Figure 9 Attaching the Chassis to a Wall
Grounding the Chassis
Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024
Warning AC connected units must have a permanent ground connection in addition to the power cable ground wire. NEBS-compliant grounding satisfies this requirement. Statement 248
Warning Use copper conductors only. Statement 1025
You must connect the chassis to a reliable earth ground; the ground wire must be installed in accordance with local electrical safety standards.
•For NEBS-compliant grounding, use size AWG 6 (13 mm2) wire and the ground lug provided in the accessory kit.
•For NEC-compliant grounding, use size AWG 14 (2 mm2) or larger wire and an appropriate user-supplied ring terminal.
•For EN/IEC 60950-compliant grounding, use size AWG 18 (1 mm2) or larger wire and an appropriate user-supplied ring terminal.
To connect the chassis to a reliable earth ground, perform the following steps:
Step 1 Locate a suitable ground.
Tip Using a multimeter, measure the resistance between various possible ground locations, such as between the ground of a junction box (outlet) and the ground of a power tap, between the ground of a junction box and a metal water pipe, between the Cisco IAD chassis and the ground of a power tap, and between the Cisco IAD chassis and the ground of a junction box. A good ground connection should read between 0.0 and 0.5 ohms.
Step 2 Strip one end of the ground wire to the length required for the ground lug or terminal.
•For the NEBS ground lug—approximately 0.75 in. (20 mm)
•For user-provided ring terminal—as required
Step 3 Crimp the ground wire to the ground lug or ring terminal, using a crimp tool of the appropriate size.
Step 4 Attach the ground lug or ring terminal to the chassis as shown in Figure 10 or Figure 11. For the ground lug, use the two screws with captive locking washers provided. For a ring terminal, use one of the screws provided. Use a number 2 Phillips screwdriver, and tighten the screws to a torque of 8 to 10 in-lb (0.9 to 1.1 N-m).
Step 5 Connect the other end of the ground wire to a grounding point at your site.

6 Connecting Cables
Warning Do not work on the system, or connect or disconnect cables during periods of lightning activity. Statement 1001
Warning Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the unit first. Statement 1026
Warning Read the installation instructions before connecting the system to the power source. Statement 1004
Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that the protective device is rated not greater than:
120 VAC, 15A (240 VAC, 10A international) Statement 1005
Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021
Warning To prevent accidental discharge in the event of a power line cross, route on-premise wiring away from power cables and off-premise wiring, or use a grounded shield to separate the on-premise wiring from the power cables and off-premise wiring. A power line cross is an event, such as a lightning strike, that causes a power surge. Off-premise wiring is designed to withstand power line crosses. On-premise wiring is protected from power line crosses by a device that provides overcurrent and overvoltage protection. Nevertheless, if the on-premise wiring is in close proximity to, or not shielded from, the off-premise wiring or power cables during a lightning strike or power surge, the on-premise wiring can carry a dangerous discharge to the attached interface, equipment, and nearby personnel. Statement 338
Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement 1003
Warning This equipment has been designed for connection to TN and IT power systems. Statement 1007
Connecting LAN and Power Cables
Caution The Cisco VG224 Voice Gateway provides inputs for both AC and DC power. Design your installation to use only one type of power. Do not use AC and DC power at the same time. If you do, the unit stops operating, and you must reboot it with only a single power source.
