IMG 1004 - AC Power Information (in On-line Help)
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.
1. Toggle power module switch to 0 position (Off)
2. Plug AC cable into the receptacle on the AC power module
3. Insert other end into a grounded wall outlet, uninterruptible power supply (UPS), or surge
protector.
4. 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.
