To connect the PEMs in a power feed to DC power
1.
Attach the ESD wrist strap to your wrist and to an ESD socket or to a bare metal surface on the chassis or frame.
2.
Make sure that the PEMs and power cords are not energized.
3.
Remove the PEM terminal covers.
4.
Remove the first set of nuts and lock washers from the connectors on each PEM.
5.
Connect black -48V power wires from the DC power source to the connectors on the PEMs labeled - using
double-hole lugs. Install each double-hole lug vertically. Do not apply torque of more than 3.8 Nm (33.62 lbf.in).
6.
Connect red RTN power wires from your location’s RTN terminal to the connectors on the PEMs l using
double-hole lugs. Install each double-hole lug vertically. Do not apply torque of more than 3.8 Nm (33.62 lbf.in).
7.
Install previously removed nuts and washers to secure the connectors.
8.
Make sure the power wires are secured using tie wraps if required.

The FortiGate-5144C chassis includes a ground terminal on the rear the bottom of the FortiGate-5144C back panel.
The ground terminal provides two connectors to be used with a double-holed lug such as Thomas & Betts PN 54850BE.
This connector must be connected to a local ground connection.
You need the following equipment to connect the FortiGate-5144C chassis to ground:
l
An electrostatic discharge (ESD) preventive wrist strap with connection cord.
l
One green 8 AWG stranded wire with listed closed loop double-hole lug suitable for minimum 8 AWG copper wire,
such as Thomas & Betts PN 54850BE.
