Grounding the WDR-3124A
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 Redundant Power Inputs
The top two pairs of contacts of the 10-contact terminal block connector
on the WDR-3124A’s top panel are used for the WDR-3124A’s two DC
inputs. Top and front views of the terminal block connector are shown
here.
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 the WDR-3124A’s
t
op panel.
ATTENTION
Before connecting the
WDR-3124A
to the DC power inputs, make
sure that the DC power source voltage is stable.
Wiring the Relay Contact
The WDR-3124A has one relay output, which consists of the two contacts
of the terminal block on the WDR-3124A’s top panel. Refer to the
Specification section for detailed electrical requirement. The relay
contacts are used to indicate user-configured events. The two wires
attached to the relay contacts form an open circuit when a
user-configured event is triggered. If a user-configured event does not
occur, the relay circuit will be closed.
Wiring the Digital Inputs
The WDR-3124A has two sets of digital inputs—DI1 and DI2. Each DI
comprises two contacts of the 6-pin terminal block connector on the
WDR-3124A’s top panel. Refer to the Specification section for detailed
information on isolated digital input definition.
