Electric Safety Tester and measurements
Picture: example for electric safety tester based on IEC 60601-1.
For all measurements read operation manuals of the measurement
devices carefully and verify the values and intervals with the local
guidelines and laws. An appropriate inspection record for all
measurements and instructions are available at the manufacturers. See
also detailed instruction and protocol form order no. [cos11690xx]. At
first installation at the customer’s site and before first commissioning of
the running machine device, the „first measured values“ have to be
determined and recorded on a special protocol [cos11690xx] and
marked with „first measured values“.
During each preventive maintenance and/or regular maintenance and/or also after each repair work on the device
(even if it was only mechanical repair work!) all above mentioned electric safety measurements and checks (see
protocol [cos11690xx]) have to be performed again. All values have to be compared with the „first measured
values“ and allowed range of tolerance specified according to VDE 0701/0702 (sports and fitness machines) or
VDE 0751/IEC 60601-1 (medical devices).
In case any or more of the measured values is/are not within the allowed range of tolerance specified according to
VDE 0701/0702 (sports and fitness machines) or VDE 0751/IEC 60601-1 (medical devices), the device has to be
repaired until the values are within the specified allowed range of tolerance. In case the device can not be repaired
accordingly and immediately, the device has to be marked and secured against operation and the supplier and
authorized service personnel has to be informed in writing.

Building installation: Electric Checks, Protective Earth Function, RCD, Leakage Current
The customer/operator has the operator duty to check the building installation (electrical installations and
stationary installations) in regular intervals according to regulation BGV A3 of the professional association
respectively information of legal accident insurance every 4 years, on their own response and expenses, for
functions and safety of the complete electrical building installation. At operating sites or rooms of special function -
such as e.g. climate chamber, pressure chamber, installation with special endangering, etc. - the interval is
prescribed one year or shorter if applicable.
In any case use ground wire plugs with tested ground wires only. Existent earth leakage current protection
switches (so called RCD or "residual-current-operated protective device") at the building installation must be tested
by the customer/operator monthly (button at RCD switch in fuse box of the building installation) for correct and
proper function. As a rule the RCD switches at the fuse box are labelled with "press monthly".
Normally a button at the RCD switch has to be pressed for testing (not the "main handle"). With that an earth
leakage current is simulated. The RCD switch must then switch-off the complete electricity supply. These tests
must be carried out by the customer/operator at a time, when the normal operation is not disturbed, all electrical
devices and computers are switched off and nobody is endangered.
Due to the test of the RCD switch it possibly comes, depending on the circuit of the building electricity, to a switch-
off of the complete or a part of the power supply of the building.
