Maintenance
The BALDOR Series 10 inverters require very little maintenance, if any, and should provide years of trouble free operation when installed and applied correctly. Occasional visual inspection should be considered to insure tight wiring connections and to avoid the build up of any dust, dirt, or foreign debris. The control should be physically located in such a manner as to protect the internal circuits and associated external wiring from any accumulation of moisture or other types of liquid contaminants.
Before attempting to service this equipment, all input power should be removed from the inverter to avoid the possibility of electrical shock. The servicing of this equipment should be handled by a qualified electrical service technician experienced in the area of high power electronics.
