5.2.4 Lightning Surge Protection Countermeasure
Generally, the lightning surge intrudes into the control power supply of device from the power supply line, and the surge
may damage the control power supply and the internal circuit.
For protection from the lightning surge, MITSUBUSHI NC unit has the surge absorber for the control power supply of the
NC control section and the NC drive section.
However, when there is a device which is not applied with the countermeasure as illustrated below, the lightning surge
may intrude through the signal line of the device which is not applied with the countermeasure and may damage the NC
device.
(1) Protection countermeasure method
Add the surge absorber to the power supply lines as illustrated below for the power supply device, etc., which are
separately prepared.
The following two items are needed to protect the whole from surge.
- Surge absorber installation
- Circuit protector installation
(2) Product example of surge absorber
Case of OKAYA ELECTRIC INDUSTRIES surge absorber
(Note)
Refer to "EMC Installation Guidelines: EMC Countermeasure Parts: Surge Absorber" for the outline, etc.
Refer to the manufacturer catalog for detailed characteristics, outline and connection methods of the
surge absorber.
