9.2 Safety Tests after Repair
Attention!
After every repair or dismantling the enclosure, the autoclave should pass two
electrical safety test by the qualified Service Engineer. The following shall be
performed:
1. Enclosure Leakage Current Test.
Every autoclave should pass this test as follows:
1. Connect the electrical cord to the autoclave.
2. Turn ON the main switch on the right side of the autoclave.
3. Short-circuit the L and N pins on the cord's plug.
4. Connect the Short-circuit pins to the L pole on the Megaohm Tester.
5. Connect the earth pins to the earth pole on the Megaohm Tester.
6. Impose an electrical potential of 500–1000V on the tested autoclave.
The insulation resistance should be at least 2 MΩ.
The test is successful if there was no leakage.
2. Protective Earth Impedance Test
1. Connect the grounding pin of the power cord plug to one pole of an
Ohmmeter.
2. Connect any other metallic part (preferable – the metallic part of the
locking screw) to the second pole of the Ohmmeter.
3. The resistance should not exceed 0.3 Ω.
After performing these tests, the Service Engineer should complete and sign the
Work Order and the Log Book.
Warning!
It is strictly forbidden for any person to enter the service area behind the service
access panels, except the trained technician.
If, for any reason it is necessary to open the service access panel, the person
must shut the system by pressing the emergency switch, withdrawing the key and
keeping the key on him, to prevent accidents and injuries.
The technician must follow the instructions in the SERVICE INSTRUCTIONS,
