Chapter 1 Safety Precautions
1.1 Before Supplying Power to the Inverter
Warning
 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.
Caution
 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 panel, 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.
Warning
 This product is sold subject to IEC 61800-3. In a domestic environment this product may
cause radio interference in which case the user may need to apply corrective measures.
 Over temperature protection function on motor is provided, please follow the description of
control circuit terminals, and refer to the parameter group 08.
1.2 Wiring
Warning
 Always turn OFF the power supply before attempting inverter installation and wiring of the
user terminals.
 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.) It is required
to disconnect the ground wire in the control board to avoid the sudden surge causing
damage on electronic parts if it is improperly grounded.
 Please check and test emergency stop circuits after wiring. (Installer is responsible for the
correct wiring.)
 Never touch any of the input or output power lines directly or allow any input or output
power lines to come in contact with the inverter case.
 Do not perform a dielectric voltage withstand test (megger) on the inverter or this will result
in inverter damage to the semiconductor components.
Caution
 The line voltage applied must comply with the inverter’s specified input voltage.
 Connect braking resistor and braking unit to the designated terminals.
 Do not connect a braking resistor directly to the DC terminals P(+) and N(-),otherwise fire
may result.
 Use wire gauge recommendations and torque specifications.
 Never connect input power to the inverter output terminals U/T1, V/T2, W/T3.
 Do not connect a contactor or switch in series with the inverter and the motor.
