Connecting the Power Cord
The AT-iMG646MOD gateway is designed to be deployed with an uninterrupted power supply (UPS). You
can purchase a UPS from Allied Telesis (part number AT-iMG005G/AT-iMG006G). Install the power supply
according to the manufacturer’s instructions included in the package.
Allied Telesis provides a 15 ft. power cable (part number AT-iMG646MOD-C01). Alternatively, you can
make custom length power cables. The power connectors (6-pin and 7-pin terminal blocks) are supplied with
the AT-iMG005G/AT-iMG006G) UPS and the gateways. For lengths up to 50 ft., use three pair twisted wire
with a minimum 18 AWG. Figure 27 on page 37 provides a detailed wiring diagram.
To connect the power cord, perform the following procedure:
1. Remove the grommet from the power cord entrance, cut a 1/4” “X” in it, and put it back in place.
2. Slip the power cord through the grommet.
3. Connect the wires in the power cord to the DC terminal block in the accessory kit (the wiring diagram is
shown in Appendix A) at 4.5 in-lbs. Or, use the Allied Telesis power cord, model AT-iMG646MOD-C01
(not provided).
4. Plug the terminal block into the DC power socket, as shown in Figure 7.
5. If not using the console cable, seal the grommet
6. Tie-wrap the power cable, using one of the secure posts or the lower channel.
