•
Any person who is opening a package using a sharp object, such as a knife and cutter, must wear gloves to prevent injuries caused by the
edge of the sharp object.
•
The product must be transported in an appropriate method for the weight of the package. Failure to do so may lead to injuries.
•
Do not stand or rest heavy objects on the product.
•
Do not stack the boxes containing soft starters higher than the number recommended.
•
During installation, caution must be taken not to drop the soft starter as doing so may cause injuries and damage to the product.
•
The product must be installed against a surface that withstands the weight of the soft starter.
•
Do not install the product on a hot surface.
•
The mounting orientation of the soft starter must be correct.
•
The soft starter must be installed on a strong surface securely with screws so that it will not drop.
•
Do not install or operate the soft starter if it is damaged or has parts missing.
•
Foreign conductive objects must be prevented from entering the soft starter. That includes screws and metal fragments or flammable
substance such as oil.
•
As the soft starter is a precision instrument, do not drop or subject it to impact.
•
For the all ranges of the soft starter, the surrounding air temperature must be 0 to +50°C - 0therwise the soft starter may be damaged.
•
The ambient humidity specification must be adhered to. Otherwise the soft starter may be damaged. (Refer to par 2.2.2.2 for details.)
•
The storage temperature (applicable for a short time, e.g. during transit) specification must be adhered to. Otherwise the soft starter
may be damaged.
•
The soft starter must be used indoors (without corrosive gas, flammable gas, oil mist, dust and dirt etc.) Otherwise the soft starter may
be damaged.
•
The soft starter can be used as rated, at an altitude of 1400 m or less above sea level. Higher altitudes require de-rating.
•
The soft starter should not be subjected to operational vibration. The soft starter is designed for transportation vibration only. (Refer to
paragraph 2.2.2.7 for details.)
•
If halogen-based materials (fluorine, chlorine, bromine, iodine, etc.) infiltrate into a Mitsubishi Electric product, the product will be
damaged. Halogen-based materials are often included in fumigant, which is used to sterilize or disinfest wooden packages. When
packaging, prevent residual fumigant components from being infiltrated into Mitsubishi Electric products, or use an alternative
sterilization or disinfection method (heat disinfection, etc.) for packaging. Sterilization or disinfection of wooden package should also be
performed before packaging the product.
•
The motor side terminals (terminals T1, T2 and T3) must be connected correctly. The soft starter will protect against phase reversal if
configured to do so. If the soft starter is configured to not check the phase rotation, the motor will rotate inversely – which may, or may
not be a problem in the installation.
•
Never connect the motor side terminals (terminals T1, T2 and T3) to the grid power supply. Applying the grid power supply to motor
terminals (T1, T2, T3) will damage the soft starter. The induction motor may be connected to the grid power supply only via a bypass
contactor that is under control of the soft starter.
•
Return wires from an Inside Delta motor connection should be connected to the Supply lines on L1, L2, L3 (and NOT on the Bypass
terminals BL1 BL2 BL3)
•
Before starting operation, each configuration parameter must be adjusted for the installation and motor size. A failure to do so may cause
unexpected behaviour or damage to the motor.
.
•
An independent hardware Emergency Stop must be provided as a safety measure to prevent hazardous conditions to the machine and
equipment in case of soft starter failure (refer paragraph ).
•
When the breaker on the soft starter input side trips, the wiring must be checked for fault (short circuit). The cause of the trip must be
identified and removed before turning ON the power on the breaker.
•
When a fuse on the soft starter input blows, the wiring and the soft starter needs to be checked for faults. The cause of the blown fuse
must be identified and removed before replacing the fuse and turning on again.
•
When a protective function activates, take appropriate corrective action, then reset the soft starter and resume the operation.
•
Do not carry out a megger (insulation resistance) test on the soft starter when connected. It may cause damage.
•
When unserviceable, the soft starter should be treated as industrial waste.
