Installing the Device
2.5Connecting Power
2.5 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
Note
The RUGGEDCOM RST916C is a dual input power supply system. Due to this
structure, induced voltages will be observed between the positive/live and chassis/
ground terminals, and between the negative/neutral and chassis/ground terminals.
CAUTION
Electrical hazard – risk of damage to the device
Do not connect more than one HI AC/DC power supply to the device. Connecting
more than one HI AC power supply could result in electrical damage to the device.
NOTICE
Electrical hazard – risk of power disruption
Due to power supply safety features, some AC/DC voltage will be coupled to
the redundant power terminals (between the positive/live and chassis/ground
terminals, and between the negative/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.
2.5.1 Connecting AC or DC Power
The device features dual power supply inputs to allow for redundant connections to
separate, independent power supplies. Each power supply terminal block provides
reverse polarity protection.
