1. Shut down the equipment by removing the power supply.
NOTE
The
F series
is fitted with electrolytic filter capacitors. Assuming that there
is an average temperature of 35°C with 20 hours of operation per day, the
average life of the electrolytic capacitors is about 5-6 years.
The
K series
is fitted with maintenance-free metallized polypropylene
capacitors. Assuming an average temperature of 35°C and a working time of
20 hours a day, the average life of these capacitors is about 100,000 hours.
In general capacitors (rated voltage = 900Vdc) may be stored for three years
at temperatures up to 50°C without any reduction of their reliability.
After a prolonged storage period, the leakage current value can exceed the
rated value and a re-anodizing procedure is required prior to its use. It can be
performed by applying the rated voltage, at room temperature, for one hour.
In any case it is advisable to use a maximum charging current value of 5mA
or equal to two times the typical value specified for each series.
The CAPACITORS FORMATTING procedure is explained below:
Electrolytic capacitors retain their original features only if they are powered
up within 1 year from the date of delivery. Yearly reformatting guarantees
the immediate availability of the drive stored and, therefore, its prompt
replacement in case of a possible drive failure.
The use of an drive with unformatted capacitors can cause the capacitors
and drive failure. The reformatting methods and the following instructions
assume that the drive has been stored in a clean environment with no
humidity. To determine the age of the drive, see the test date on the label of
the drive as shown below.
