SpectraLink 6300 MCU: Facility Preparation
Prepare Power for Shelves
The SpectraLink 6300 MCU requires a -48V DC power source. The - 48V connection is comprised of three wires: -48, +48 (neutral), and ground.
Polycom recommends that a licensed electrician install the -48V power source. It must be installed according to current National Electrical Code (NEC) or National Fire Protection Code standards, in accordance with all local and municipal electrical code recommendations.
Use of 14 AWG wire is recommended.
See Chapter 4, section Connect Power to Shelves for more information on power connections.
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.
Run Cables to Base Station Locations
The Base Station locations should be designated on the building floor plans provided to the field service engineer. Base Stations can be mounted easily on raised or acoustical ceiling tiles, or on the wall. Avoid locating Base Stations in high or hard-to-reach places, as this will hinder maintenance, testing, or repositioning.
Wire specifications
The customer’s wire contractor is responsible for adhering to all local codes for wiring.
