4-1 Preparation before turning power ON
Always confirm the following points before turning ON the power after completing wire.
(1) If problem can occur if the motor runs in reverse direction then remove the coupling and belt
coupling the motor and machine, so that the machine can be run as a single unit.
(2) Confirm that the power supply cables are correctly connected to the input terminals (L1, L2, and
L3).
(3) There are some sections in the inverter, which operate with an AC power supply, such as
fan/blower and magnetic contactor. In this case, select the appropriate tapping of the control
transformer on the control terminal block inside the unit. Remove the front cover to access the
control terminal block.
(4) Make sure that the power voltage and frequency is within the tolerable range.
(5) Refer to Chapter-2: Installation & Wiring and correctly connect the main circuit wiring.
(6) Securely fix the motor with the specified method.
(7) Make sure that none of the terminal section screws are loose.
(8) Make sure that there is no short circuit state in the terminals caused by wire scraps, etc.
