Figure 4 Terminal Block Mating Connectors Connected to Router Chassis
Connect to AC Power
This section describes how to make two the following types of AC power connections to the router:

Single-phase AC

Three-phase AC
Note: The AC power connection mating connector shipped with the router is a 5-way screw terminal printed circuit board
plug connector manufactured by Phoenix Contact (part number 1913604).
To connect the router to AC power, follow these steps:
Note: The router will power on as soon as it is connected to an AC power source. You are not required to press a power
button to power on the router.
Caution: When connecting the router AC power connector, always connect the router end of the cable first. When
removing the AC power connector, always disconnect the router end of the cable last.
1. Turn off power to the AC power source at the designated circuits.
2. Use a wire-stripping tool to strip each of the wires from the AC-input power source. Expose the wire to the
appropriate length for the terminal block, about 0.25 inches.
3. Insert the wires into the AC power connector terminals described in Figure 1 on page 48 and Table 1 on page 48 .
Insert wires that correspond to your installation (three-phase or single-phase), as shown in Figure 5 on page 52 .
