ATTENTION
This unit is a built-in type. When the unit is installed in another
piece of equipment, the equipment enclosing the unit must
comply with fire enclosure regulation IEC 60950/EN60950 (or
similar regulation).
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or
wiring your MOXA EtherDevice Switch.
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:
y
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
y
NOTE: Do not run signal or communications wiring and power wiring
through the same wire conduit. To avoid interference, wires with different
signal characteristics should be routed separately
y
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
y
Separate input wiring and output wiring
y
We advise that you label wiring to all devices in the system when
necessary.
Grounding MOXA EDS-516A
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 Relay Contact
EDS-516A has two sets of relay outputs—relay 1 and relay 2. Each Relay
Contact consists of the two contacts of the terminal block on EDS-516A’s top
panel. You can 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 will explain the meaning of the two contacts used to
connect the Relay Contact.
