LACK OF SAFETY AWARENESS
This guide provides important information on preventing injury and damage to the equipment or the system.
Ignoring this information can lead to death, serious injury, or severe damage to the equipment.
Make sure to fully understand the dangers and safety measures present in the application.
l
ELECTRIC SHOCK
Drives contain hazardous voltage when a power source is connected to AC or DC terminals. Failure to
disconnect all power sources can result in death or serious injury.
Before performing any electrical work on the drive, disconnect, lock out, and tag out all power sources to
l
the drive.
There is more than 1 live circuit. See the relevant wiring diagram in the product guide.
l
DISCHARGE TIME
The drive contains capacitors, which can remain charged even when the drive is not powered. High voltage
can be present even when the warning indicator lights are off.
Failure to wait the specified time after power has been removed before performing service or repair work
could result in death or serious injury.
Stop the drive.
l
Disconnect all input and output power sources of the drive (for example permanent magnet type motors,
l
batteries, or DC-link connections to other drives).
Wait for the capacitors to discharge fully before performing any service on the equipment. The discharge
l
time is 5 minutes. If the device is broken or fuses have tripped, the discharge time is longer.
Use a measuring device to make sure that there is no voltage, before opening the drive or performing any
l
work on the cables.
UNINTENDED START
When the drive is connected to a power source, the system may start at any time, causing risk of death, serious injury, and
equipment or property damage.
Stop the drive and motor before configuring parameters.
l
Make sure that the drive cannot be started by an external switch, a fieldbus command, an input reference signal from the
l
control panel, or after a cleared fault condition.
Disconnect the drive from the power source whenever safety considerations make it necessary to avoid unintended start.
l
Check that the drive, motor, and any driven equipment are in operational readiness.
l
