3.8 Protection against electric shock
Ensuring protection against electric shock when using DB1 variable
frequency drives, as per IEC/EN 61800-5-1
Manufacturer’s declaration for the initial validation under
IEC/HD 60364-6
(DIN VDE 0100-600 (VDE 0100-600)) and for periodic testing as per
EN 50110-1 (DIN VDE 0105-100 (VDE 0105-100))
Fault protection as per IEC/HD 60364-4-41 (DIN VDE 0100-410 (VDE 0100-410))
for the circuit on the output side of the aforementioned equipment is ensu-
red based on the following requirements:
•
The installation instructions in this documentation have been followed.
•
The applicable standards in the IEC/HD 60364 (DIN VDE 0100
(VDE 0100) series have been observed.
•
The consistency of all associated protective conductors and potential
equalization cables, including their connection points, has been ensured.
Provided that the above requirements are met, the above apparatus meets
the requirements in IEC/HD 60364-4-41 (DIN VDE 0100-410 (VDE 0100-
410):2007-06, section 411.3.2.5) when applying the “automatic power sup-
ply shutdown” protective measure.
The note is based on the following information:
In the event of a short-circuit with negligible impedance to a protective con-
ductor or to ground, the aforementioned equipment reduces the output vol-
tage within the times as per Table 41.1 or otherwise within 5 seconds –
whichever applies - in accordance with IEC/HD 60364-41 (DIN VDE 0100-410;
VDE 0100-410):2007-06).
