DC Power Disconnection Warning for the JCS 1200 Platform
The JCS 1200 platform requires a DC wire rating of 4 AWG (circular mil area of
33100-52600) and of 90° C.
Flexible DC wiring is recommended to allow for minimum bend radius.
The supply wiring to the power connectors must be terminated in UL-recognized
insulated ring terminals, sized for an M6 stud, 4 AWG wire (circular mil area of
33100-52600), and a wire insulation diameter of 12.8 to 13.1 mm. An example
of this type of ring terminal is Amp Plasti-Grip type 520431 using Tyco Electronics
Hydraulic Crimping Tool part number 14907491.
For NEBS compliance, the grounding cable must use copper conductors with a
size minimum of 6 AWG (circular mil area of 2080033100) and must be
terminated in a UL-recognized two-hole lug sized for an M6 stud. An example
of this type of two-hole lug is the Thomas and Betts part number 54205 using
the Thomas and Betts crimping tool model TBM-25S.
