Mount the in v er te r oni n combustib le sur fa ce l i ke me ta l,an d kee p away from flammable s ubstances !
Otherwise it may cause fire.

Whenmore t han two invertersare tobe installed in one cabinet, pleasepay atte ntion to t he
installation locations to ensure the cooling effect (ref erto Chapter 3 Mechanicaland Electrical
In stall a tion) .
Do not drop the lead wire stubor screwin the inverter, or the inverter may bedamaged.

Do n ot c onnec tthe input ter minals with the output te rminals (U, V, W), otherwise the inverter
may be damaged!
Ensu re the wiring mee t the EM C r eq uirements an d the local s afety standard. The wire size shall
be det ermined according tot he manual, oth erwis e accident mayo ccur!

Do no t touc h the invert er ter m inals, other wise there will be danger of electri c shock.
At power-on, the inverter willperformthe security check ofthe external heavy-current circuit
automat ically, so at thistime pl ease d o not touch thete rmina ls U,V and W, or the te rmina ls of
motor, otherwise there will be danger ofelectric shock.
