3.5.2 Performing leakage current testing
If ground testing is required for this system, verify that the ground testing results (see Table 3-3 ) are
< 0.1 Ohms before conducting leakage testing.
Leakage testing must be performed if the AC power plug has been replaced or disturbed.
The leakage current must not exceed 300 uA.
Before you begin, verify these steps:
1. Complete ground testing, if required (see 3.5.1 Performing ground resistance testing on
page 37 ).
2. Ensure that all system covers are installed.
3. Obtain a Dale 601/601E test meter or equivalent.
Perform leakage testing under the five specific conditions outlined in Table 3-4 :
