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.
These devices must be supplied by a SELV source as defined in
the Low Voltage Directive 2014/35/EU and 2014/30/EU.
WARNING
Safety
First!
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
