WARNING
This switch is not explosion-proof.
If an explosion-proof specification is required, use the VCX-5✽✽✽ series.
CAUTION
Until wiring, do not remove the cover and the plug of the limit switch in order
to prevent dust or liquid from entering the limit switch.
Failure to prevent this might result in malfunction or contact failure.
As soon as wiring is completed, replace the cover of the limit switch to
prevent dust and/or liquid from entering the switch housing. Failure to prevent
this might result in malfunction or contact failure.
Before using the limit switch for the first time, protect it using a dust-proof,
water-proof sheet to prevent cement and/or paint from adhering to the switch,
as this may cause lever malfunction.
Do not leave the limit switch in an atmosphere containing gases (H2S, SOx
etc.) that may adversely affect the contact and/or other materials. Failure to
observe this instruction may cause contact failure.
Do not allow limit switch to come into contact with solvent (benzene,
kerosene, alcohol, etc.) that may adversely affect it. Failure to observe this
instruction may result in malfunction and/or insulation failure.
Do not step on the limit switch, place heavy objects on it or hit it with a hard
object. Never apply to the switch lever a force five times larger than its
operation force (OF). Failure to observe this instruction may result in
malfunction.
When using sealing or other locking agent on the conduit, make sure that it
does not generate gasses which may cause contact failure.
The limit switch must be mounted using heat insulating materials, shielding
plates, etc., so that its temperature will not exceed the working temperature
range as a result of radiant heat or heat transfer.
If the limit switch is subjected to continuous vibration or impact, be sure to
take the necessary measures to isolate it from vibration.
