connected to the PV output.

4.1.5 Refer to Section 690-8 of the National Electrical Code for an additional multiplying factor

of 125%（80% derating） which may be applicable.

4.1.6 Each module (or series-connected string of modules) shall be provided with the maximum

series fuse, specified 15A for modules with I

4.1.7 Use a special solar cable and plugs for installing the PV system and make sure that all

connections are safe and tight. The cable should be 4 mm

withstand the maximum possible system open-circuit voltage.

4.1.8 Bypass diodes are included in module junction boxes to avoid decreased module

performance in the event of shade. Please check the relevant product datasheet for the

specific diodes of J-box.

4.1.9 Prohibit interconnection between different types of connectors.

4.2 Grounding

4.2.1 The grounding requirements must be checked in accordance with the applicable

regulations and standards before work is started.

4.2.2 Use the marked 5.5 mm grounding holes to ground the anodized frame. Use one M5 nut,

two M5 cut washers, one M5 plain washer, one M5 spring washer, and one M5 bolt and

the copper wire. All nuts, bolts, and washers are type M5 and should be made of

stainless steel (Fig. (n) ).

4.2.3 Put the bolt through the cup washer and wrap the copper wire around the bolt. (Note that

the copper wire cannot be attached directly to the aluminum.)

4.2.4 Put the bolt through the cut washer and then through the hole in the aluminum frame.

4.2.5 Add the spring washer and nut on the other side of the bolt and tighten to secure all parts.
