4. Additional instructions
Also note the following points to prevent an accidental failure, injury, electric shock, etc.:
(1) Transportation and installation
When carrying products, use correct lifting gear to prevent injury.
Do not stack the inverter boxes higher than the number recommended.
Ensure that installation position and material can withstand the weight of the inverter. Install
according to the information in the Instruction Manual.
Do not operate if the inverter is damaged or has parts missing.
Do not hold the inverter by the front cover; it may fall off.
Do not stand or rest heavy objects on the inverter.
Check the inverter mounting orientation is correct.
Prevent screws, wire fragments, conductive bodies, oil or other flammable substances from entering
Do not drop the inverter, or subject it to impact.
Use the inverter under the following environmental conditions:
••*Temperatures applicable for a short time, e.g. in transit.
Do not fit capacitive equipment such as a power factor correction capacitor, noise filter or surge
suppressor to the output of the inverter.
The connection orientation of the output cables U, V, W to the motor will affect the direction of
rotation of the motor.
(3) Trial run
Check all parameters, and ensure that the machine will not be damaged by a sudden start-up.
When you have chosen the retry function, stay away from the equipment as it will restart suddenly
after an alarm stop.
The [STOP] key is valid only when the appropriate function setting has been made. Prepare an
emergency stop switch separately.
Make sure that the start signal is off before resetting the inverter alarm. A failure to do so may restart
the motor suddenly.
