~ 4 ~ This Operation Manual is intended to familiarize you with the unit, the requirements for safety, operation and maintenance procedures of the universal motor protection unit of UBZ-305 (hereinafter referred to as UBZ). ATTENTION! ALL REQUIREMENTS OF THIS OPERATION MANUAL ARE COMPULSORY TO BE MET!
For UBZ operation with PC the program of UBZ-304/305 Control Panel can be used; it is available on the website of NOVATEK-ELECTRO Company (http://www.novatek-electro.com/production_ubz.htm). UBZ-304/305 Control Panel program is designed to monitor the status and collect data of the UBZ-305 unit via RS-232 or RS-485 communication interfaces (MODBUS Protocol). The program allows for saving (loading) various UBZ settings, retrieving data and save them for further analysis.

ARS after tripping will not occur (regardless of the value of “I2 rev protec” parameter). The coefficient of negative voltage (current) sequence is characteristic of unbalance of three-phase voltage (current). Approximately the coefficient of negative voltage sequence is determined by the formula: NOVATEK-ELECTRO UBZ-305...
