HIGH VOLTAGE, DANGER OF ELECTRICAL SHOCK
• The Machinery-Tester MT 204-S supplies high voltage of dangerous
power. According to EN 50191 the following precautionary measures
must be taken prior to a test:
- Block access to danger area.
- Put up warning signs (Attention! High voltage, danger to life).
- Install warning lamps (red, green) to be easily visible.
- Install EMERGENCY-OFF switch into the mains installation outside
the dangerous area.

These notes are just extracts of the EN 50191 standard. The following
notes should be respected, when carrying out the measurements.
• Properly trained persons may only do the tests under supervision of
specialized staff and have to be trained regularly.
• Use safety probes with protection against contact or with two-hand
operation only. Always hold only one probe in one hand.
• Connecting one terminal to the test object and working with one probe
or holding both probes in one hand is prohibited.
• It is prohibited to touch the unit under test during the test. If need be,
additional measures must be taken (e.g. cover made of insulating mats)
to protect the person performing the test against inadvertent contact
with the unit under test.
• Testing may commence only after all safety measures were taken.
• To avoid any risk of use of high-voltage test function "HV" by
unauthorized or not properly instructed personnel, the lock key must be
removed from the key switch (6) when the device is not in use. The key
can be removed in off position only, thus mechanically locking the high-
voltage test function. Other measurement functions remain accessible.
Appropriate usage
• The instrument may only be used under those conditions and for those
purposes for which it was conceived. For this reason, in particular the
safety references, the technical data including environmental conditions
and the usage in dry environments must be followed.
• When modifying the instrument, the operational safety is no longer
ensured.
• The instrument may only be opened by an authorised service technician.
Before opening, the instrument must be switched off and disconnected
from any electrical circuit.
