The 6″ violet leads provide the lamp selection option. The unit is shipped from the factory with the leads discon-
nected and capped.
2. MOUNTING THE I-42-EM-A
When used with ceiling mounted downlight fixtures, the I-42-EM-A should be mounted on the fixture above the
ceiling. The flex conduit marked “A” should be wired into the ballast/lamp compartment or to an electrical junction
box on the fixture which allows access to the ballast/lamp connections. Refer to Illustration 1 for typical mounting.
When battery packs are remote mounted, the remote distance can not exceed ½ of the distance from ballast to
lamp specified by the A.C. ballast manufacturer. For example, if the A.C. ballast manufacturer recommends no
more than 25′ remote distance, then the battery pack should not exceed 12½′. Under no circumstances should
the battery pack exceed a distance of 50′ from the lamp.
