In principle, the safety instructions that apply to the CPC 100 and its accessories
(refer to "Safety Instructions for CPC 100 and its Accessories" in the CPC 100
Reference Manual) also apply to the CP SB1 . Following, only safety instructions
that exclusively apply to the CP SB1 are listed. Before performing tests using
high voltage, please read the following:
• Do not use the test equipment without a good connection to substation
ground.
• Keep clear from zones in which high voltages may occur. Set up a barrier or
establish similar adequate means.
• Make sure to position the CP SB1 in a safe area.
• Pay attention to the national and the international standards for the safe
operation of high-voltage test equipment (EN 50191, IEEE 510).
• Never touch any terminal without a visible ground connection!
• Before connecting or disconnecting test objects and/or cables, turn off the
CPC 100 by either the POWER ON/OFF switch or the Emergency Stop
button. Never connect or disconnect a test object while the outputs are
active.
Note: Even if you switched off the CPC 100 , wait until the red I/O warning
light is fully extinguished. As long as this warning light is lit, there is still
voltage and/or current potential on one or more of the outputs.
• Make sure that the test object's terminals that are to be connected to the
CP SB1 or CPC 100 do not carry any voltage potential. During a test, the only
power source for a test object may be the CPC 100 .
• Do not insert objects (for example screwdrivers, etc.) into any input/output
socket.
• When measuring the ratio of power transformers make sure that the test
voltage is connected to the corresponding high-voltage winding, and the
voltage of the low-voltage winding is the one that is measured. Accidentally
mixing up the windings can generate life-threatening voltages within the
transformer.
