2. Wire separately from power lines of high voltage lines, avoiding parallel wiring of wiring in
the same conduit with these lines.
If an inrush current is generated, the noise may cause the auto switch to malfunction.
3. Be certain to connect the load before power is applied.
<2-wire type>
If the power is turned ON when an auto switch is not connected to a load, the auto switch will be
instantly damaged because of excess current (short circuit).
It is the same as when the 2-wire brown lead wire (+, output) is directly connected to the (+) power
supply terminal.
4. Carry out the wiring work after shutting down the power.
If the wiring work is performed with the power turned ON, this may cause electric shock, malfunction, or
damage to the auto switch.
5. Avoid repeatedly bending or stretching lead wires.
Broken lead wires will result from repeatedly applying bending stress or stretching force to the read
wires.
Stress and tensile force applied to the connection between the lead wire and auto switch increases the
possibility of disconnection.
6. Do not allow short-circuit of loads.
<Solid state>
PNP output type auto switches do not have built-in short circuit protection circuits.
Carefully handle as the auto switch may be damage.
Take special care to avoid reverse wiring with the brown power supply line and the black output line on
3-wire type auto switches.
7. Avoid incorrect wiring.
<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
