Grounding 10; Maintenance And Disposal - Jinergy JNMP60 series Installation Manual

ents of the National Electrical Code (NEC) in Article 690 shall be followed to address these
increased outputs. In installations not under the requirements of the NEC, the values of Isc and
Voc marked on this module should be multiplied by a factor of 1.25 when determining coonductor
capacities, over current device ratings, and size of controls connected to the PV output.
4.1.5 Each module (or series-connected string of modules) shall be provided with the maximum
series overcurrent protective device, specified as 15A for the 6 inch cell module series.
4.1.6 Use a special solar cable and plugs for installing the PV system and make sure that all
connections are safe and tight. The cable cross section size should be 4mm (12AWG) and able
to withstand the maximum possible system open-circuit voltage.
4.1.7 Bypass diodes are included in module junction boxes to avoid decreased module perfor-
mance in the event of shade or shelter. Please check the relevant product datasheet for the
specific diodes of J-box.

Frame
Ground wire
Fastening bolt
Grounding the aluminum frame with copper wire
4.2.1 Use the marked 5.5mm grounding holes (5.5mm) to ground the anodized frame. Use an
M5 nut, an M5 gasket, and an M5 bolt, Fastening bolt and a Ground wire. All nuts, bolts, and
gasket are type M5 and should be made of stainless steel (Fig.h).
4.2.2 Fixed Ground wire on Fixed end through fastening bolt. (Note that the copper wire cannot
be attached directly to the aluminum).
4.2.3 Put the bolt through the Fixed end and then through the hole in the aluminum frame.
4.2.4 Add the gasket and nut on the other side of the bolt and tighten to secure all parts. The
tightening torque should be 2.1±0.1Nm.

5.1 Regularly carry out a visual inspection for dirt, dust, bird dropping, leaves, and other
detritus covering the modules.
5.2 If there is a buildup of dirt or dust on the module surface, wash the module with clean water
and a gentle implement (a sponge). Never use chemicals on the surface of the module.
5.3 If snow is present, a soft-bristled brush with soft bristles may be used to clean the surface
of the modules.
5.4 Regular electrical and mechanical inspection by a licensed professional will keep the
system safe and operating at maximum efficiency.
