IEC 61643-11:2025<\/a> addresses SPDs connected to AC low-voltage power systems. It cautions that connection to a different kind of source requires careful consideration of system and fault conditions. A VFD’s PWM output is precisely the kind of non-standard source that calls for product-specific guidance.<\/p>\n

Start with the building’s service entrance and the distribution board feeding the VFD. The lightning-protection arrangement and installation rules determine whether a Type 1, Type 2 or coordinated combination is appropriate. If the drive is far from the upstream SPD or its input withstand level requires additional protection, assess a suitable downstream AC SPD near the drive’s \u30e9\u30a4\u30f3\u5165\u529b<\/strong>. \u3002\u3053\u308c\u306f\u8a2d\u8a08\u4e0a\u306e\u5224\u65ad\u3067\u3042\u308a\u3001\u3059\u3079\u3066\u306eVFD\u306e\u6a2a\u306b\u8a2d\u7f6e\u305b\u3088\u3068\u3044\u3046\u666e\u904d\u7684\u306a\u6307\u793a\u3067\u306f\u306a\u3044\u3002.<\/p>\n
