Indicates safety critical components. 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.• DC voltages are as measured with a high impedance voltmeter. Values may vary slightly due to variations between individual instruments or/and units.
