2.6 Connecting Power
The RUGGEDCOM RSG2100 supports a single or dual redundant AC and/or DC power
supplies.
The RUGGEDCOM RSG2100 can be equipped with either a screw-type or pluggable
terminal block, which provides power to both power supplies . The screw-type ter-
minal 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, reli-
able connections under severe shock or vibration.
CAUTION
Electrical hazard – risk of power supply failure or damage to the device
Make sure power input to the device is within the specified input range. If power in-
put is too high, damage to the power supply may occur. If power input is too low,
damage to the device may occur. For information about the nominal input range for
the device, refer to "Power Supply Specifications (Page 31)".
Note
• For maximum redundancy in a dual power supply configuration, use two inde-
pendent power sources.
• Use minimum #16 gage copper wiring when connecting terminal blocks.
• For 100-240 VAC rated equipment, an appropriately rated AC circuit breaker
must be installed.
• A circuit breaker is not required for 12, 24 or 48 VDC rated power supplies.
• It is recommended to provide a separate circuit breaker for each power supply
module.
