The Gateway Module DC power input is isolated from chassis (earth). One lead of the DC power
feed is normally earth referenced external to the Pearl Gateway, usually at the power source by
convention.
An input overcurrent protection device rated not more than 20 A, and with the appropriate
current interrupt capacity for the power source, must be incorporated into the non-earthed
conductor(s) of the DC supply.
