Check the function and safe-
ty of the electrical system.
A qualified electrician should carry
out this inspection. (Refer to the
"Electrical connection" section in the
"Installation" chapter.)
Periodic inspections can
be carried out at intervals
based on the risk as-
sessment which you
conduct for your end
product.
Look over the housing peri-
odically for any signs of
damage.
Check the housing for breaks or
