Connecting Power

The RUGGEDCOM RS900G features a single, integrated high AC/DC or low DC power supply, which accept
dual power supply inputs for redundancy.
NOTE
Power sources can be connected to either power supply terminal block on the device.
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 only #16 gage copper wiring when connecting terminal blocks.
• Equipment must be installed according to applicable local wiring codes and standards.
The following sections describe how to connect power to the device:
• Section 2.2.1, "Connecting High AC/DC Power"
• Section 2.2.2, "Connecting Low DC Power"
Section 2.2.1

Connecting High AC/DC Power

To connect a high AC/DC power supply to the device, do the following:
CAUTION!
Electrical hazard – risk of damage to equipment. Do not connect AC power cables to terminals for DC
power. Damage to the power supply may occur.
CAUTION!
Electrical hazard – risk of damage to equipment. Before testing the dielectric strength (HIPOT) in the
field, remove the braided ground cable connected to the surge ground terminal and chassis ground.
This cable connects transient suppression circuitry to chassis ground and must be removed to avoid
damage to transient suppression circuitry during testing.
1. Connect the positive wire from the power source to the positive/live (+/L) terminal on the terminal block.
