Hi-Pot Test
THIS IS A MANDATORY TEST
CAUTION - All units that are disassembled
as part of a repair MUST be Hi-Pot tested
before being returned to the customer.
This test applies a high voltage to the AC
line cord and measures the current leakage
to the chassis and/or other metal parts on
the outside of the unit to check for potential
shock hazards.
- If the unit fails Hi-Pot test, it must be
rerturned to the technician for troubleshoot-
ing and repair of the problem, after which it
must be Hi-Pot tested again to ensure that it
now passes the test.
- This test requires a Hi-Pot tester and
associated cables to perform this test. There
is a PDF file located on the L1 Model 1S
product specific page on the Bose Service
web site that details how to perform this test.
Hi-Pot Tester Settings:
100-120V units: Voltage Setting =
2.12KVDC, High Current = 3.5ma, Low
Current = 0ma, Ramp Time = 1 Second,
Dwell Time = 1 Second, Continuity OFF
220-240V units: Voltage Setting =
3.54 KVDC, High Current = 3.5ma, Low
Current = 0ma, Ramp Time = 1 Second,
Dwell Time = 1 Second, Continuity = OFF
1.1 Connect the AC mains cord to the back
of the unit under test. Plug the other end of
the AC cord into the Hi-Pot tester.
Connect the Return lead to the Analog Input
jack using an adapter and cable.
1.2 With the tester set to the above param-
eters, perform the test. If the unit fails,
return the unit to the technician for trouble-
shooting and and repair of the problem.
Once the unit is repaired, repeat the Hi-Pot
test to ensure the unit is safe to return to the
customer.
