IMG 1004 - Connecting AC Power

Overview

The IMG 1004 supports an AC power option to support domestic and international customers. The AC power module is located in the rear of the chassis. Internally the output of the AC power module connects to a power supply board mounted to the inside of the IMG 1004. This board converts an AC voltage to a DC voltage and then feeds the DC voltage to the main board through a 6 wire cable assembly.

Warnings/Cautions

Ensure the AC power module switch is set to O (Off) prior to connecting the IMG 1004 to the AC power source.

Procedure

Complete the following steps to connect AC power to the chassis.

Toggle power module switch to 0 position (Off)
Plug AC cable into the receptacle on the AC power module
Insert other end into a grounded wall outlet, uninterruptible power supply (UPS), or surge protector.
Press switch on the AC power module to I (On).

AC Power Module

The AC power is provided through a standard three position male AC input power module that has an integrated fuse and power switch built in. This power module will allow for all variations of AC power outlets by simply using a standard power cable with a compatible outlet plug for your application. The figure below shows the AC Power Module.

Other Considerations

Uninterruptible Power Supply Option

If your site has frequent power interruptions, consider using an Uninterruptible Power Supply (UPS) for your IMG 1004. You can avoid downtime by running your system that receives its AC power from batteries during a power failure.

Surge Protection

It is advisable to install a surge protector between your call processing system and the power outlet. If a high voltage surge occurs on the power line, this device can protect your system by sending the overload to ground.
