High-voltage and high-current outputs
• Use only one CPC 100 output at a time.
• All AC and DC output sockets of CPC 100 can carry life-hazardous voltage
potential and provide life-hazardous currents. Therefore:
– While connecting cables to the CPC 100 high-voltage or high-current
outputs or other conducting parts that are not protected against accidental
contact, press the Emergency Stop button, and keep it pressed as long
as an output signal is not absolutely necessary for the test.
– When connecting to the front panel input/output sockets, use wires with
either 4 mm safety "banana" connectors and plastic housing or, where
applicable, with the especially manufactured counterpart supplied by
OMICRON electronics (for example, for the V2 AC measuring input).
– For the high-voltage and high-current output connectors on the left-hand
side of the test set (2kV AC, 400A DC and 800A AC, ext. Booster), only
use the specially manufactured cables supplied by OMICRON electronics
(refer to ”Cables” on page 17-15).
One end of the high-voltage cable has a coaxial safety plug that is
certified for a voltage level of 2kV AC. The other end is equipped with a
safety banana plug that is insulated with a shrink tube.
When CPC 100 is switched on consider this part of the cable a
hazard of electric shock!
– If you do not use the high-current 400A DC or 800A AC outputs or the
high-voltage 2kV AC output, disconnect any cable that may be plugged
in to these sockets.
The 400A DC or 800A AC outputs are not switched off by internal
relays. Therefore, if a test mode is selected that does not use either
one of these two outputs, they still generate current.
– Do not stand right next to or directly underneath a connection point
because the clamps may fall off and touch you.
This is a physical and an electrical hazard.
– The red warning light on the CPC 100 front panel indicates hazardous
voltage and/or current levels at the CPC 100 outputs (red light "I" on or
flashing). The green warning light indicates that the CPC 100 outputs are
not activated.
– Both of the high-current output sockets on the left-hand side of the test set
(400A DC and 800A AC) usually carry a relatively low-voltage potential.
Note: If none or both warning lights are on, the unit is defective and
must not be used anymore.
