Power Supply Installation

2.7.1

Overview

Warning! Power down and disconnect the power cord before servicing or wiring
the fieldbus gateway.
Caution! Do not disconnect modules or cabling unless the power is first switched
off.
The device only supports the voltage outlined in the type plate. Do not
use any other power components except those specifically designated
for the fieldbus gateway device.
Caution! Disconnect the power cord before installation or cable wiring.
The fieldbus gateways can be powered by using the same DC source used to power
other devices. A DC voltage range of 12 to 48 V
terminal and the N1 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 by a secondary power supply unit to reduce
network downtime as a result of power loss.
EKI-1242NR Series support 12 to 48 V
allow you to connect a backup power source.
