2.2 Installation of the Hybrid IP-PBX

2.2.5Frame Ground Connection

IMPORTANT

Connect the frame of the Hybrid IP-PBX to ground.

1.

Loosen the screw.

Screw

2.

Insert a grounding wire (user-supplied)*.

 

3.Tighten the screw.

4. Connect the grounding wire to ground.

Grounding wire

To ground

*For grounding wire, green-and-yellow insulation is required, and the cross-sectional area of the conductor must be more than 0.75 mm2 or 18 AWG.

Be sure to comply with applicable local regulations (e.g., laws, guidelines).

Proper grounding (connection to ground) is very important to protect the Hybrid IP-PBX from the bad effects of external noise or to reduce the risk to the user of electrocution in the case of a lightning strike.

The ground wire of the AC cable has an effect against external noise and lightning strikes, but it may not be enough to protect the Hybrid IP-PBX. A permanent connection between ground and the ground terminal of the Hybrid IP-PBX must be made.

In most of the continental United States, the ground provided by the "Third wire ground" at the commercial power outlet will be satisfactory. However, in a small percentage of cases this ground may be installed incorrectly. Therefore, the following test procedure should be performed.

Test Procedure

1.Obtain a suitable voltmeter and set it for a possible reading of up to 250 V AC.

2.Connect the meter probes between the 2 main AC voltage points on the wall outlet. The reading obtained should be 108 V AC to 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 volt should be obtained.

4.If a reading of 0 volt at one terminal and a reading of 108 V AC to 132 V AC at the other terminal is not obtained, the outlet is not properly grounded.

This condition should be corrected by a qualified electrician (per article 250 of the National Electrical Code).

5.If a reading of 0 volt at one terminal and a reading of 108 V AC to 132 V AC at the other terminal is obtained, then set the meter to the "OHMS/RX1" scale, place one probe at the GND Terminal and the other probe at the terminal which gave a reading of 0 volt.

A reading of less than 1 ohm should be obtained. If the reading is not obtained, the outlet is not adequately grounded. See qualified electrician.
