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 personnel must be familiar
with the instructions and safety measures described in this
manual.
2.3 Safety
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 the
mains.
•Press [Off/Reset] on the LCP before
programming parameters.
•Ensure that the frequency converter is fully
wired and assembled when it is connected to
AC mains, DC power supply, or load sharing.
WARNING
DISCHARGE TIME!
Frequency converters contain DC-link capacitors that can
remain charged even when the frequency converter is
not powered. To avoid electrical hazards, disconnect AC
mains, any permanent magnet type motors, and any
remote DC-link power supplies, including battery
backups, UPS and DC-link connections to other
frequency converters. Wait for the capacitors to fully
discharge before performing any service or repair work.
The amount of waiting time is listed in Table 2.1. Failure
to wait the specified time after power has been removed
before doing service or repair could result in death or
serious injury.

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 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.
2.4 Motor Thermal Protection
Set 1-90 Motor Thermal Protection to [4] ETR trip 1 to enable
the motor thermal protection function.

3.2.2 IT Mains
CAUTION
IT Mains
Installation on isolated mains source, that is, IT mains.
Ensure the supply voltage does not exceed 440 V
(3x380-480 V units) when connected to mains.
On IP20, 200-240 V, 0.25-11 kW (0.33-15 HP) and 380-480
V, IP20, 0.37-22 kW (0.5-30 HP) units, open the RFI switch
by removing the screw on the side of the frequency
converter when at IT grid.

3.2.3 Connecting to Mains and Motor
The frequency converter is designed to operate all
standard 3-phase asynchronous motors. For maximum
cross-section on cables, see chapter 6.4 General Technical
Data.
•Use a shielded/armored motor cable to comply
with EMC emission specifications, and connect
this cable to both the decoupling plate and the
motor.
•Keep the motor cable as short as possible to
reduce the noise level and leakage currents.
•For further details on mounting the decoupling
plate, see FC 101 De-coupling Plate Mounting
Instruction.
•Also see EMC-Correct Installation in the FC 101
Design Guide.
1. Mount the ground cables to the ground terminal.
2. Connect the motor to terminals U, V, and W, and
tighten the screws according to the torques
specified in chapter 3.2.1 Electrical Installation in
General.
3. Connect the mains supply to terminals L1, L2,
and L3, and tighten the screws according to the
torques specified in chapter 3.2.1 Electrical Instal-
lation in General.

3.2.4 Fuses and Circuit Breakers
Branch circuit protection
To protect the installation against electrical and fire hazard,
all branch circuits in an installation, switch gear, machines
etc., must be short-circuit and overcurrent protected
according to national and local regulations.
Short circuit protection
Danfoss recommends using the fuses and circuit breakers
listed in Table 3.8 to protect service personnel or other
equipment in case of an internal failure in the unit or
short-circuit on DC-link. The frequency converter provides
full short circuit protection in case of a short-circuit on the
motor.
Overcurrent protection
Provide overload protection to avoid overheating of the
cables in the installation. Overcurrent protection must
always be carried out according to local and national
regulations. Circuit breakers and fuses must be designed
for protection in a circuit capable of supplying a maximum
of 100000 Arms (symmetrical), 480 V maximum.
UL/Non UL compliance
Use the circuit breakers or fuses listed in Table 3.8, to
ensure compliance with UL or IEC 61800-5-1.
Circuit breakers must be designed for protection in a
circuit capable of supplying a maximum of 10000 Arms
(symmetrical), 480 V maximum.
NOTICE
In the event of malfunction, failure to follow the
protection recommendation may result in damage to the
frequency converter.
