Attention:
Always ensure that the circuit under test is electrically isolated from
the mains supply.
Tip:
Due to the high input impedance of the red 4 mm test terminal,
voltage caused by leakage currents may be detected on the prior to
starting a test.
Tip:
During the insulation test, the EazyPV applies a short circuit across
the PV-string. The insulation test voltage is then applied between the
red 4 mm test lead and the two PV-testterminals.
Tip:
If the DC-voltage polarity is incorrect or the voltage is < 5 V or >1000 V
the Autotest will be inhibited until the problem is corrected.
