The drive intermediate circuit employs several electrolytic capacitors. Their life span
is from 35,000
…
90,000 hours depending on drive loading and ambient temperature.
Capacitor life can be prolonged by lowering the ambient temperature.
It is not possible to predict a capacitor failure. Capacitor failure is usually followed by
a input power fuse failure or a fault trip. Contact YORK if capacitor failure is
suspected. Replacements for frame size R5 and R6 are available from YORK. Do
not use other than YORK specified spare parts.

A battery is only used in Assistant control panels that have the clock function
available and enabled. The battery keeps the clock operating in memory during
power interruptions.
The expected life for the battery is greater than ten years. To remove the battery, use
a coin to rotate the battery holder on the back of the control panel. Replace the
battery with type CR2032.
