* When the test input will not be used, connect it to 0V. If it is left disconnected, light transmission will stop.
When not using the light interference prevention connection, connect the main/sub switching input to 0 V. Leave
the light interference prevention cables disconnected after properly insulating them.
CAUTION
PNP output shielding is connected inside the SL-CHG to a 0 V line. When wiring
the device, do not connect the shield wire to a +24 V wire. Doing so will cause a
short between the power supply's +24 V wire and the 0 V wire, resulting in possible
damage to the power supply or equipment.

CAUTION
The NPN output shielding is connected inside the SL-CHG Series to a +24 V line.
When wiring the device, do not connect the shield wire to a 0 V wire. Doing so will
cause a short between the power supply's +24 V wire and the 0 V wire, resulting in
possible damage to the power supply or equipment.
WARNING
Synchronization cables must be shielded cable. Failure to use shielded cables may
result in significant harm to the machine operator, including serious injury or death.
Also, configure system wiring inside a metallic wiring box that has been connected
to the ground.
Total cable length should be 30 m (98.43 ft.) or less.
