Power

Three-input 240-A DC power supplies: Twelve 4-AWG (21.2 mm2), minimum 90°C wire, or as required by the local code

Four-input 240-A DC power supplies: Sixteen 4-AWG (21.2 mm2), minimum 90°C wire, or as required by the local code

Cable lug; dual hole, sized to fit 1/4-20 UNC terminal studs at 15.86-mm (0.625-in.) center line.

 

Warning: For field-wiring connections, use copper conductors only.

Caution: Power cables must not block access to router components or drape where people could trip on them.

Caution: You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and (–) to indicate their polarity. There is no standard color coding for DC power cables. The color coding used by the external DC power source at your site determines the color coding for the leads on the power cables that attach to the terminal studs on each power supply.

DC Power Lugs

The accessory box shipped with the router includes the cable lugs that attach to the terminal studs of each power supply. (The cable lug shown in Figure 1 is also used for the grounding the chassis.)

Caution: Before router installation begins, a licensed electrician must attach a cable lug to the power cables that you supply. A cable with an incorrectly attached lug can damage the router.
