2.4.2
Connecting Low DC Power
The RUGGEDCOM RMC8388 supports a single low DC power supply with dual power
supply inputs. The use of both power supply inputs is recommended to provide input
power redundancy.
To connect a low DC power supply to the device, do the following:
Electrical hazard – risk of damage to equipment
Do not connect AC power cables to terminals for low DC power. Damage to the
power supply may occur.
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 in
order to avoid damage to transient suppression circuitry during testing.

is used as the ground conductor for all surge and transient suppression circuitry
internal to the unit.
Connect the ground terminal on the power source to the chassis ground
terminal on the device.
