Check the polarity of each couple of cables that must be connected to the inverter input: mark the cable
corresponding to the positive pole so as to be able to distinguish it from the one corresponding to the
negative pole. In the case of several strings, observe the correspondence between the negative and positive
of each string.
Check the open circuit voltage of each pair of cables which must be connected in input to the inverter: the
value must in no case exceed the maximum input voltage of the inverter. Voltage values which exceed the
permitted levels may irreparably damage the unit. any consequential damage to the inverter is not
covered by the warranty.
In the case of –FS models the input current in each connector must not exceed 12a (internal fuse current limit).
Higher values can damage the fuse. For all the other models the input current limit is 20a for each connector.
Crimp the MC4/WM counterparts to the string cables or the cables from the string disconnecting switches
(external) paying attention to the polarity of the voltage and the connector / terminal.
note: The French standard UTE-15-712-1 requires that supplementary retaining clips are assembled to the input
connectors to avoid the risk of accidental disconnection.
note: These retaining clips are not supplied in the accompanying assembly kit.
The retaining clips can be ordered directly from Power-One, quoting the following codes:
3G830020000 (for Multicontat connectors)
3G830010000 (for Weidermüller connectors)
