Setting Up the Test
1. If you apply a second CP CR500 unit, connect it to the Safety B connector of
the first CP CR500 unit using the second modem-cable (length 9 m). Close
the Safety B connector on the second unit with the CPC 100 dongle.
2. Connect both CP CR500 units to the test object using the high-voltage
cables (4-4 ”Connecting two CP CR500 units in parallel”).
3. Connect both low-voltage LV connectors to each other using the delivered
standard connection leads 1 x 2 m x 2.5 mm² (black).
