Grounding the Moxa EDS-P506A-4PoE
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 i
s intended to be mounted to a well-grounded
mounting surface such as a metal panel.
Wiring the Relay Contact
The EDS-P506A-4PoE has two sets of relay outputs—relay 1 and relay 2.
Each relay contact uses two contacts of the terminal block on the
EDS-P506A-4PoE’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.
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.
Wiring the Redundant Power Inputs
The EDS-P506A-4PoE has two sets of power inputs—power input 1 and
power input 2. The top two contacts and the bottom two contacts of the
6-pin terminal block connector on the EDS-P506A-4PoE’s top panel are
used for the two digital inputs. The top and front views of one of the
terminal block connectors are shown here.
STEP 1: Insert the
negative/positive DC wires into
t
he V-/V+ terminals, respectively.
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
the
EDS-P506A-4PoE’s top panel.
