3.3.2.1 DC Power Cable
Power is introduced to the shelf via 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.
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.
