CAUTION When the lifetime of the connector-save jumpers has been reached (typically 100
connection/disconnection cycles), remove them, cut them in half to prevent further use,
and recycle them. Replace them with fresh connector-saver jumpers, which can be
ordered from Solmetric.
Using the connector-saver jumpers as described here will extend the life of the PVA-600
+
PV connectors by 100 times.
PV/Electrical Safety Precautions
Installed PV systems are not consistent in design or construction. Therefore, the guidance
provided in this section is general in nature, and it is critical that the user apply
techniques and precautions appropriate to the circumstances, following best PV/electrical
safety precautions.
WARNING The information below is important but not necessarily complete; the operator must
assess the potential dangers of each PV system, and take appropriate precautions.
FAILURE TO TAKE APPROPRIATE SAFETY PRECAUTIONS COULD LEAD
TO PERSONAL INJURY OR LOSS OF LIFE.
•
Never work alone.
•
Do not use the PVA-600
+
in wet environments.
•
Do not operate or subject the PVA-600
+
to temperatures beyond the published
operating and storage temperature specifications.
•
Wear electrical safety gloves.
•
Wear eye protection.
•
Wear fall protection where required.
•
Assume that metal surfaces are energized unless proven otherwise.
•
Isolate the PV source circuit under test from the inverter, and from other PV
source circuits, before making any connections to the test device (PV module,
string, or array).
•
Always pause the measurement sequence using the LED-illuminated pushbutton
switch on the I-V unit before connecting or disconnecting the test leads of the
PVA-600
+
.
•
Do not use the PVA-600
+
to test devices that produce more than the instrument’s
specified maximum current and voltage.
•
Connect the test leads to the test device (PV module, string, or array) with the
correct polarity.
