Always de-energize the PV equipment contacts before attaching the test leads and clips.
For example, when testing in a PV combiner box, open the disconnect switch and lift all
the fuses before attaching the test leads and clips.
Always wear electrical PPE when connecting, disconnecting, or repositioning the test
leads and clips.
For optimum safety, wherever possible do not handle the test leads and clips while they
are energized by the PV source circuit.
Do not use the test leads and clips when it is raining or misting.
Clean the test leads and clips with a moist cloth only. Do not use solvents or soaps.
Using PV Connector Saver Jumpers
PV connectors, regardless of manufacturer, are not designed for large numbers of
connection/disconnection cycles. For this reason, the PVA-1500xx is shipped with
connector-saver jumpers attached to its own PV connectors. The connector-saver jumpers
are intended to take wear and tear, greatly extending the life of the PV connectors on the
test leads and the PVA-1500xx itself. Leave the connector-saver jumpers connected to
the PVA-1500xx’s primary PV leads at all times. Make all your PV circuit
connections/disconnections to the connector-saver jumpers, not to the PVA-1500xx
connectors.
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-
1500xx 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 you 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.
