Chapter 1 Safety Precautions 
1.1  Before Power Up 
  Danger 
  Make sure the main circuit connections are correct Single phase L1(L),L3(N), Three 
phase L1(L),L2,L3(N) are power-input terminals and must not be mistaken for 
T1,T2 and T3. Otherwise, inverter damage can result. 
 Caution 
  The line voltage applied must comply with the inverter’s specified input 
voltage.(See the nameplate) 
  To avoid the front cover from disengaging, or other damge do not carry the 
inverter by its covers. Support the drive by the heat sink when transporting.   
Improper handling can damage the inverter or injure personnel and should be 
avoided. 
  To avoid the risk of fire, do not install the inverter on a flammable object.Install on 
nonflammable objects such as metal 
  This product provides the 10V/24V for internal use only, do not use as the power 
supply sources for other external components, such as sensors, electronic 
components ... etc., otherwise it will cause adverse situation. 
  When disconnecting the remote keypad, turn the power off first to avoid any 
damage to the keypad or the inverter. 
 Caution 
 
This product is sold subject to EN 61800-3 and EN 61800-5-1. In a domestic 
environment this product may cause radio interference in which case the user 
may be required to apply corrective measures.
 
  This product offers motor over temperature protection function. 
 Caution 
  Work on the device/system by unqualified personnel or failure to comply with 
warnings can result in severe personal injury or serious damage to material. Only 
suitably qualified personnel trained in the setup, installation, commissioning and 
operation of the product should carry out work on the device/system. 
  Only permanently-wired input power connections are allowed. 
1.2  During Power Up 
 Danger 
  Always turn OFF the power supply before attempting inverter installation and 
wiring of the user terminals. 
  Wiring must be performed by a qualified personnel / certified electrician. 
  Make sure the inverter is properly grounded. (200V Class: Grounding impedance 
shall be less than 100Ω. 400V Class: Grounding impedance shall be less than 10Ω.) 
Please connect to the earth according to EN61800-5-1 standard request, For 
system 430, 440, 450, 460 and 470, wiring size must be at least 10mm
2
(8 AWG) 
only can comply the standard of leakage current.
