Connecting Power
The RUGGEDCOM RS910W supports power input from a single high AC/DC or low DC power supply.
IMPORTANT!
• 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.
• All line-to-ground transient energy is shunted to the Surge Ground terminal. In cases where users
require the inputs to be isolated from ground, remove the ground braid between Surge and Chassis
Ground. Note that all line-to-ground transient protection circuitry will be disabled.
