strike. Department for frequent thunder and lightning, users should install the drive
front‐endprotection.
Derating due to altitude
Deratingmustbeconsidered whenthe driveis installedat highaltitude, greaterthan
1000m. Because of the thin air, the cooling effect of drive is deteriorated. Please
contactourtechnicaladviceinthiscase.
Special usage
If users need the wiring diagram, such as common DC bus, without in the manual,
Pleaseconsultourcompany.
Disposing unwanted drive
The capacitors may explode when they are burnt. Poisonous gas may be generated
when the plastic parts like front covers are burnt. Disposing method: Please dispose

2) Because the cooling fan of non‐inverter motor is coaxial connection with its
rotor shaft
connection, if the speed of the motor is reduced, the cooling effect of the fan is
deteriorating, if the motor may become overheating in the situation, please change to
