Wiring Example
This example shows wiring for conforming to undervoltage reference.
* 1. The main circuit is separated from the terminal cover for safety reasons.
* 2. The contact output circuit is separated from the main circuit and the control circuit by reinforced insulation.
It can be connected to extra-low voltage circuits or circuits that are 250 VAC 1 A, 30 VDC 1 A or less.
* 3. The control circuit is an extra-low voltage circuit and separated from the main circuit and the contact output circuit by reinforced insulation. Always
connect it to extra-low voltage circuits.
