5.1 Safety Instructions
for general safety instructions.
W A R N I N G
INDUCED VOLTAGE
Induced voltage from output motor cables that run together can charge equipment capacitors, even with the equipment turned
off and locked out. Failure to run output motor cables separately or to use shielded cables could result in death or serious injury.
Run output motor cables separately.
Use shielded cables.
W A R N I N G
UNINTENDED START
When the soft starter is connected to AC mains, DC supply, or load sharing, the motor can start at any time. Unintended start
during programming, service, or repair work can result in death, serious injury or property damage. The motor can start with an
external switch, a fieldbus command, an input reference signal from the LCP, or after a cleared fault condition.
Press [Off/Reset] on the LCP before programming parameters.
Disconnect the soft starter from the mains.
Completely wire and assemble the soft starter, motor, and any driven equipment before connecting the soft starter to AC
mains, DC supply, or load sharing.
Fit the power supply to the soft starter with an isolating switch and a circuit-breaking device (for example a power contactor)
controllable through an external safety system (for example an emergency stop or a fault detector).
5.2 Command Source
Start and stop the soft starter via the digital inputs, remote LCP 601, communication network, smart card, or scheduled auto-start/
stop. Set up the command source via
Set-up Tools
or via
parameter 1-1 Command Source
.
If the remote LCP is installed, the [CMD/Menu] key provides shortcut access to the Command Source function in
Setup Tools
.
