Safety Precautions
1-3
1.1.5 During operation
Danger
Do not connect or disconnect the motor while
iDrive
is operating otherwise the inverter
and/or the disconnecting device may be damaged by the high level of switch-off current.
Danger
To avoid electric shock, do not remove the front cover when power is on.
After a power-loss (under-volt) trip occurs, the motor will restart automatically when power is restored
if auto-restart function is set. In this case, care must be taken while working with the machine.
Note: External Emergency stop must mechanically open and un-latch the power supply to the
iDrive
without any chance of re-closing until required. It is not permitted to rely upon software
control for an emergency stop.
Caution
Do not touch heat-generating components such as heat sink and brake resistor.
The inverter can operate the motor from low speeds to very high speeds.
Verify the allowable speed ranges of the motor and the load before operation.
Note the settings related to the braking unit.
Do not check signals on circuit PCB while the inverter is running.
Caution
Allow a minimum of 5 minutes for
iDrive
to discharge after power down before attempting
to disassemble or checking the components within the drive.
1.1.6 Operating environment
Caution
iDrive
can be used in a non-condensing atmosphere in temperature range from -10
o
C to
+50
o
C and relative humidity of 95%, but the environment should be free from corrosive or
explosive gasses, condensation or conductive dust.
