You should also pay attention to the following items:
•
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
in the same wire conduit. To avoid interference, wires with different
signal characteristics should be routed separately.
•
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 with similar electrical characteristics can be bundled
together.
•
Keep input wiring and output wiring separated.
•
It is strongly advised that you label wiring for all devices in the system
when necessary.
Grounding the 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 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
Both power inputs can be connected simultaneously to live DC power
sources. If one power source fails, the other live source acts as a backup,
and automatically supplies the EDS-210A with power.
The two 2-contact terminal block connectors on the EDS's top panel are
used for the EDS's two DC power inputs. Top and front view of the
terminal block connectors 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 EDS’s top panel.
ATTENTION
Before connecting the EDS-210A to the DC power inputs, make
sure the DC power source voltage is stable.
