81. Manual GuideEaton Electric General Inverters DF1 Series UMXXXXXXXXE February 2020 www.eaton.com1. Manual Guide1.1 Safety instructionsThank you for choosing Eaton inverters of DF1 series. This instruction introduces how to correctly use this inverter.Before using this inverter, always carefully read this User Manual and moreover, please understand the safety instruc-tions.Safety Instructions• Installation, operation, maintenance and inspection must be performed by qualified personnel.• In this instruction, the safety instruction levels are classified into “Warning” and “Caution”.Warning: Incorrect handling may cause hazardous conditions, resulting in death or severe injury.Caution: Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or maycause only material damage.Warning• While the inverter power is ON, do not open the front cover or the wiring cover. Do not run the inverter with thefront cover or the wiring cover removed. Otherwise you may access the exposed high voltage terminals or thecharging part of the circuitry and get an electric shock.• It is crucial to turn off the motor drive power before any wiring installation or inspection is made. Before the inverterCHARGE light is OFF, which indicates that there is still high voltage in it, please do not touch the internal circuit andcomponents. Operation must be made after measuring the voltage which is less than 24 VDC between +/P and -/Nand with avometer.• The inverter must be connected to the ground properly.• Do not operate or touch the radiator or handle the cables with wet hands. Otherwise you may get an electric shock.• Do not change the cooling fan while power is ON. It is dangerous to change the cooling fan while power is ON.Caution• The voltage applied to each terminal must be the ones specified in the Instruction Manual. Otherwise burst, dam-age, etc. may occur.• Do not conduct a pressure test on the components inside the inverter, for semiconductor of the inverter is easily tobe broke down and damaged by high voltage.• While power is ON or for some time after power-OFF, do not touch the inverter as it will be extremely hot. Touchingthese devices may cause a burn.• The cables must be connected to the correct terminals. Otherwise burst, damage, etc. may occur.• The polarity (+ and -) must be correct. Otherwise burst, damage, etc. may occur.• Inverter must be installed on a nonflammable wall without holes (so that nobody touches the inverter heatsink onthe rear side, etc.). Mounting it to or near flammable material may cause a fire.• If the inverter has become faulty, the inverter power must be switched OFF. A continuous flow of large current maycause a fire.• Do not connect a resistor directly to the DC terminals +/P and -/N. Doing so could cause a fire.
