4.5. Connect Power to Shelves
SpectraLink recommends that a licensed electrician install the –48V DC power supply
and connect power to the shelves.
When connecting the -48 V DC system to power, note the following
precautions:
A 30 amp circuit breaker must be present on the non-grounded DC circuit
conductor, and the installer must ensure that means are provided for
connection of the equipment to the DC source by permanent wiring
methods, and no disconnecting device is located in the grounded DC circuit
conductor between the point of connection to the supply and the point of
connection to the grounding electrode and equipment grounding
conductors.
The DC input to the power supply is polarity sensitive. Incorrect hookup
will prevent normal operation of the system and may cause damage.
Double check polarities before making any connections. Verify that the DC
power switch on each shelf is OFF.
Run Conduit To Shelf
The shelves have two possible points of entry for conduit: on the side, used for wall
mounted shelves, or in the rear, used for rack mounted shelves.
Select the point of entry (side or rear) for this installation and unplug the correct opening
on each shelf to be installed.
For each shelf:
1. Attach the conduit entry hardware (condulet) to the conduit.
2. Pull the conduit through the hole.
Connect Wire to Terminals
Connect the wire to the terminal strip and grounding stud, as shown in the following
illustration. Position the wires to be flat against the back of the shelf.
