2 Safety
2.1 Safety Symbols
The following symbols are used in this guide:
WARNING
Indicates a potentially hazardous situation that could
result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation that could
result in minor or moderate injury. It can also be used to
alert against unsafe practices.
NOTICE
Indicates important information, including situations that
can result in damage to equipment or property.
2.2 Qualied Personnel
Correct and reliable transport, storage, installation,
operation, and maintenance are required for the troublefree and safe operation of the frequency converter. Only
qualied personnel are allowed to install or operate this
equipment.
Qualied personnel are dened as trained sta, who are
authorized to install, commission, and maintain equipment,
systems, and circuits in accordance with pertinent laws and
regulations. Also, the qualied personnel must be familiar
with the instructions and safety measures described in this
installation guide.
2.3
Safety Precautions
WARNING
HIGH VOLTAGE
Frequency converters contain high voltage when
connected to AC mains input, DC supply, or load sharing.
Failure to perform installation, start-up, and maintenance
by qualied personnel can result in death or serious
injury.
•
Only qualied personnel must perform installation, start-up, and maintenance.
WARNING
UNINTENDED START
When the frequency converter is connected to AC mains,
DC supply, or load sharing, the motor may 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 eldbus command, an input reference signal
from the LCP or LOP, via remote operation using MCT 10
Set-up Software, or after a cleared fault condition.
To prevent unintended motor start:
•
Press [O/Reset] on the LCP before
programming parameters.
•
Disconnect the frequency converter from the
mains.
•
Completely wire and assemble the frequency
converter, motor, and any driven equipment
before connecting the frequency converter to
AC mains, DC supply, or load sharing.
WARNING
DISCHARGE TIME
The frequency converter contains DC-link capacitors,
which can remain charged even when the frequency
converter is not powered. High voltage can be present
even when the warning LED indicator lights are o.
Failure to wait the specied time after power has been
removed before performing service or repair work can
result in death or serious injury.
•
Stop the motor.
•
Disconnect AC mains and remote DC-link
supplies, including battery back-ups, UPS, and
DC-link connections to other frequency
converters.
•
Disconnect or lock PM motor.
•
Wait for the capacitors to discharge fully. The
minimum waiting time is specied in the
chapter Safety in the operating instructions
supplied with the frequency converter.
•
Before performing any service or repair work,
use an appropriate voltage measuring device to
make sure that the capacitors are fully
discharged.
