Testing Procedure

1.All connections shall be representative of the recommended field wiring installation , and precautions shall be taken to ensure that leakage currents do not originate from the instrumentation wiring attached to the module

2.Immerse the module in the tank of the required solution to a depth sufficient to cover all surfaces except      

junction box entries not designed for immersion. If not immersed the cable entries shall be thoroughly sprayed with solution, if the module is provided with a mating connector, the connect should be sprayed during the test.

3.Connect the shorted output terminals of the module to the positive terminal of the test equipment , connect  

the liquid test solution to the negative terminal of the test equipment using a suitable metallic conductor

4.Connect the shorted output terminals of the module to the positive terminal of the test equipment, connect the liquid test solution to the negative terminal of the test equipment using a suitable metallic conductor

5.Some module technologies may be sensitive to static polarization if the module is maintained at positive voltage to the frame, in this case , the connection of the tester shall be done in the opposite way, if applicable, information with respect to sensitivity to static polarization shall be provided by manufacturer

6.Increase the voltage applied by the test equipment at a rate not exceeding 500V/s to 500V or the maximum system voltage for the module , whichever is greater. Maintain the voltage at this level for 2min, then determine the insulation resistance

7.Reduce the applied voltage to zero and short-circuit the terminals of the test equipment to discharge the  voltage build-up on the module

8.Ensure that the used solution is well rinsed off the module before continuing the testing
