RuggedCom® RuggedSwitch® 20 RSG2300 Installation Guide Rev 110
• RSG2300P will always have a 48VDC power supply in position PS2.
• 110/230VAC rated equipment: A 250VAC appropriately rated circuit breaker must
be installed.
• 125/250VDC rated equipment: A 300VDC appropriately rated circuit breaker must
be installed.
• A circuit breaker is not required for 12-24 or 48VDC rated power supplies.
• Separate circuit breakers must be installed and separately identified.
• Equipment must be installed according to the applicable country wiring codes.
3.2.4. Dielectric Strength (HIPOT) Testing
For dielectric strength (HIPOT) testing in the field, users must remove the metal jumper located
across terminals 2, 4, and 6 of the power supply terminal block. This metal jumper connects
transient suppression circuitry to chassis ground and must be removed in order to avoid damage
to transient suppression circuitry during HIPOT testing. The figure below shows the proper HIPOT
test connections and should be followed to avoid damage to the device.

3.2.5. Failsafe Alarm Relay Wiring and Specifications
The “Failsafe” output relay is provided to signal critical error conditions that may occur on RS2000
series products. The contacts are energized upon power-up of the unit and remain energized
unless a critical error occurs. The proper relay connections are shown in the figure below. Control
of this output is user selectable and can be programmed via the Rugged Operating System (ROS).
One common application for this output is to signal an alarm if a power failure or removal of control
power occurs.
