Please read and follow these guidelines:

y Use separate paths to route wiring for power and devices. If power wiring

and device wiring paths must cross, make sure the wires are perpendicular

at the intersection point.

NOTE: Do not run signal or communications wiring and power wiring

through the same wire conduit. To avoid interference, wires with different

signal characteristics should be routed separately.

y You can use the type of signal transmitted through a wire to determine

which wires should be kept separate. The rule of thumb is that wiring

sharing similar electrical characteristics can be bundled together

y You should separate input wiring from output wiring

y We advise that you label the wiring to all devices in the system.

Grounding the Moxa EDS-G509

Grounding and wire routing help limit the effects of noise due to

electromagnetic interference (EMI). Run the ground connection from the

ground screw to the grounding surface prior to connecting devices.

ATTENTION

This product is intended to be mounted to a well-grounded

mounting surface such as a metal panel.

Wiring the Relay Contact

The EDS-G509 has two sets of relay outputs—relay 1 and relay 2. Each relay

contact uses two contacts of the terminal block on the EDS-G509’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 two contacts used to connect

the relay contact.

RELAY1

RELAY2

FAULT:

The two sets of relay contacts of the 6-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.
