Maintenance:
Domestic Electrical Safety Tests
Leakage Tests
The leakage tests are safety tests to ensure that the equipment poses no
electrical health hazards. Use the table below to determine which tests
apply to the unit under test and the maximum allowable leakage
currents. For international leakage limits, refer to the internal standards
agencies of that particular country.
If the unit under test fails the leakage tests, do not allow the customer to
use the equipment. Call Tech Support for assistance. (See the “How to
Reach Us” page in the front of the manual.)
We recommend that you perform these tests:
Before applying power for the first time
Every 6 months as part of routine maintenance
Whenever internal assemblies are serviced
NOTE
The accuracy of the leakage tests depends on the properly-
wired wall outlet. Do not proceed until you verify the
integrity of the power source.
WARNING
Total system leakage must not exceed 300 microamperes
(United States) or 500 microamperes (international).
