2.1 Safety Symbols
The following symbols are used in this manual:
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 and operate this
equipment.
Qualied personnel are dened as trained sta, who are
authorised to install, commission, and maintain equipment,
systems, and circuits in accordance with pertinent laws and
regulations. Additionally, the qualied personnel must be
familiar with the instructions and safety measures
described in these operating instructions.
Safety Precautions
2.3
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 instal-
•
lation, 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:
Disconnect the frequency converter from the
•
mains.
Press [O/Reset] on the LCP before
•
programming parameters.
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 that
can remain charged even when the frequency converter
is not powered. 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 the AC mains and remote DC-link
•
supplies, including battery back-ups, UPS, and
DC-link connections to other frequency
converters.
Disconnect or lock the PM motor.
•
Wait for the capacitors to discharge fully before
•
performing any service or repair work. The
waiting time is specied in the relevant
frequency converter operating instructions,
Chapter 2 Safety.
WARNING
LEAKAGE CURRENT HAZARD
Leakage currents exceed 3.5 mA. Failure to ground
frequency converter properly can result in death or
serious injury.
Ensure the correct grounding of the equipment
•
by a certied electrical installer.

Safety Installation Guide
WARNING
EQUIPMENT HAZARD
Contact with rotating shafts and electrical equipment
can result in death or serious injury.
Ensure that only trained and qualied personnel
•
perform installation, start-up, and maintenance.
Ensure that electrical work conforms to national
•
and local electrical codes.
Follow the procedures in this manual.
•
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.

See chapter 2 Safety for general safety instructions.
3.2 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
eldbus master manual from the PLC supplier for further
installation guidelines.
3.3 Grounding
3.4
NOTICE
EMC INTERFERENCE
Use screened cables for motor and control wiring, and
separate cables for eldbus communication, motor
wiring, and brake resistor. Failure to isolate eldbus
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 (450 hp), increase the minimum distance
of 500 mm (20 in).
NOTICE
When the eldbus cable intersects a motor cable or a
brake resistor cable, ensure that the cables intersect at
an angle of 90°.
Ensure that all stations connected to the eldbus
•
network are connected to the same ground
potential. When distances between the stations in
a eldbus network are long, 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.
To establish electrical contact between the cable
•
screen and the frequency converter enclosure,
use metal cable glands or the clamps provided
on the equipment.
Use high-strand wire to reduce burst transient.

1. Check whether the eldbus option is already
mounted in the frequency converter. If already
mounted, go to step 6. If not mounted, go to
step 2.
2. Remove the LCP or blind cover from the
frequency converter.

Wiring procedure for enclosure sizes A1–A3
1. Mount the eldbus connector on the eldbus
option (terminals 62, 63, 66, and 67). For top
cable entry, mount the supplied EMC bracket on
top of the frequency converter with 2 screws.
2. Prepare the eldbus cable by stripping a section
of the cable insulation, so that the cable screen is
in contact with the EMC bracket. Keep the
unshielded wire as short as possible. For cable
specications, refer to chapter 3.7.2 Cable Speci-
cations. For eldbus cable requirements, see
chapter 3.7.3 Bus Segment Requirements.
3. Connect the eldbus cable wires to the terminals
according to the colour code of the wires, see
