Cabinet

The clock cabinet requires a 120 VAC, 15 Amp receptacle. The green wire ground provided by the receptacle is sufficient. The clock cabinet does not require a ground connection back to the single-point ground.

5.Verify the meter reads 0 VAC. If not, have a qualified electrician correct the problem.

6.Set all cabinet power modules OFF. Plug the AC power cable into the receptacle.
