Frequently Asked Questions
Q1: What is the range of input electricity for TOSVERT VF-A5 inverter?
A1: The TOSVERT VF-A5 inverter is designed to work with a 200v range of 0.4 to 55kw and 400v range of 0.75 to 75.
Q2: Is it possible to use TOSVERT VF-A5 inverter with single phase motors?
A2: This type of inverter is intended only for 3-phase induction motors and cannot be used with single-phase motors.
Q3: What Precautions Should Be Taken For Inverter Installation?
A3: An inverter needs to be set up where it will not get wet and breathable space is available before it can be set up because it is extremely sensitive to dust and gasses that promote rust.
Q4: What to Do When an Inverter Overheats and Triggers an Over Load Cutoff?
A4: Under any circumstance an inverter is not self resetting, therefore once it begins an over load cycle it will have to cool off for a minute in order to reset.
Q5: Can TOSVERT VF-A5 Become Functional by Itself After a Cutout?
A5: Some times an inverter can set itself back into operation after has tripped, for this to happen time needs to be set.
Q6: Are There External Braking Resistors For Inverters Greater In Wattage Over 3.7kW?
A6: For higher wattages like 3.7kW or larger external braking resistors are required as these cannot be built in.
Q7: Is There a Basic Install of Emergency Shut Off?
A7: Genuinely for emergency shut downs an inverter needs two stop/reset commands in order to switch off fully.
Q8: What Is Temperature Threshold Required For the Inverter to Work?/ What Threshold Can Cause Overheating?
A8: Ideally to be in the range of -10 degrees to 40 degrees Celsius; however for units that do not possess outer coverings it is essential to have a range of up to 50 degrees celsius.
