3.3.3.6. DC Connection for H4 Wiringbox
This section addresses the DC connections to the H4 wiringbox. If
the Standard wiring box is used reference Section 3.3.3.5.
1. Always verify polarity before terminating the PV conductors to
avoid risk of reverse polarity.
2. Cable preparation and stripping process: Strip the cables
0.276 inches (7.0 mm) and be careful not to nick conductor
strands.
Amphenol’s specified strip tool (H4TS0000) can be used in this
step (contact Amphenol retailer to purchase this tool). Adjust the
stripper stopper and insert the cable in the corresponding notch
to strip to 0.276 inches (7.0 mm) length.

NOTICE:
The Amphenol H4 connectors provided within the Accessory Kit must
be used for the DC input with the H4 wirebox. Male and Female H4
connectors with 14awg contact pins are provided. Other wire sizes
require replacing the connectors/contact pins provided. Use of
incompatible connector types may create an improper contact and
cause faults and/or loss of production requiring servicing of the
inverter and installation.
