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.
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.
