TECO E510s Series - 1.4 During Operation; 1.5 Maintenance, Inspection and Replacement

1-3
 Reduce the carrier frequency (parameter 11-01) If the cable from the inverter to
the motor is greater than 80 ft (25m). 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
Caution
 When the power is applied, inverter will show the voltage rating on display for 2
seconds according to the setting value of parameter 01-14.
 Do not connect a load to the motor while performing a rotational auto-tune.
 Make sure it is safe to operate the inverter and motor before performing a
rotational auto-tune.
1.4 During Operation
Danger
 Be sure to install all covers before turning on power
 Do not connect or disconnect the motor during operation. Otherwise, It may
cause the inverter to trip or damage the unit.
 Please do not close to the equipment when the reset function is performed,
equipment will restart the fault has been removed.
 Do not operate switches with wet hands, otherwise electric shock may result
 The motor will restart automatically after stop when auto-restart function is
enabled. In this case, care must be taken while working around the drive and
associated equipment.
 Confirm that no run command is active upon resetting the alarm or fault,
otherwise accidents may occur.
 If automatic restart after power recovery (parameter 07-00) is enabled, the
inverter will start automatically after power is restored
 Do not touch inverter terminals when energized even if inverter has stopped,
otherwise electric shock may result.
 It is not permissible to open the equipment until 5 minutes after the power has
been removed.。(if the inverter rating is 15HP above, please open the equipment
until 15 minutes after the power has been removed.
Caution
 Do not touch heat-generating components such as heat sink and braking resistors.
 Carefully check the performance of motor or machine before operating at high
speed, otherwise Injury may result.
 Note the parameter settings related to the braking unit when applicable.
 After the power is turned off, the cooling fan may continue to run for some time.
 Do not check signals on circuit boards while the inverter is running.
1.5 Maintenance, Inspection and Replacement
Warning
 Wait a minimum of five minutes after power has been turned OFF before starting
an inspection. Also confirm that the charge light is OFF and that the DC bus
voltage has dropped below 25Vdc.
 Never touch high voltage terminals in the inverter.
