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.
