NOTICE

Maximum Voltage: The open circuit voltage, V

, must never exceed 600 V

under any conditions. The voltage generated by PV modules is inversely

proportional to the temperature; at lower temperatures the PV voltage increases

from the nameplate rating and at higher temperatures the PV voltage decreases

from the nameplate rating.

NOTICE

Ensure the DC switch in the Stringbox is in the OFF position, when removing the
