Crimping Guidelines; Connecting A Fortigate-7040E Psu To Dc Power - Fortinet FortiGate-7000E Series System Manual

FortiGate-7040E chassis

Crimping guidelines

To connect the PSUs to data center power you should use 8 AWG or larger wires depending on the wire length and the
power requirements of your chassis. The ends of these wires must be fitted with UL approved ring terminals for 8/M4
studs with ext ring diameter < 9.8 mm. Use the following information to crimp and prepare these wires.
Follow these crimping guidelines:
Strip the insulation from cable. Be careful not to nick cable strands which may later result in stands breaking.
l
Cable end should be clean: wire brush or clean with emery cloth if necessary. Insert cable into connector until it
l
stops. The insertion length must approximate the stripped length of cable.
Insert connector in die and compress between the markings beginning near the tongue of the connector. Using the
l
wrong installing die may result in a defective connection.
After crimping, remove all sharp edges, flash or burrs.
