the same equipment at the same time is an open invitation for confusion, trouble, and danger to the personnel.
