related processes of cables and connectors, the force applied between cables and connectors shall not be more than
90N, so as to avoid improper connection or damage of connectors and cables caused by human factors, affecting the
electrical safety or service life of products.
Ensure that all electrical components are in a proper, dry and safe condition. In this way you avoid electrical short-
circuits or dangerous contact voltages due to defective or damaged cables.
Always avoid mechanical stressing of the connection cables.
Ensure a tight connection between the individual connectors (especially to the inverter). Make sure they click together
properly.
4.4 GROUNDING
The module frame must be properly grounded. The grounding wire must be properly fastened
to the module frame to assure good electrical contact. Use the recommended type, or an
equivalent, connector for this wire.
Polarity negative ground of the inverter in the system is able to effectively avoid the PID
phenomenon of the module in addition, and professional person is needed to undertake the polarity negative ground
operation of the inverter.
If the support frame is made of metal, the surface of the frame must be electroplated and have excellent conductivity.
Grounding clip assembly (TYPE: TYCO ELECTRONICS 1954381-2).
Wire selection and preparation:
The grounding clip accepts solid uninsulated copper wire sizes 10 or 12 AWG. The wire must not be nicked, cut, or
scraped. There is no preparation required.
Spacing:
Care must be used to avoid interference between adjacent grounding clips and other components for removal of the
grounding clip.
Removal:
The wire can be removed from the grounding clip when the slider is disengaged (slider and screw are exposed). The
screw must be loosened before the grounding clip can be removed from the frame. The grounding clip can be reused
up to 5 times after proper removals (the 8--32 screw and hex nut or Keps nut can be reused; however, the thread-
cutting screw must be replaced). The thread-cutting screw cannot be reused after removing the grounding clip from
the frame.
Repair:
The grounding clip is not repairable. Discard any defective or damaged grounding clips.
Tooling:
A drill bit is required for drilling the frame holes. A No. 2 cross--recessed screwdriver must be used to secure (and
remove) the screw of the grounding clip to (and from) the frame. For the grounding clip with the 8--32 screw and hex
nut or Keps nut, a 3/8--in. wrench must be used to secure (and remove) the nut of the grounding clip to (or from) the
