CAUTION: For continued safety, replace safety critical
components only with manufacturer's recommended
parts (refer to parts list).
ponents. For continued protection against risk of fire,
replace only with same type and rating fuse(s). To reduce
the risk of electric shock, leakage-current or resistance
measurements shall be carried out (exposed parts are
acceptably insulated from the supply circuit) before the
