TECO L510 - Before Operation; Parameter Setting

1-3
1.3 Before Operation
Warning
 Make sure the inverter capacity matches the parameters 13-00.
 Reduce the carrier frequency (parameter 11-01) If the cable from the inverter to the motor is
greater than 80 ft (25m), refer to table 3.14.1. A high-frequency current can be generated by stray
capacitance between the cables and result in an overcurrent trip of the inverter, an increase in
leakage current, or an inaccurate current readout.
 Be sure to install all covers before turning on power. Do not remove any of the covers while power to
the inverter is on, otherwise electric shock may occur.
 Do not operate switches with wet hands, otherwise electric shock may result.
 Do not touch inverter terminals when energized even if inverter has stopped, otherwise electric shock
may result.
1.4 Parameter Setting
Caution
 Do not connect a load to the motor while performing a rotational auto-tune.
 Make sure the motor can freely run and there is sufficient space around the motor when
performing a rotational auto-tune.
