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
measured with a high impedance type
voltmeter with no signal input. The
measurement value may vary depend-
ing on the measuring instruments used
or on the product.
