9.3.4 DC Bus Electrolytic Capacitors
9.4 STORAGE
9.5 WARRANTY
1. Possible causes of damage: input
power supply in poor quality; high ambient
temperature; frequent load jumping; and
electrolytic aging.
2. Replacement determination criteria:
Whether there is liquid leakage; whether the
sage valve has projected; measure the static
capacitance; and measure the insulation
resistance.
For storage of the AC drive, pay attention
to the following:
1. Pack the AC drive with the original packing
box provided by Benshaw.
2. Do not expose the AC drive to moisture,
high temperature or outdoor direct sunlight
for an extended period.
Free warranty only applies to the AC drive itself.
Benshaw will provide a 24-month warranty
from date of manufacture for failure or damage
under normal use conditions. If the equipment
has been used for more than 24 months,
reasonable repair expenses will be charged.
A reasonable repair fee will be charged for
damages that occur within 24 months due
to the following causes:
1. Improper operation without following
the instructions.
2. Fire, flood or abnormal voltage.
3. Using the AC drive for non-recommended
functions.
4. Using the AC drive without following the
specifications.
5. Damage caused by force majeure, such as
natural disaster, earthquake or lightning strike.
The maintenance fee is charged according
to Benshaw’s uniform standard. If there is
an agreement, the agreement prevails.
For warranty details, refer to warranty terms
and conditions.
3. The electrolytic capacitor will deteriorate
after being stored for an extended period.
Thus, the AC drive must be turned on once
every 6 months, each time for at least 5 hours.
Be sure to increase the input voltage gradually
to rated value by using a voltage regulator.
3. Replacement of Electrolytic Capacitor:
Replacement of electrolytic capacitors by
users is not advised. Please contact the
factory for capacitor replacement.
