< Example of surge protector installation >
An example of installing the surge protector in the machine control panel is shown below.
A short-circuit fault will occur in the surge protector if a surge exceeding the tolerance is applied. Thus, install a circuit
protector in the stage before the surge protector. Note that almost no current flows to the surge protector during normal
use, so a circuit protector installed as the circuit protection for another device can be used for the surge protector.
Installing the surge absorber
1. The wires from the surge protector should be connected without extensions.
2. If the surge protector cannot be installed just with the enclosed wires, keep the wiring
length of A and B to 2m or less. If the wires are long, the surge protector's performance may
drop and inhibit protection of the devices in the panel.
3. Surge protector to be selected varies depending on input power voltage.
