Product Description
14.F4.F1G-4I14 is an F4 series frequency inverter. It is designed by KEB Automation for 3-phase AC motor control. The inverter size designation is 14. Its voltage class is 400 Volts: the input current is 18 Amps for input voltages between 305 and 440 Volts and 15 Amps for input voltages between 460 to 500 Volts. The inverter produces three-phase output: the output current is 16.5 Amps at 440 Volts and 14 Amps at 480 Volts. The rated power output of the 14.F4.F1G-4I14 inverter is 11 kVA. It is compatible with 2/4 pole motors that have maximum 7.5 kilowatts power rating. Rated operating frequency of the unit is 16 kilohertz. The nominal operating power loss is 260 Watts. KEB has designed the unit for vertical installation. This is an IP20 rated unit which is not safe from water or dust ingress.
When installed inside a control cabinet, at least 100 millimeters of spacing must be provided on top and bottom of the mounted unit. The cool air inlet and warm air outlet are located at the bottom and top of the inverter, respectively. A heat sink is also installed, and its maximum permitted surface temperature is 90 degrees Celsius. The line used for the motor connection must be shielded and its maximum length can be 100 meters. Optimal inverter operation requires ambient conditions that comply with recommendations made by KEB. The optimal temperature range is from -10 to 45 degrees Celsius and the limit for non-condensing relative humidity is 95%. Electromagnetic Compatibility (EMC) for the inverter has been tested and complies with EN 61800-3. The climatic category, as per EN 50178, is 3K3.
