indicates safety critical compo-
nents. 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 appliance is returned to the customer.
The DC voltage is an
actual reading mea-
sured with a high
impedance type volt-
meter with no signal
input. The measurement
value may vary depend-
