AXP1440-C07 Shelf Installation
5.7 DC Power Cable
Power is introduced to the shelf through redundant DC PEMs. The recommended power
cable is an 4 AWG gauge that meets the specifications for this shelf. There are four lugs for
each PEM. Two are straight and the other two are custom offset lugs. The end that
connects to the external DC power source should be equipped with an 8mm terminal.
NOTICE
Always check with your local building authorities for wire sizing requirements for
your environment.
The installation must comply with the 1993 National Electric Code (NEC) and other
applicable codes.
The DC power inputs must only be attached to approved Telephone Network
Voltage (TNV) or SELV (Safety Extra Low Voltage) branch circuits. Branch circuits
must comply with all requirements called for in these safety standards: IEC 60950,
EN 60950, CAN/CSA-C22.2 No. 60950. Attaching inputs to non-TNV/SELV approved
power sources will cause the system to fail compliance with safety regulations.
The ground wire must be connected to a reliable earth ground connection to comply
with Class 1 Equipment requirements.
Multiple power sources are present.
Service only by qualified service personnel.
