Connecting Power

The RUGGEDCOM RST2228 supports dual redundant AC and/or DC power supplies that can be installed in any
combination.
The RUGGEDCOM RST2228 can be equipped with either a screw-type or pluggable terminal block, which provides
power to both power supplies. 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.
