KEYENCE Visual KV Series - Manual (Page 3)

Note to User
When using the Visual KV Series in the following conditions or environments, be
sure to use the Visual KV Series with sufficient margin regarding the rating and
functions, take appropriate safety precautions such as fail-safe, and contact our
sales personnel if any questions arise.
• Use in conditions or environments not described in this manual
• Use for nuclear power control, railway facilities, air service facilities, vehicles,
combustion devices, medical equipment, amusement machines, safety equip-
ment, etc.
• Use for applications where large effects are predicted to be given on human lives
and properties and safety is especially requested.
Restriction on Acquiring the CE Marking
■ Restriction to be compatible with EMC directives
•
When using a relay output type unit (whose model name ends with "R"), connect
spark killers having the appropriate withstand voltage against the load to the
output terminals in parallel to contacts (because the unit discharges when a relay
contact becomes open and noise is generated). In our experiments, we use the
following models of spark killers.

The following 1-turn ferrite core is added to the AC power input circuit of the KV-
40AR/T, the KV-24AR/T and to the DC power input circuit of the KV-40DR/T.

Note: The contents above do not by themselves ensure that the entire machine
manufactured in accordance with the above contents is compatible with EMC
directives.
You must judge by yourself whether or not the entire machine is compatible with
EMC directives because compatibility may change depending on the component
configuration, wiring and location inside of the machine.
■ Restriction on compatibility with low-voltage directives (IEC-1010-1)
•
Use insulated type crimp-style terminals.
• For wiring materials, use lead wires whose sheath is 0.4 mm or more.
• The Visual KV Series is allowed to be installed in a vertical position only.
(Spacers for expansion units are not available.)
• Be sure to use the Visual KV Series inside the control panel.
