Verify that the remote power source is in the

position.
Locate the appropriate studs on the PEM front panel.
• The two right-handed studs (furthest from the GND) are the return (+48V DC) connection.
The cable
attached to these studs is typically red.
• The two left-handed studs (closest to GND) are the -48 V DC connection.
The cable attached to these studs
is typically black.
NOTE:
Power cables must be terminated only with a UL-listed 2-hole lug to accommodate 1/4-inch studs with
3/4-inch spacing.
Apply a coat of anti-oxidant paste to the connector studs, if required.
Replace the washers and nuts on the studs.
Route the terminated cables out toward the rack rail.
Cables will route down toward the floor. You can then route them as best suits your environment.
Secure the nuts with a nut driver or torque wrench (not to exceed 4 ft/lbs).
