Appendix 4-6-4 Surge protector
Insert a surge protector in the power input section to prevent damage to the control panel or power supply unit,
etc. caused by the surge (lightning or sparks, etc.) applied on the AC power line.
Use a surge protector that satisfies the following electrical specifications.
< Surge protector for 200V >
200V R•A•V-BYZ Series (for protection between lines)
(Note) Refer to the manufacturer's catalog for details on the surge protector's characteristics and
specifications.
200V R•A•V-BXZ Series (for protection between line and earth)
(Note) Refer to the manufacturer's catalog for details on the surge protector's characteristics and
specifications.
