Capacitors
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 factory if capacitor failure is suspected. Replace-
ments for frame size R5 and R6 are available from the factory. Do not use other than factory
specified spare parts.
Control Panel
Cleaning
Use a soft damp cloth to clean the control panel. Avoid harsh cleaners which could scratch the
display window.
Battery
A battery is only used in control panels that have the clock function available and enabled.
The battery keeps the clock operating in memory during power interruptions. 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.
