Power Cord

The AT-iMG646xx series gateways are designed to be deployed with an uninterruptible power supply (UPS). You can purchase a UPS from Allied Telesis (part number AT-iMG005G). Install the power supply according to the manufacturer’s instructions included in the package.

Allied Telesis provides a 15 ft. power cord (part number AT-RG013). Alternatively, you can make custom length power cord. The terminal adapters are supplied with the AT-iMG005G UPS and the gateways. For lengths up to 50 ft., use three pair twisted wire with a minimum 18 AWG. Figure 57 on page 90 provides a detailed wiring diagram.

Caution

To properly ground the unit, you MUST install a terminal block ground wire as described in this procedure. The materials needed for the terminal block ground wire are described in “Additional Supplies” on page 54.

To prepare and connect the power cord, perform the following procedure:

Warning

Ensure that the UPS is OFF before you perform this procedure.
