Getting Started with Your Fiber Guardian
Fiber Guardian 47
Connecting the Power and the Network Cables
To connect the power to DC power supplies:
1. Ensure all power is off or disconnected at the source.
Note: A certified over-current protection of 5 A must be installed at the power
secondary distribution.
2. Ensure that the unit is grounded properly. For more information,
see Grounding Your Unit on page 28.
3. Crimp each power lead (minimum 14 AWG) with a UL-listed pressure
terminal connector (ring type). The connector must be suitable for 14
AWG wires.
4. Pair the power leads with the appropriate power terminal (located at
the back of the unit), respecting the polarity as indicated just below the
terminal block.
5. Tighten the screws to attach the power leads to the unit.
6. Turn on the disconnect devices that are connected to the unit.
As soon as the initialization sequence is complete (power LED is blinking
green), you are ready to turn on the unit (see Turning On or Off the Unit on
page 48).
