Functional and electrical safety checks: Electrical safety tests
8-10 Dash 3000/4000/5000 2000966-542D
NOTE
*The MD represents the network and voltage measuring instrument
and its frequency characteristics per IEC 60601-1.
1. Configure leakage tester as follows:
Polarity – NORMAL
Neutral – CLOSED
GND (Earth) – CLOSED
2. Power on device under test.
3. Read and record the current leakage indicated on tester.
NOTE
Center-tapped and non-center-tapped supply circuits produce
different leakage currents and the UL and IEC limits are
different.
4. Change leakage tester switches to:
Polarity – NORMAL
Neutral – OPEN
GND (Earth) – CLOSED
5. Read and record the current leakage indicated on the tester.
6. Change leakage tester switches to:
Polarity – NORMAL
Neutral – CLOSED
GND (Earth) – OPEN
7. Read and record the current leakage indicated on the tester.
8. Change leakage tester switches to:
Polarity – REVERSED
Neutral – CLOSED
GND (Earth) – OPEN
9. Read and record the current leakage indicated on the tester.
10. Change leakage tester switches to:
Polarity – REVERSED
Neutral – OPEN
GND (Earth) – CLOSED
11. Read and record the current leakage indicated on the tester.
12. Change leakage tester switches to:
Polarity – REVERSED
Neutral – CLOSED
GND (Earth) – CLOSED
