Wiring Diagrams
SERIES CONNECTED SPDs: Units designed to be connected in series with the LED driver for
protection of the modes as listed in the table above. Refer to the connection diagrams to ensure
that the SPD you have chosen is appropriate for the application it is being installed into. These range
versions have internal protection that will disconnect the surge protective components and will not
maintain power to the load. If this situation is undesirable for the application, replace the unit with a
parallel connected type.
PARALLEL CONNECTED SPDs: Units designed to be connected in parallel with the LED driver for
protection of the modes as listed in the table above. Refer to the connection diagrams to ensure
that the SPD you have chosen is appropriate for the application it is being installed into. These
parallel versions have internal protection that will disconnect the surge protective components but
will maintain power to the load – now unprotected. If this situation is undesirable for the application,
replace the unit with a series connected type.
