9.1 Safety Checks before Starting the Commissioning
Before starting the commissioning, read these warnings.
D A N G E R
SHOCK HAZARD FROM POWER UNIT COMPONENTS
The power unit components are live when the drive is connected to mains. A contact with this voltage can lead to death or seri-
ous injury.
Do not touch the components of the power unit when the drive is connected to mains. Before connecting the drive to mains,
make sure that the covers of the drive are closed.
D A N G E R
SHOCK HAZARD FROM TERMINALS
The motor terminals U, V, W, the brake resistor terminals, or the DC terminals are live when the drive is connected to mains, also
when the motor does not operate. A contact with this voltage can lead to death or serious injury.
Do not touch the motor terminals U, V, W, the brake resistor terminals, or the DC terminals when the drive is connected to
mains. Before connecting the drive to mains, make sure that the covers of the drive are closed.
D A N G E R
SHOCK HAZARD FROM DC LINK OR EXTERNAL SOURCE
The terminal connections and the components of the drive can be live 5 minutes after the drive is disconnected from the mains
and the motor has stopped. Also the load side of the drive can generate voltage. A contact with this voltage can lead to death or
serious injury.
Before doing 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.
Wait 5 minutes before opening the cabinet door or the cover of the AC drive.
Use a measuring device to make sure that there is no voltage.
W A R N I N G
SHOCK HAZARD FROM CONTROL TERMINALS
The control terminals can have a dangerous voltage also when the drive is disconnected from mains. A contact with this voltage
can lead to injury.
Make sure that there is no voltage in the control terminals before touching the control terminals.
C A U T I O N
BURNING HAZARD FROM HOT SURFACES
The surface of the side of the AC drive FR8 is hot.
Do not touch the side of the AC drive FR8 with hands when it operates.
C A U T I O N
FIRE HAZARD FROM HOT SURFACES
When the AC drive FR6 operates, the rear surface of the drive is hot, and can cause fire on the surface it is installed on.
Do not install the AC drive FR6 on a surface that is not fireproof.
