Wiring the Relay Contact

The EtherDevice Router has one set of relay outputs. This relay contact

uses one contacts of the terminal block on the EtherDevice Router’s top

panel. Refer to the next section for detailed instructions on how to

connect the wires to the terminal block connector, and how to attach the

terminal block connector to the terminal block receptor.

In this section, we illustrate the meaning of the contact used to connect

the relay contact.

FAULT:

The two

right contacts of the 4-pin terminal block

connector are used to detect user

-configured

events. The two wires attached to the

fault

contacts form an open circuit when a

user

-configured event is triggered. If a

user

-configured event does not occur, the fault

circuit remains closed.

Wiring the Redundant Power Inputs

The EtherDevice Router has two sets of power inputs—power input 1 and

power input 2. The top and front views of one of the terminal block

connectors are shown here.

STEP 1: Insert the negative/positive DC wires

into the V

-/V+ terminals, respectively.

STEP 2: To keep the DC wires from pulling loose,

use a small flat

-bl

ade screwdriver to tighten the

wire

-clamp screws on the front of the terminal

block connector.

STEP 3:

Insert the plastic terminal block

connector prongs into the terminal block

receptor, which is located on

the EtherDevice

Router’s top panel.
