Precautions For Use - Fuji Electric P642 Series Applications Manual

1. Precautions for Use

•
This product shall be used within its maximum rating (voltage, current, temperature, and so on)
described in this specification. This product may be broken in case of using beyond the maximum
ratings. The specified value in the absolute maximum ratings are guaranteed value for the rating,
not for any combination of ratings or characteristics. Even if this product is used within absolute
maximum ratings, expected product lifetime may not be obtained depending on the temperature or
usage environment. Please refer to the absolute maximum rating of this product, and judge the
suitability of this product for your system / equipment after evaluation and verification by yourself.
•
It shall be confirmed that IGBT's operating locus of the turn-off voltage and current are within the
RBSOA specification. If the IGBT is used beyond the range of RBSOA, this product may be
destroyed.
•
If a voltage exceeding V
destroyed. Use this product so that V
• ​ F WD of this product is not designed to be used as a diode rectifier (AC-DC conversion circuit).
•
If a transient overvoltage that exceeds the voltage rating of the device in this product is propagated
from the electric power supply to this product due to a lightning strike, etc., the overvoltage may
destroy this product. If any transient overvoltage is expected to be applied from the electric power
supply to line-line or line-ground, insert a surge absorber, etc. to suppress the voltage applied to
this product in order to avoid damage.
•
This product is not designed for use in parallel connection, so it cannot be used in parallel
connection.
•
If applied Printed Circuit Board is not suitable, the main pin terminals may have higher temperature
than T (Case temperature). Also the main pin terminals shall be used within temperature range of
C
Tc (Case temperature).
•
This product are made of incombustible material. However, if this product fails, it may emit smoke
or flame. Also, operating this product near any flammable place or material may cause this product
to emit smoke or flame in case this product become even hotter during operation. Design the
arrangement to prevent the spread of fire.
•
Install surely a adequate fuse or breaker between the commercial power supply (three-phase line)
and this product in case the system / equipment is destroyed by an accident to prevent secondary
destruction such as fire, explosion, and fire spread.
•
Do not directly touch the leads or package of this product while power is supplied or during
operation in order to avoid electric shock and burns.
•
In any environment containing corrosive gases, corrosive liquids, corrosive solids (acids, alkalis,
organic substances, etc., ex: hydrogen sulfide, sulfurous acid gas, cutting fluid, cement powder etc.),
this product may oxidize or corrode, resulting in poor contact, disconnection, short circuit, ground
fault, etc. In such cases, avoid to use this product as it may cause malfunctions. In the unlikely
event that a short circuit or ground fault occurs to this product, there is a secondary risk of smoke,
fire, or explosion, etc. If this product is used under conditions containing these corrosive substances,
Fuji Electric Co., Ltd. is not responsible regardless of the conditions (temperature, humidity,
concentration, etc.).
