Connecting Power

The RUGGEDCOM RX1501 supports a single high AC, high DC or low DC power module.
Power modules can be equipped with either a screw-type or pluggable terminal block. The screw-type terminal
block is installed using Phillips screws and compression plates, allowing either bare wire connections or crimped
terminal lugs. Use #6 size ring lugs for secure, reliable connections under severe shock or vibration.
For information about installing or removing a power module, refer to
