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