Air duct is blocked or the cooling fan is damaged; ensure enough space for heat dissipation. 5. Manual Access
If the inverter alarms or shuts down, check the display for error codes: Jte Inverter Manual
The JTE series typically features a digital control panel with the following primary buttons: : Enter or exit the programming mode. ENTER : Confirm parameter settings or selection. UP/DOWN ( ) : Adjust frequency or change parameter values. Air duct is blocked or the cooling fan
Lower carrier frequency (2 kHz) reduces electrical noise but increases motor audible whine. Higher carrier (8 kHz) is silent but increases inverter heat. Default is 4 kHz. ENTER : Confirm parameter settings or selection
: Never connect three-phase power supply to the output terminals ( U, V, W ). Doing so will damage the internal components.
The dry contact is a relay output (normally open/closed) that triggers when the inverter is in fault or battery low mode. The manual provides wiring examples to connect an external buzzer or generator auto-start module.
