The following procedure describes how to connect a PSU to DC power. Repeat this procedure to connect each PSU.

You need the following equipment to connect the FortiGate-7060E PSUs to DC power:

• An electrostatic discharge (ESD) preventive wrist strap with connection cord.
• One black 8 AWG stranded wire with attached UL approved ring terminal for 8/M4 studs with ext ring diameter < 9.8 mm.
• One red 8 AWG stranded wire with attached UL approved ring terminal for 8/M4 studs with ext ring diameter < 9.8 mm.
