Wiring Requirements
WARNING
Safety First
Turn the power off before disconnecting modules or wires. The
correct power supply voltage is listed on the product label. Check
the voltage of your power source to make sure that you are using
the correct voltage. Do NOT use a voltage greater than what is
specified on the product label
Calculate the maximum possible current in each power wire and
common wire. Observe all electrical codes dictating the
maximum current allowable for each wire size. If the current goes
above the maximum ratings, the wiring could overheat, causing
serious damage to your equipment.
You should also pay attention to the following points:
•
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 that shares similar electrical characteristics can be
bundled together.
•
Keep input wiring and output wiring separated.
•
It is strongly advised that you label wiring to all devices in the system
when necessary.
Grounding the 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
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 views of the
terminal block connectors are shown here.
