7. Avoid incorrect wiring.
<Reed>
A 24 VDC auto switch with indicator light has polarity. The brown lead wire or terminal No.1 is (+), and
the blue lead wire or terminal No.2 is (
－
).
1) If connections are reversed, an auto switch will operate, however, the light emitting diode will not light
up.
Also, take note that a current greater than that specified will damage a light emitting diode and it will
no longer operate.
Applicable model: D-93, A93V
<Solid state>
1) If connections are reversed on a 2-wire type auto switch, the auto switch will not be damaged if
protected by a protection circuit, but the auto switch will always stay in an ON state. However, it is still
necessary to avoid reversed connections, since the auto switch could be damaged by a load short
circuit in this condition.
2) If connections are reversed (power supply line + and power supply line
－
) on a 3-wire type auto
switch, the auto switch will be protected by a protection circuit. However, if the power supply line (+) is
connected to the blue wire and the power supply line (
－
) is connected to the black wire, the auto
switch will be damaged.
8. When the lead wire sheath is stripped, confirm the stripping direction. The insulator may be
split or damaged depending on the direction. (D-M9

Operation Environment
1. Never use in an atmosphere with explosive gases.
The structure if auto switches is not intended to prevent explosion. This may lead to explosion hazard.
Please contact SMC concerting ATEX compliant products.
1. Do not use in an area where a magnetic field is generated.
Auto switches will malfunction or magnets inside rotary tables will become demagnetized. (Please
consult with SMC if a magnetic field resistant auto switch can be used.)
