Prohibited
 Do not connect input power to the output (motor side) terminals (U/T1,V/T2,W/T3).
That will destroy the inverter and may result in fire.
 Within 15 minutes after turning off input power, do not touch wires of devices (MCCB)
connected to the input side of the inverter.
That could result in electric shock.

Mandatory
action
 Electrical installation work must be done by a qualified expert.
Connection of input power by someone who does not have that expert knowledge may
result in fire or electric shock.
 Connect output terminals (motor side) correctly.
If the phase sequence is incorrect, the motor will operate in reverse and that may result in
injury.
 Wiring must be done after installation.
If wiring is done prior to installation that may result in injury or electric shock
 The following steps must be performed before wiring.
(1) Turn off all input power.
(2) Wait at least 15 minutes and check to make sure that the charge lamp is no longer lit.
If these steps are not properly performed, the wiring will cause electric shock.
 Tighten the screws on the terminal board to specified torque.
If the screws are not tightened to the specified torque, it may lead to fire.
 Check to make sure that the input power voltage is +10%, -15% of the rated power
voltage written on the rating label (±10% when the load is 100% in continuous operation).
If the input power voltage is not +10%, -15% of the rated power voltage (±10% when the
load is 100% in continuous operation) this may result in fire.
 Set a parameter f109 when VIA or VIB terminals are used as logic input terminal.
If it is not set, it could result in malfunction.
