Overview
The devices can be powered by using the same DC source used to power other
devices. A DC voltage range of 12 to 48 V
DC
must be applied between the V1+
terminal and the V1- terminal (PW1), see the following illustrations. The chassis
ground screw terminal should be tied to the panel or chassis ground. A redundant
power configuration is supported through a secondary power supply unit to reduce
network down time as a result of power loss.
EKI-6333AC-4GP support 12 to 48 V
DC
. Dual power inputs are supported and allow
you to connect a backup power source.
