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 Qualied Personnel
Correct and reliable transport, storage, installation,
operation, and maintenance are required for the trouble-
free and safe operation of the frequency converter. Only
qualied personnel are allowed to install or operate this
equipment.
Qualied personnel are dened as trained sta, who are
authorised to install, commission, and maintain equipment,
systems, and circuits in accordance with pertinent laws and
regulations. Additionally, the qualied personnel must be
familiar with the instructions and safety measures
described in these operating instructions.
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 qualied personnel can result in death or serious
injury.
•
Installation, start-up, and maintenance must be
performed by qualied personnel only.
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 via an external
switch, a serial bus command, an input reference signal
from the LCP, 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.
•
Fully wire and assembly 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. Failure to wait the specied
time after power has been removed before performing
service or repair work, could result in death or serious
injury.
1. Stop motor.
2. Disconnect AC mains, permanent magnet type
motors, and remote DC-link power supplies,
including battery back-ups, UPS, and DC-link
connections to other frequency converters.
3. Wait for the capacitors to discharge fully, before
performing any service or repair work. The
duration of waiting time is specied in Table 2.1.

perform installation, start-up, and maintenance.
•
Ensure that electrical work conforms to national
and local electrical codes.
•
Follow the procedures in this manual.
WARNING
UNINTENDED MOTOR ROTATION
WINDMILLING
Unintended rotation of permanent magnet motors
creates voltage and can charge the unit, resulting in
death, serious injury, or equipment damage.
•
Ensure that permanent magnet motors are
blocked to prevent unintended rotation.
CAUTION
INTERNAL FAILURE HAZARD
An internal failure in the frequency converter can result
in serious injury, when the frequency converter is not
properly closed.

3.2 Installation Environments
NOTICE
In environments with airborne liquids, particles, or
corrosive gases, ensure that the IP/type rating of the
equipment matches the installation environment. Failure
to meet requirements for ambient conditions can reduce
the lifetime of the frequency converter. Ensure that
requirements for air humidity, temperature, and altitude
are met.
Vibration and shock
The frequency converter complies with requirements for
units mounted on the walls and oors of production
premises, as well as in panels bolted to walls or oors.
For detailed ambient conditions specications, refer to
chapter 8.4 Ambient Conditions.
3.3 Mounting
NOTICE
Improper mounting can result in overheating and
reduced performance.

For lifting, use the hoist rings on the unit, when
provided.
Mounting
1. Ensure that the strength of the mounting location
supports the unit weight. The frequency
converter allows side-by-side installation.
2. Locate the unit as near to the motor as possible.
Keep the motor cables as short as possible.
3. Mount the unit vertically to a solid at surface or
to the optional back plate to provide cooling
airow.
4. Use the slotted mounting holes on the unit for
wall mounting, when provided.
Mounting with back plate and railings
Illustration 3.3 Proper Mounting with Back Plate
NOTICE
A back plate is required when mounted on railings.
NOTICE
All A, B, and C enclosures allow side-by-side installation.
Exception: if an IP21 kit is used, there has to be a
clearance between the enclosures:
•
For enclosures A2, A3, A4, B3, B4 and C3, the

4 Electrical Installation
4.1 Safety Instructions
See chapter 2 Safety for general safety instructions.
WARNING
INDUCED VOLTAGE
Induced voltage from output motor cables that run
together can charge equipment capacitors, even with the
equipment turned o and locked out. Failure to run
output motor cables separately or use screened cables
could result in death or serious injury.
•
Run output motor cables separately, or
•
Use screened cables.
CAUTION
SHOCK HAZARD
The frequency converter can cause a DC current in the
PE conductor. Failure to follow the recommendation
means that the RCD may not provide the intended
protection.
•
When a residual current-operated protective
device (RCD) is used for protection against
electrical shock, only an RCD of Type B is
permitted on the supply side.
Overcurrent protection
•
Extra protective equipment, such as short-circuit
protection or motor thermal protection between
frequency converter and motor, is required for
applications with multiple motors.
•
Input fusing is required to provide short-circuit
and overcurrent protection. If not factory-
supplied, the installer must provide fuses. See
maximum fuse ratings in chapter 8.8 Fuses and
Circuit Breakers.
Wire type and ratings
•
All wiring must comply with local and national
regulations regarding cross-section and ambient
temperature requirements.
•
Power connection wire recommendation:
Minimum 75 °C rated copper wire.
See chapter 8.1 Electrical Data and chapter 8.5 Cable Speci-
cations for recommended wire sizes and types.
4.2 EMC Compliant Installation
To obtain an EMC-compliant installation, follow the
instructions provided in chapter 4.3 Grounding,
chapter 4.4 Wiring Schematic, chapter 4.6 Motor Connection,
and chapter 4.8 Control Wiring.
4.3 Grounding
WARNING
LEAKAGE CURRENT HAZARD
Leakage currents exceed 3.5 mA. Failure to ground the
frequency converter properly could result in death or
serious injury.
•
Ensure the correct grounding of the equipment
by a certied electrical installer.
For electrical safety
•
Ground the frequency converter in accordance
with applicable standards and directives.
•
Use a dedicated ground wire for input power,
motor power, and control wiring.
•
Do not ground one frequency converter to
another in a daisy chain fashion.
•
Keep the ground wire connections as short as
possible.
•
Follow motor manufacturer wiring requirements.
•
Minimum cable cross-section: 10 mm
2
(or 2 rated
ground wires terminated separately).
For EMC-compliant installation
•
Establish electrical contact between the cable
screen and the frequency converter enclosure by
using metal cable glands or by using the clamps
provided on the equipment (see chapter 4.6 Motor
Connection).
•
Use high-strand wire to reduce electrical
interference.
•
Do not use pigtails.
NOTICE
POTENTIAL EQUALISATION
Risk of electrical interference, when the ground potential
between the frequency converter and the control system
is dierent. Install equalising cables between the system
components. Recommended cable cross-section: 16 mm

Table 4.2 Terminal Description
Additional terminals:
•
2 form C relay outputs. Location of the outputs
depends on frequency converter conguration.
•
Terminals located on built-in optional equipment.
See the manual provided with the equipment
option.
4.8.2 Wiring to Control Terminals
Control terminal connectors can be unplugged from the
frequency converter for ease of installation, as shown in
Illustration 4.15.
NOTICE
Keep control wires as short as possible and separate
from high power cables to minimise interference.
1. Open the contact by inserting a small screwdriver
into the slot above the contact and push the
screwdriver slightly upwards.
