| Interval | Action | |----------|--------| | Monthly | Visual inspection for discoloration or burning | | Quarterly | Torque check on all power terminals | | Biannually | Contact resistance test (<100 mΩ) | | Annually | Replace if used in high-cycle applications (>100,000 ops) | Pro tip: If your manual is missing, generic

Pro tip: If your manual is missing, generic maintenance guidelines for DIN rail relays are 80% applicable, but always defer to the original specs.
