Terminal block power option
If the terminal block power option is selected, mainboard power is applied to the Helix platform
through a 4-pin terminal block connector (Mating part: Phoenix Contact #
1840382
or equivalent).
The system is operational from 8V~24V. The maximum rated current of the connector is 6A per pin.
Use a wire gauge that is rated for the operational current. Cables should be properly terminated with
wire ferrules. Do not use the terminal block with tinned wire ends or solid core wire. Always follow the
part number tightening torque and wire sizing specifications to prevent damage to connector
systems and PC. See below for connector pinout.
When using the remote switch connections with the terminal block option, mating power switch
cables should be a twisted-pair wire with floating shield to assure proper immunity to EMI/RFI. It is
recommended to keep wires at less than 3 meters in length. Switches should be momentary contact
type only.
