1.2.3 Safety accessories
OMICRON offers a range of accessories for added safety during the operation of our test systems. For
further information and specifications, refer to the corresponding Supplementary Sheet or contact
OMICRON Support.
1.3 Grounding
Operating the device without PE and ground connection is life-threatening and not permitted.
► Only operate CIBANO 500 with a mains power supply connected to protective earth (PE).
► Make sure that both the PE connection of the power supply and the ground connector of CIBANO 500
have a solid and low-impedance connection to the grounding system on site.
This also applies to all other test devices and accessories in the test setup.
► Make sure that the grounding clamp has a good electrical contact to the grounding system on site
and avoid connecting it to corroded or painted surfaces.
► Make sure that the grounding terminal connections of all grounded devices in use remain intact
during the whole measurement procedure, and are not accidentally disconnected.
► Only use ground and supply cables provided by OMICRON.
1.4 Power supply
Operating CIBANO 500 without PE and ground connection is life-threatening and not permitted.
► Only operate CIBANO 500 with a mains power supply connected to protective earth (PE).
Power supply from grounded grids (TN/TT)
Before a measurement is started, CIBANO 500 automatically verifies the PE connection in grounded
grids (TN/TT).
► If this check fails, check the power cord and power supply.
If the error message persists, there is no intact connection to protective earth (PE).
This is life-threatening. In this case measurements are not permitted and cannot be performed.
Connect the CIBANO 500 grounding terminal to the grounding system on site.
