Warnings
Do not touch the components of the power unit when the drive is connected to
mains. The components are live when the drive is connected to mains. A contact
with this voltage is very dangerous.
Do not touch the motor cable terminals U, V, W, the brake resistor terminals or the
DC terminals when the drive is connected to mains. These terminals are live when
the drive is connected to mains, also when the motor does not operate.
Do not touch the control terminals. They can have a dangerous voltage also when
the drive is disconnected from mains.
Before you do electrical work on the drive, disconnect the drive from the mains and
make sure that the motor has stopped. Lock out and tag out the power source to
the drive. Make sure that no external source generates unintended voltage during
work. Note that also the load side of the drive can generate voltage.
Wait 5 minutes before you open the cabinet door. Use a measuring device to make
sure that there is no voltage. The terminal connections and the components of the
drive can be live 5 minutes after it is disconnected from the mains and the motor
has stopped.
Before you connect the AC drive to mains, make sure that the coolant circulation
functions properly, and check the circulation for possible leaks.
Before you connect the drive to mains, make sure that the front cover and the cable
cover of the drive are closed. The connections of the AC drive are live when the
drive is connected to mains.
Before connecting the drive to mains make sure that the enclosure door is closed.
Disconnect the motor from the drive if an accidental start can be dangerous. When
there is a power-up, a power break or a fault reset, the motor starts immediately if
the start signal is active, unless the pulse control for Start/Stop logic is selected. If
the parameters, the applications or the software change, the I/O functions
(including the start inputs) can change.
Wear protective gloves when you do mounting, cabling or maintenance operations.
There can be sharp edges in the AC drive that can cause cuts.
Do not move the AC drive. Use a fixed installation to prevent damage to the drive.
