Polarity

Make sure that polar capacitors are connected

with the right polarity.

aluminum electrolytic

capacitors"

Reverse voltage

Voltages polarity classes should be prevented by

connecting a diode.

Upper category

temperature

Do not exceed the upper category temperatur.

7.2

"Maximum permissible

operating temperature"

Maintenance

Make periodic inspections of the capacitors.

Before the inspection, make sure that the power

supply is turned off and carefully discharge the

electricity of the capacitors.

Do not apply any mechanical stress to the

capacitor terminals.

Mounting

position of screw

terminal capacitors

Do not mount the capacitor with the terminals

(safety vent) upside down.

capacitors with screw

terminals"

Mounting of

single-ended

capacitors

The internal structure of single-ended capacitors

might be damaged if excessive force is applied to

the lead wires.

Avoid any compressive, tensile or flexural stress.

Do not move the capacitor after soldering to PC

board.

Do not pick up the PC board by the soldered

capacitor.

Do not insert the capacitor on the PC board with a

hole space different to the lead space specified.

Robustness of

terminals

The following maximum tightening torques must

not be exceeded when connecting screw

terminals:

M5: 2 Nm

M6: 2.5 Nm

Soldering

Do not exceed the specified time or temperature

limits during soldering.
