Basic Configuration Diagram
The reference diagram below shows a typical system configuration showing the inverter
and peripheral devices.
Prior to installing the inverter, ensure that the product is suitable for the application (power
rating, capacity, etc). Ensure that all of the required peripherals and optional devices
(resistor brakes, contactors, noise filters, etc.) are available. For more details on peripheral
devices, refer to 11.4 Peripheral Devices on page 419.
• Figures in this manual are shown with covers or circuit breakers removed to show a more
detailed view of the installation arrangements. Install covers and circuit breakers before
operating the inverter. Operate the product according to the instructions in this manual.
• Do not start or stop the inverter using a magnetic contactor, installed on the input power
supply.
• If the inverter is damaged and loses control, the machine may cause a dangerous situation.
Install an additional safety device such as an emergency brake to prevent these situations.
• High levels of current draw during power-on can affect the system. Ensure that
correctly rated circuit breakers are installed to operate safely during power-on
situations.
• Reactors can be installed to improve the power factor. Note that reactors may be
installed within 30 ft (9.14 m) from the power source if the input power exceeds 10
times 0f inverter capacity. Refer to 11.5 Fuse and Reactor Specifications on page 421
and carefully select a reactor that meets the requirements.
• 30-75kW models have a built-in DC Reactor.
