18、 a repair: Connect the unit to the mains via an isolation transformer. Replace safety components, indicated by the symbol ,only by components identical to the original ones. Anyother component substitution (other than original type) may increase risk of fi re or electrical shock hazard.Safety regula
19、tions require that after a repair, you must return the unit in its original condition. Pay, in particular, attention tothe following points: Route the wires/cables correctly, and fi x them with themounted cable clamps. Check the insulation of the mains lead for externaldamage. Check the electrical D
20、C resistance between the mains plug and the secondary side:1. Unplug the mains cord, and connect a wire betweenthe two pins of the mains plug.2. Set the mains switch to the on position (keep themains cord unplugged!).3. Measure the resistance value between the mains plug and the front panel, control
21、s, and chassis bottom.4. Repair or correct unit when the resistancemeasurement is less than 1 M.5. Verify this, before you return the unit to the customer/user (ref. UL-standard no. 1492).6. Switch the unit off, and remove the wire between the two pins of the mains plug.2.1.2 Laser SafetyThis unit e
