2 Safety
2.1 Safety Symbols
The following symbols are used in this document:
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 Qualified Personnel
Correct and reliable transport, storage, installation,
operation, and maintenance are required for the trouble-
free and safe operation of the frequency converter. Only
qualified personnel are allowed to install or operate this
equipment.
Qualified personnel are defined as trained staff, who are
authorised to install, commission, and maintain equipment,
systems, and circuits in accordance with pertinent laws and
regulations. Additionally, the qualified personnel must be
familiar with the instructions and safety measures
described in this document.
2.3 Safety Precautions
WARNING
HIGH VOLTAGE
Frequency converters contain high voltage when
connected to AC mains input, DC power supply, or load
sharing. Failure to perform installation, start-up, and
maintenance by qualified personnel can result in death
or serious injury.
•Installation, start-up, and maintenance must be
performed by qualified personnel only.
WARNING
UNINTENDED START
When the frequency converter is connected to AC mains,
DC power 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 by means of an
external switch, a serial bus command, an input
reference signal from the LCP or LOP, via remote
operation using MCT 10 software, or after a cleared fault
condition.
To prevent unintended motor start:
•Disconnect the frequency converter from mains.
•Press [Off/Reset] on the LCP, before
programming parameters.
•The frequency converter, motor, and any driven
equipment must be fully wired and assembled
when the frequency converter is connected to
AC mains, DC power 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. Failure to wait the specified
time after power has been removed before performing
service or repair work, can result in death or serious
injury.
•Stop motor.
•Disconnect AC mains and remote DC-link power
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, before
performing any service or repair work. The
duration of waiting time is specified in the
relevant frequency converter Operating
Instructions, Chapter 2 Safety.

WARNING
LEAKAGE CURRENT HAZARD
Leakage currents exceed 3.5 mA. Failure to ground the
frequency converter properly can result in death or
serious injury.
•Ensure the correct grounding of the equipment
by a certified electrical installer.
WARNING
EQUIPMENT HAZARD
Contact with rotating shafts and electrical equipment
can result in death or serious injury.
•Ensure that only trained and qualified
personnel perform installation, start up, and
maintenance.
•Ensure that electrical work conforms to national
and local electrical codes.
•Follow the procedures in this document.
CAUTION
INTERNAL FAILURE HAZARD
An internal failure in the frequency converter can result
in serious injury, when the frequency converter is not
properly closed.
•Ensure that all safety covers are in place and
securely fastened before applying power.

3 Installation
3.1 Safety Instructions
See chapter 2 Safety for general safety instructions.
3.2 Mounting
1. Check whether the fieldbus option is already
mounted in the frequency converter. If already
mounted, go to step 6.
2. Remove the LCP or blind cover from the
frequency converter.
3. Use a screwdriver to remove the front cover and
the LCP cradle.
4. Mount the fieldbus option. Mount the option
with the Ethernet port facing up for top cable
entry (see Illustration 3.2).
5. Remove the knock-out plate from the new LCP
cradle.
6. Mount the new LCP cradle.

3.3 EMC-compliant Installation
To obtain an EMC-compliant installation, follow the
instructions provided in the relevant frequency converter
Operating Instructions and Design Guide. Refer to the
fieldbus master manual from the PLC supplier for further
installation guidelines.
3.4 Grounding
•Ensure that all stations connected to the fieldbus
network are connected to the same ground
potential. When there are long distances between
the stations in a fieldbus network, connect the
individual station to the same ground potential.
Install equalising cables between the system
components.
•Establish a grounding connection with low HF
impedance, for example by mounting the
frequency converter on a conductive back plate.
•Keep the ground wire connections as short as
possible.
3.5 Cable Routing
NOTICE
EMC INTERFERENCE
Use screened cables for motor and control wiring, and
separate cables for fieldbus communication, motor
wiring, and brake resistor. Failure to isolate fieldbus
communication, motor, and brake resistor cables can
result in unintended behaviour or reduced performance.
Minimum 200 mm (7.9 in) clearance between power,
motor, and control cables is required. For power sizes
above 315 kW, it is recommended to increase the
minimum distance of 500 mm (20 in).
NOTICE
When the fieldbus cable crosses a motor cable or a brake
resistor cable, ensure that the cables cross at an angle of
90°.

3.6 Topology
The PROFINET module features a built-in Ethernet switch
with 2 Ethernet RJ 45/M12 connectors. The module
enables the connection of several PROFINET options in a
line topology as an alternative to a traditional star
topology. The 2 ports are equal. Select and use the 2 ports
freely.
Star Topology
130BC929.10
Illustration 3.5 Star Topology
Line Topology
In many installations, line topology enables simpler cabling
and the use of smaller Ethernet switches. The PROFINET
interface supports line topology with its 2 ports and built-
in Ethernet switch.
When line topology is used, take precautions to avoid
timeout in the PLC when more than 8 frequency
converters are installed in series. Each frequency converter
in the network adds a small delay to the communication
due to the built-in Ethernet switch. When the update time
is too short, the delay can lead to timeout in the PLC. Set
the update time as shown in Table 3.1. The numbers given
are typical values and can vary from installation to instal-
lation.

Table 3.1 Minimum Update Time
130BC930.10
Illustration 3.6 Line Topology
NOTICE
In a line topology, activate the built-in switch by
powering all frequency converters, either by mains or a
24 V DC option card.
NOTICE
Installing frequency converters of different power sizes
in a line topology may result in unwanted power-off
behaviour while using controlword timeout (8-02 Control
Word Source to 8-06 Reset Control Word Timeout). It is
recommended to mount the frequency converters with
the longest discharge time first in the line topology. In
normal operation, the larger power size frequency
converters have a longer discharge time.
