Maintenance, Inspection And Replacement - TECO A510s Series Instruction Manual

 Operations may start suddenly if an alarm or fault is reset with a run command active.
Confirm that no run command is active upon resetting the alarm or fault, otherwise
accidents may occur.

Do not operate switches with wet hands, otherwise electric shock may result.

It provides an independent external hardware emergency switch, which emergently shuts down the
inverter output in the case of danger.

If automatic restart after power recovery (parameter 07-00) is enabled, the inverter will start
automatically after power is restored.

Make sure it is safe to operate the inverter and motor before performing a rotational auto-tune.
 Do not touch inverter terminals when energized even if inverter has stopped, otherwise
electric shock may result.
 Do not check signals on circuit boards while the inverter is running.
After the power is turned off, the cooling fan may continue to run for some time.
Caution

Do not touch heat-generating components such as heat sinks 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.

Do not use the inverter braking function for mechanical holding, otherwise injury may result.
Do not check signals on circuit boards while the inverter is running.

1.6 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.

Make sure power to the inverter is disconnected before disassembling the inverter.

Only authorized personnel should perform maintenance, inspection, and replacement operations.
(Take off metal jewelry such as watches and rings and use insulated tools.)
Caution

The Inverter can be used in an environment with a temperature range from 14° ~104(140) °F
(-10~+40(60)°C) and relative humidity of 95% non-condensing.

The inverter must be operated in a dust, gas, mist and moisture free environment.
