General InstallationInstallation Manual 352.2.5 Frame Ground ConnectionIMPORTANTConnect the frame of the main unit to ground.1. Loosen the screw.2. Insert the grounding wire.3. Tighten the screw.4. Connect the grounding wire to ground.In most of the continental United States, the ground provided by the "Third wire ground" at thecommercial power outlet will be satisfactory. However, in a small percentage of cases thisground may be installed incorrectly. Therefore, the following test procedure should beperformed.Test Procedure1. Obtain a suitable voltmeter and set it for a possible reading of up to 250 V AC.2. Connect the meter probes between the two main AC voltage points on the wall outlet. Thereading obtained should be 108 V AC-132 V AC.3. Move one of the meter probes to the 3rd prong terminal (GND).Either the same reading or a reading of 0 V should be obtained.4. If a reading of 0 V at one terminal and a reading of 108 V AC-132 V AC at the other terminalis not obtained, the outlet is not properly grounded.This condition should be corrected by a qualified electrician (per article 250 of the NationalElectrical Code).5. If a reading of 0 V at one terminal and a reading of 108 V AC-132 V AC at the other terminalis obtained, then set the meter to the "OHMS / RX1" scale, place one probe at the GNDTerminal and the other probe at the terminal which gave a reading of 0 V.A reading of less than 1 ohm should be obtained.To groundPanasonicD816DIGITAL SUPER HYBRID SYSTEMTo groundA1232ADVANCED HYBRID SYSTEM KX-TA1232
