AC OUTLET TESTS

The following tests verify proper grounding of the ac outlet.

WARNING: Hazardous voltages are present during the following tests. Use great care when working with ac power line voltages.

Check the ac outlet for proper ground with a circuit tester.

NOTE: You may use any generic unit (such as the Ideal 61-035 Circuit Tester) to verify that the outlet is wired properly.

1 Plug an Ideal or equivalent circuit tester into the outlet to be tested. If the circuit is properly grounded, the yellow and white lights on the tester will light.

2 Remove the circuit tester and, if necessary, test another outlet.

NOTE: If the ac outlet test shows an improper ground, do not install the MERLIN II system. Tell the customer to have an electrician correct the problem.

Check the ac outlet for proper ground with a Volt-Ohm- Milliammeter (VOM).

1 Set the VOM to the scale on which you can read 115 VAC.

2 Measure the ac outlet voltages:

>Hot to third-wire ground should be about 115 VAC.

>Neutral to third-wire ground should be less than 2.5 VAC.

3 If the voltage readings do not measure the values suggested, the ac outlet is improperly wired. Notify the customer that an electrician should repair the outlet.
