Hitachi Industrial Equipment Systems Co. , Ltd. L2002 Inverter i Safety Messages For the best results with the L2002 Series inverter, carefully read this manual and all of the warning labels attached to the inverter before installing and operating it, and follow the instructions exactly. Keep this manual handy for quick reference. Definitions and Symbols A safety instruction (message) includes a "Safety Alert Symbol" and a signal word or phrase such as WARNING or CAUTION. Each signal word has the following meaning: HIGH VOLTAGE: This symbol indicates high voltage. [. . . ] The settings cannot be edited via the network, in order to ensure network reliability. Refer to "ModBus Network Communications" on page B­1 for more information on controlling and monitoring your inverter from a network. "C" Function Func.

You can select any two of the other nine intelligent output options for internal inputs. Then, configure the logic function to apply the logical AND, OR, or XOR (exclusive OR) operator as desired to the two inputs. [. . . ] If two cables intersect (one crosses over the other), the interference is smallest if they intersect at an angle of 90°. Cables susceptible to interference should therefore only intersect motor cables, intermediate circuit cables, or the wiring of a rheostat at right angles and never be laid parallel to them over longer distances. Minimize the distance between an interference source and an interference sink (interference-threatened device), thereby decreasing the effect of the emitted interference on the interference sink. · You should use only interference-free devices and maintain a minimum distance of 0. 25 m from the adjustable frequency inverter.
