1.3 During operation
Danger
Do not connect or disconnect the motor while inverter is operating the motor. The inverter
and the disconnect device can sustain damage from high levels of switch-off current
transients.
Danger
z
To avoid electric shock, do not take the front cover off while power is on.
z
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 .
z
The operation of the stop switch is different than that of the emergency stop switch. The stop
switch has to be activated to be effective. Emergency stop has to be de-activated to become
effective.
Caution
z
Do not touch heat-generating components such as heat sinks and brake resistors.
z
The inverter can drive the motor from low speed to high speed. Verify the allowable speed
ranges of the motor and the associated machinery.
z
Note the settings related to the braking unit.
z
Do not check signals on circuit PCB while the inverter is running.
Caution
Risk of electric shock. The DC link capacitors remain charged for five minutes after power
has been removed. It is not permissible to open the equipment until 5 minutes after the
power has been removed.
1.4 Useable environment
Caution
When the IP20 inverter top dust cover has been removed the drive can be installed in a
non-condensing environment with temperature ranging between –10 degree C to +50
degree C
and relative humidity of 95% or less, but the environment should be free from
water and metal dust.
