Instructions and Conditions
Check all relevant cables for dents, damaged isolation and blank lines.
Move and bend the cables around your hand to slightly stretch the isola-
tion. Any visible damage is not acceptable.
Check Monitor Cart, Camera Cart and EM Tracking Unit (if present) for
visible damage, broken cables and blank lines. With the exception of air
vents, you should not be able to see the interior of the carts. Damaged
cables, blank lines or visibility of the interior are not acceptable.
Check indicator LEDs (on the Monitor Cart, Camera Cart and EM Track-
ing Unit (optional)) for detected errors.
If any damages are detected, place the device out of operation, mark as
such and contact Brainlab support.
Plug Monitor Cart into mains power supply using the original Brainlab
mains power cable. If you have multiple mains power cables for your de-
vice, repeat this test with each cable.
Test the protective earth resistance according to IEC 62353:2007 Chapter
5.3.2.2 using a measuring device capable of delivering a current of at
least 200 mA into 500 mΩ. Perform measurement for one second. The
open circuit voltage must not exceed 24 V.
Connect Monitor Cart and Camera Cart using the camera cable. Plug
Monitor Cart into mains power supply using the original Brainlab mains
power cable.
Test the equipment leakage current according to IEC 62353:2007 Chapter
5.3.3.2.3 using the so-called "differential method" with the following addi-
tional conditions:
• Measurements are performed at mains voltage.
• Measurements are performed in both positions of the mains plug, if
possible.
When measuring in the various positions of the mains plug, document the
higher value.
Connect Monitor Cart and EM Tracking Unit using the provided connec-
tion cables. Plug Monitor Cart into mains power supply using the original
Brainlab mains power cable.

mains power cable.
Test the equipment leakage current according to IEC 62353:2007 Chapter
5.3.4.3.2 using the so-called "alternative measurement", see Image 9 in
IEC 62353.
