Note When using a reed switch as an input contact for an AC Input Unit, the allowable
current of the switch must be 1 A or greater. The contacts will be fused due to
inrush current if reed switches with a lower current capacity are used.
A fuse placed in the output circuit will protect the output element, circuit board,
etc., in the event of a short circuit in the output circuit. Although some Units have
a built-in fuse, it is recommended that you connect an external fuse to each Out-
put Unit for extra safety and ease of maintenance.
