1.  Safety Precautions (English) 
 
1.1 Before supplying Power to the Inverter 
 
The main circuit must be correctly wired. For single phase supply use input terminals (R/L1, T/L3) and for 
three phase supply use input terminals (R/L1, S/L2, T/L3). Terminals U/T1, V/T2, W/T3 must only be 
used to connect the motor. Connecting the input supply to any of the U/T1, V/T2 or W/T3 terminals will 
cause damage to the inverter. 
 
  To avoid the front cover from disengaging or other physical damage, do not carry the inverter by 
its cover. Support the unit by its 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 or near flammable objects. Install on 
nonflammable objects such as metal surfaces. 
 
  If several inverters are placed inside the same control enclosure, provide adequate ventilation to 
maintain the temperature below 40°C/104°F (50°C/122°F without a dust cover) to avoid 
overheating or fire. 
 
  When removing or installing the digital operator, turn off the power first, and then follow the 
instructions in this manual to avoid operator error or loss of display caused by faulty connections.
