Electrical Safety Test
The Electrical Safety Test must be performed twice .
A
The first test will ensure the PE and Insulation Resistance are acceptable for safe AC power application .
The second test, with the Workstation powered up from AC power, is to ensure the Leakage Current values are
correctly measured .
Electrical Safety Test Calibration
Note: Ensure that no physical contact is made with the unit under test during the electrical safety test cycle .
1 . Connect a Medical grade electrical safety tester, (e .g . Safety Tester) to a main's outlet, ensuring that the connections for Live and
Neutral are correct .
2 . Connect the enclosure lead to the PE point of the Workstation . Plug the mains test lead from the safety tester into the Workstation
mains inlet .
3 . Switch on the Workstation .
4 . Set up and perform a standard electrical safety test to IEC/EN60601-1 Class I, using an Earth Continuity test current of 25A . If the
safety tester requires an applied Type to be entered, select Type B but no applied parts should be specified .
The required test result limits are as follows:
• Current Consumption
• Protective Earth Resistance (all test points)
Earth Leakage Current:
• Open Supply (OS)
• Normal Condition (NC)
• Open Supply Reverse Mains (OSRM)
• Normal Condition Reverse Mains (NCRM)
Enclosure Leakage Current:
• Open Supply (OS)
• Normal Condition (NC)
• Open Earth (OE)
• Open Supply Reverse Mains (OSRM)
• Normal Condition Reverse Mains (NCRM)
• Open Earth Reverse Mains (OERM)
First Electrical Safety Test
PE Connector - Earth Continuity Test
1 . Connect the AC lead from the Safety Tester to the Workstation Mains Inlet .
2 . Connect the enclosure lead from the Safety Tester to the PE stud on the rear cover of the Workstation with a crocodile clip .
3 . Perform the Earth Continuity Test .
4 . Disconnect the enclosure lead from the PE stud .
