Maintenance: Electrical Safety Tests
Enclosure Leakage Current Test
Perform this test to measure current leakage through exposed conductive
surfaces on the device under test during normal operation.
1.
Set the leakage tester switches as follows:
Selector knob - 2,
GND switch - OPEN, and
Polarity switch - NORM.
2.
Connect a meter lead between the CHAS connector on the rear of the
leakage tester and an unpainted, non-anodized chassis ground on the
unit under test.
3.
Set the leakage tester power switch to ON.
4.
Read the current leakage indicated on DMM. If the reading is greater
than the appropriate specification below, the device under test fails
and should be repaired and tested again.
300 microamperes (0.3 volts on the DMM), and the device under
test is powered from 100-120 V/50-60 Hz
300 µA (0.3 volts on the DMM), and the device under test is
powered from a centered-tapped 200-240 V/50-60 Hz, single
phase circuit
500 µA (0.5 volts on the DMM), and the device under test is
powered from a non-center-tapped, 200-240 V/50-60 Hz, single-
phase circuit
127(
Center-tapped and non-center-tapped circuits produce different
leakage currents and the UL and IEC limits are different.
5.
Set the polarity switch to RVS and observe the same meter readings
as in the previous step.
6.
Set the GND switch on the leakage tester to CLOSED.
7.
Read the current leakage indicated on DMM. If the reading is greater
than the appropriate specification below, and the device under test is
powered from 100-240 V/50-60 Hz, the device under test fails and
should be repaired and tested again.
100 microamperes (0.1 volts on the DMM), and the device under
test is powered from 100-240 V/50-60 Hz
