Advanced FE/E1 Fiber Converters
FEM/FEM4 with 48 VDC Power Supply ( PS48 )
Proceed as above using a suitable DC supply cable. Verify that the DC-Mains
provide a 10Amp DC circuit breaker. Ensure that the polarity of the cable complies
with the polarity of the DC receptacle on the device as depicted above. If you use the
FibroLAN CBPS-48V cable (B151), insert all-way-in the D-type DC connector and
secure the D-Shell to the DC Inlet of the FEM/FEM4 device using the two captive
screws. Connect the cable 3 leads to the DC Power Outlet, ensuring that the -48V
blue lead is connected to the -48V of the DC Power Outlet, the red/brown OV lead to
the OV of the DC Power Outlet, and the ground lead (yellow/green) to the ground of
the DC Power Outlet. There is no ON/OFF switch on the device. When the power is
connected to the device, the device is ON. The POWER LED being illuminated will
indicate this.
NEVER OPEN THE DEVICE WHEN IT IS CONNECTED TO POWER LINES!
