screws when replacing the power supply cover, and
also so they do not interfere with fan operation.

signs.
InView signs are for indoor use only and should not
be continuously exposed to direct sunlight.
Mounting hardware that is used to hang or suspend
signs must be capable of supporting at least 4 times
the total weight of any/all signs mounted together.
For integrity of the case, do not drill holes in or
modify the case.
