It is strongly advised that you label wiring to all devices in the system when
necessary.
Grounding Moxa EtherDevice Switch
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the
ground screw, on the side panel of EDS-726, 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
In this section, we explain the meaning of the two contacts used to connect the
alarm contact.
EDS-726 has two sets of relay output—relay 1 and relay 2. Each relay contact
consists of the two contacts of the terminal block on EDS-726’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.

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 will be
closed.
Wiring the Redundant Power Inputs
EDS-726 has two sets of power input—power input 1 and power input 2.The
top two contacts and the bottom two contacts of the 6-pin terminal block
connector on EDS’s top panel are used for EDS’s two digital inputs.

STEP 1
: Insert the
negative/positive DC wires into the
V-/V+ terminals.
STEP 2
: To keep the DC wires
from pulling loose, use a small
flat-blade 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 EDS-726’s top panel.
