prevention cable output
* When test input will not be used, connect it to 0 V. 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.
* For information about how to wire the light interference prevention cables when establishing a light inter-
ference prevention connection, see “3-6 Connection for Light Interference Prevention ( ➮page 3-5)”.
