RITERIA
Bonitron Model 3534R Ride-Thru uses high quality aluminum electrolytic
capacitors and is designed for long life without maintenance. While a
typical inverter may require capacitor replacement after a certain time due
to the heavy ripple currents, the M3534R typically is in a standby mode
waiting for a power disturbance.
With typical operating conditions of 35ºC, caps running at 75% rated
voltage, and a duty cycle of one sag per month, Bonitron recommends
the capacitors be checked or replaced every 20 years.

LEANING
Cleaning cycle depends entirely upon the surrounding environment and
the quality of air inside cabinet.
Cleaning off dust, debris, or chemical build-up on high voltage bus bars or
other exposed components may be necessary. If cleaning is needed:
1.
Remove power and allow all voltages to drain.
2.
Check for residual voltages with meter.
3.
Clean affected areas with rag, brush, or denatured alcohol,
depending on the type of contamination.
4.
Once area is clean and dry, reapply power.
