Connecting Power
The RUGGEDCOM M2200 supports a single or dual redundant AC and/or DC power supplies.
The RUGGEDCOM M2200 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.
CAUTION!
Electrical hazard – risk of damage to the device. Disconnect the device from the power supply if power
input is above or below the specified input range. For more information, refer to Section 5.1, “Power
Supply Specifications” .
NOTE
• For maximum redundancy in a dual power supply configuration, use two independent 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.
• For 125/250 VDC rated equipment, an appropriately rated DC 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.
• Equipment must be installed according to applicable local wiring codes and standards.
