Technical Notes (Operation Environment); Warranty - Mitsubishi Electric AE-SW Series Instruction Manual

 Operation environment
1. Standard operation environment
The standard operation environment is an environment
where all of the following conditions are met. Unless
otherwise specified, use the AE Series air circuit breaker
in the following environment.
① Standard ambient temperature
Use in the range of +40 °C max. and -5 °C min. However,
the average temperature over 24 hours must not exceed
+35 °C.
② Altitude: 2000 m (6600 feet) or less.
③ Environmental conditions
The air must be clean with the max. temperature of
+40 °C and the relative humidity of 85% or less, and
without condensation.
Do not use and store in an atmosphere with corrosive
gas, such as sulfide gas and ammonia gas.
(H S 0.01 ppm or less, SO 0.05 ppm or less, NH

④ Installation condition
Install the AE Series air circuit breaker in accordance
with the instructions on the catalog and the instruction
manual.
⑤ Guideline for replacement
Expected product life is 15 years in the standard
operation environment.
Time of replacement is highly influenced by the
operation environment. Refer to the inspection and
maintenance section of this instruction manual.

Warranty

If any faults or defects (hereinafter "Failure") found to be
the responsibility of Mitsubishi Electric occurs during use of
the product within the warranty period, the product shall be
repaired at no cost via the sales representative or Mitsubishi
Electric Sales office. However, if repairs are required on-
site at domestic or overseas locations, expenses to send an
engineer will be charged.
1. Warranty period
The warranty period of the product shall be for twelve
(12) months after the date of purchase or delivery to
the designated place. Note that after manufacture
and shipment from Mitsubishi Electric, the maximum
distribution period shall be six (6) months, and the
longest warranty period after manufacturing shall be
eighteen (18) months. The warranty period of the repaired
parts shall not exceed the warranty period of the original
product before repairs.
2. Warranty coverage
(1) The primary failure diagnosis should be performed
by users. However, if required by users, Mitsubishi
Electric or Mitsubishi Electric Sales office may be able
to perform the diagnosis. In that case, for damages
caused by any cause found to be the responsibility of
Mitsubishi Electric, the diagnosis will be performed at
no cost. For details, contact a distributor.
(2) The coverage shall be limited to ordinary use within
the usage state, usage methods, usage environment,
and other conditions which follow the instructions and
precautions given in the instruction manual, user's
manual, and caution labels on the product.
(3) Even within the warranty period, repair cost shall be
charged for the following cases.
[1] Failure occurring from inappropriate storage or
handling, carelessness or negligence by the user.
Failure caused by selection of hardware or software
design on the user side.
2. Special operation environment
When the product is used in a condition other than the
standard operation environment, its service life may be
shorter.
① Special operation environment
② Special ambient temperature
③ Special altitude
0.25 ppm or less)

In addition, the warranty applies only to the product
delivered. It does not apply to the damage that is caused by
the failure of the product.
3. The period to supply the spare parts after discontinuation
of production
Mitsubishi Electric shall supply spare parts for five years
after discontinuation of production.
After five years, Mitsubishi Electric shall supply spare
parts until the spare parts run out of stock.
Operation with high temperature and high humidity.
Operation in an environment where corrosive gas is
present.
When the ambient temperature exceeds +40 °C,
"uninterrupted current" is reduced.
When using the product at an altitude over 2000
m, heat dissipation becomes less. This leads to a
reduction of the operation voltage, current capacity,
and breaking capacity. The dielectric strength is also
lowered by the air pressure. Please contact us for
details.
[2] Failure caused by modifications, etc. to the product
by the user without any approvals from Mitsubishi
Electric.
[3] In case Mitsubishi Electric product is assembled
into a user's device, failure that could have been
avoided if functions or structures, judged as
necessary in the legal safety measures the user's
device is subject to or as necessary by industry
standards, had been provided.
[4] Failure that could have been avoided if the
maintenance described in the user's manual has
been performed.
[5] Failure caused by external irresistible forces such
as fires or abnormal voltages, and failure caused
by natural disasters such as earthquakes, lightning,
wind and water damages.
[6] Failure caused by reasons unpredictable based
on scientific technology standards at the time of
shipment from Mitsubishi Electric.
[7] Any other failure found not to be the responsibility
of Mitsubishi Electric or that admitted not to be so
by the user.
