Maintaining Safety with Electricity

Follow these guidelines when working on equipment powered by electricity.


Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001

Warning This equipment must be installed and maintained by service personnel as defined by AS/NZS 3260. Incorrectly connecting this equipment to a general-purpose outlet could be hazardous. The telecommunications lines must be disconnected 1) before unplugging the main power connector or 2) while the housing is open, or both. Statement 1043

General Safety Practices

Follow these guidelines to ensure personal safety and protect the equipment:

Keep the chassis area clear and dust-free during and after installation.

Put the removed chassis cover in a safe place.

Keep tools away from walk areas where you and others could fall over them.

Do not wear loose clothing that could get caught in the chassis.

Wear safety glasses if you are working under any conditions that might be hazardous to your eyes.

Safety Tips

Use these tips as safety guidelines when installing or working around this equipment:

Locate the emergency power-off switch for the room in which you are working. Then, if an electrical accident occurs, you can act quickly to turn off the power.

Disconnect all power before installing or removing a chassis.

Do not work alone if potentially hazardous conditions exist.

Never assume that power is disconnected from a circuit. Always check.

Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds.

If an electrical accident occurs, proceed as follows:

Use caution; do not become a victim yourself.

Turn off power to the system.

If possible, send another person to get medical aid. Otherwise, assess the condition of the victim and then call for help.

Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD occurs when electronic components are improperly handled; it can result in complete or intermittent failures.

Always follow ESD-prevention procedures when removing and replacing components.

Ensure that the chassis is electrically connected to earth ground.

Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact.

Connect the clip to the ESD-strap connection jack (to the left of the power switch on the back of the chassis) or to an unpainted chassis frame surface.


Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohm (Mohm).

Before You Begin

Ensure that you meet the following conditions when you mount the chassis onto a wall:

The LEDs on the front panel face upward and are easily visible, because you will use the LEDs as status and problem indicators.

The back panel faces downward, to reduce strain on the cable connections.

The power supply rests on a horizontal surface such as the floor or a table. If the power supply is not supported, it can place strain on the power supply cable and cause it to disconnect from the connector on the back panel of the chassis.

Procedure


Step 1 Secure two screws 5 7/16 in (13.81 cm) apart into a wall and 5/32 in (0.40 cm) out from the wall.

Step 2 Hang the chassis on the screws as shown in Figure 3-3.

Step 3 Place the power supply on a horizontal surface.


Caution If you are mounting the voice gateway on drywall, use hollow-wall anchors (1/8 inch with 5/16-inch drill bit, or M3 with 8-mm drill bit) to secure the screws. If the screws are not properly anchored, the strain of the network cable connections could pull the voice gateway from the wall. Use two wall anchors with washers. Wall anchors and washers must be size number 10.


Setting the Chassis on a Desktop

You can place the voice gateway chassis on a desktop or shelf.


Caution Do not place anything on top of the chassis that weighs more than 10 lb (4.5 kg). Excessive weight on top can damage the chassis.

Procedure


Step 1 Place the four rubber feet (from the accessory kit) in the four indentations on the underside of the chassis. This helps provide proper airflow through and around the chassis.

Step 2 Place the chassis onto a smooth, flat surface.


Installing the Ground Connection

You must connect the chassis to a reliable earth ground; the ground wire must be installed in accordance with local electrical safety standards.

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.


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 Use copper conductors only. Statement 1025

Before You Begin

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 chassis and the ground of a power tap, and between the chassis and the ground of a junction box. A good ground connection should read between 0.0 and 0.5 Ohm.


Procedure


Step 1 Strip one end of the ground wire to the length required for the ring terminal.

Step 2 Crimp the ground wire to the ground lug or ring terminal, using a crimp tool of the appropriate size. (See Figure 3-4.)

Figure 3-4 Crimping a Ground Lug onto the Ground Wire

Step 3 Attach the ring terminal to the chassis as shown in Figure 3-5. For a ring terminal, use one of the screws provided. Use a number 2 Phillips screwdriver to tighten the screws to a torque of 8 to 10 in-lb (0.9 to 1.1 N-m).

Step 4 Connect the other end of the ground wire to a grounding point at your site.

Warnings


Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001

Warning Take care when connecting units to the supply circuit so that wiring is not overloaded. Statement 1018

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 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

Connecting Input Power to the Chassis

Procedure

Step 2 Connect the DB-9 end of the RJ-45-to-DB-9 serial cable to the to the COM port on your laptop or PC.


Note Some laptops and personal computers do not have DB-9 serial port connectors and may require a USB to serial port adapter.


Step 3 To communicate with the voice gateway, begin a terminal emulator application.


Connecting an FXS Line

Use a standard straight-through RJ-11 modular telephone cable to connect a Foreign Exchange Service (FXS) port to a telephone or fax machine.


Warning This equipment contains a ring signal generator (ringer), which is a source of hazardous voltage. Do not touch the RJ-11 (phone) port wires (conductors), the conductors of a cable connected to the RJ-11 port, or the associated circuit-board when the ringer is active. The ringer is activated by an incoming call.

Warning For connections outside the building where the equipment is installed, the following ports must be connected through an approved network termination unit with integral circuit protection: FXS.

Procedure


Step 1 Connect one end of the straight-through RJ-11 cable to the FXS port. Figure 3-8 shows an FXS line connection.
