Prior to installation, survey the site for information regarding power and accessibility inside and outside the building. Ensure
that the branch circuit supplying the existing transformer or ballast will be within the voltage ratings of the new LED power
supply, and have a current rating not exceeding 20A, or that permitted by applicable local, state, or country electrical codes
(whichever is less).
If removal of the existing lighting equipment (see Step 2) eliminates the disconnect switch, as required by applicable local,
state, or country electrical codes; a new disconnect switch must be installed.
If required, the disconnect switch shall be installed by qualified personnel, in accordance with applicable local, state, and
country electrical codes.
Repair and seal any unused openings in the electrical enclosure. Openings greater than 12.7-mm (1/2-in) diameter require a
metal patch secured by screws or rivets and caulked with non-hardening caulk. Smaller openings may be sealed with non-
hardening caulk.
