• An inverter drive kit could be structured to operate by connecting to DDC (automated control).

• An inverter drive kit can operate either in a contact point method or in a voltage method.

• In a voltage method, 0-10 V or 2-10 V can be selected for use, and refer to the next page for set

up method.
