10 - 22 Section 10-6 - Electrical Safety Tests
10-6-2 Leakage Current Limits
The following acceptance limits and test conditions are summarized from NFPA 99 and IEC 62353 and
in some cases are lower than that specified by the standards.
In accordance with these standards, fault conditions like Reverse Polarity of the supply mains and Open
Neutral are no longer required for field evaluation of leakage current. Because the main source of
leakage current is the mains supply, there are different acceptance limits depending on the
configuration of the mains (100-120VAC or 230-240VAC).
WARNING WARNING
ENERGY CONTROL AND POWER LOCKOUT FOR VIVID E9.
WHEN SERVICING PARTS OF THE SYSTEM WHERE THERE IS EXPOSURE TO
VOLTAGE GREATER THAN 30 VOLTS:
1. FOLLOW LOCK OUT/TAG OUT PROCEDURES.
2. TURN OFF THE BREAKER.
3. UNPLUG THE VIVID E9.
4. MAINTAIN CONTROL OF THE POWER PLUG.
5. WAIT FOR AT LEAST 20 SECONDS FOR CAPACITORS TO DISCHARGE, AS THERE ARE NO TEST POINTS TO
VERIFY ISOLATION. THE AMBER LIGHT ON THE OP PANEL ON/OFF BUTTON WILL TURN OFF.
BEWARE THAT THE MAIN POWER SUPPLY AND BACK END PROCESSOR MAY BE ENERGIZED EVEN IF THE POWER
IS TURNED OFF WHEN THE CORD IS STILL PLUGGED INTO THE AC OUTLET.
CAUTION
Compare all safety-test results with safety-test results of previously performed safety tests (e.g.
last year etc). In case of unexplainable abrupt changes of safety-test results consult
experienced authorized service personnel or GE for further analysis.
