帮我翻译一些UL1598这段话。

UL1598 CLS6.14.2.4: a luminaire required to be grounded in accordance with clause 6.14.1.1 and designed for mounting over an outlet box, but not incorporating a means to terminate the branch circuit grounding conductor, shall be provided with a mounting crossbar that has a grounding termination means

大致意思是，如果灯具被要求接地，而在canopy那里没有提供接地线来连接建筑物里的地线，则需要额外提供一个corssbar（一字铁或者八卦铁之类），并且要在crossbar上提供一个锁接地线的接地螺丝。
