Connecting Power
The RUGGEDCOM RST916C features two input terminals that allow the device to be
powered by:
• Up to one independent AC and one independent DC power source
• Two independent DC power sources
NOTICE
Electrical hazard – risk of power disruption
Due to power supply safety features, some AC voltage will be coupled to the
redundant power terminals (between the positive/live and chassis/ground terminals,
and between the neutral and chassis/ground terminals). While the maximum
amount of current transfer is below the safety threshold, it may be enough to trip
some external Ground Fault Circuit Interrupter (GFCI) breakers. Before connecting
power, review the installation and make sure this condition can be supported.
Note
• For 110/230 VAC rated equipment, an appropriately rated AC circuit breaker
must be installed.
• For 125/250 VDC rated equipment, an appropriately rated DC circuit breaker
must be installed.
• Use minimum #16 gage copper wiring when connecting terminal blocks.
• Equipment must be installed according to applicable local wiring codes and
standards.
2.6.1
Connecting AC or DC Power
The device features dual power supply inputs to allow for redundant connections
to separate, independent DC power supplies. Each power supply terminal block
provides reverse polarity protection.
