Maintenance Schedule

Maintenance intervals depend on the frequency mode.

  • For Low Frequency mode (the yearly average number of contactor cycles is less than 15 cycles/hour), perform maintenance every 12 months.

  • For High Frequency mode (the yearly average number of contactor cycles is greater than 15 cycles/hour or 136,986 cycles/year), perform maintenance at intervals that are 1/10th of the device estimated lifetime.

The device estimated lifetime (years) = B10d (=1,369,863) / yearly average number of contactor cycles
