Disclaimer: In case of a connector replacement, the
warranty applies only to the functionality of the DAS
Energy PV module under exclusion of the connector
which has been replaced. DAS Energy is not liable for
any damage resulting from improper assembly or
non-compliance with the instructions for assembly and
installation of the alternative connector.
It is only allowed to connect a plus (+) coded connector to
a minus (-) coded connector. Please observe the polarity
marking on the connectors (polarity symbol), which can
be seen on the housing (see Fig. 7). Connectors with iden-
tical polarity markings must not be connected together
under any circumstances (plus to plus or minus to minus).
Connecting connectors of different polarity is done by
plugging them together. A clearly audible click should be
heard when the connectors are properly plugged togeth-
er. This signals that the electrical connection is locked and
engaged. When the connectors are correctly connected,
the latches of the positive connector should be flush with
the latches of the negative connector (see Fig. 8).
Please use the corresponding TE connectivity MC4-
Evo2 hand application tool (PN 1971903-1) for discon-
necting the MC4-Evo2 coupler connection. Without this tool there is the potential of damage to the MC4-Evo2
connectors of both male and female.
The locking mechanism of the MC4-Evo2 coupler con-
nection is opened by depressing the latches with the
hand application tool as shown in Fig. 9. Then, discon-
nect the coupler connection while the special tool inser- tion into the locking mechanism to depress the latches,
and pull the couplers apart. Attention: Open couplers
must be protected against the penetration of dirt and
dust by means of protective dust caps.
