1.1 Safety
WARNING
HIGH VOLTAGE
Adjustable frequency drives contain high voltage when
connected to AC line power. Failure to perform instal-
lation, start-up, and maintenance by qualified personnel
could result in death or serious injury.
•Installation, start-up, and maintenance must be
performed by qualified personnel only.
WARNING
UNINTENDED START
When the adjustable frequency drive is connected to AC
line power, the motor may start at any time, causing risk
of death, serious injury, equipment, or property damage.
The motor can be started with an external switch, a
serial bus command, an input reference signal from the
LCP or LOP, or after a cleared fault condition.
1. Disconnect the adjustable frequency drive from
line power whenever personal safety consider-
ations make it necessary to avoid unintended
motor start.
2. Press [Off/Reset] on the LCP before
programming any parameters.
3. The adjustable frequency drive, motor, and any
driven equipment must be in operational
readiness when the adjustable frequency drive
is connected to AC line power.
WARNING
DISCHARGE TIME
The adjustable frequency drive contains DC link
capacitors that can remain charged even when the
adjustable frequency drive is not powered. Failure to
wait the specified 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 line power, permanent magnet
type motors, and remote DC link power
supplies, including battery backups, UPS, and
DC link connections to other adjustable
frequency drives.
3. Wait for the capacitors to discharge fully before
performing any service or repair work. The
duration of waiting time is specified in
Table 1.1.
Size Minimum waiting time (min)
M1, M2 and M3 4
M4 and M5 15
Table 1.1 Discharge Time
Leakage Current (>3.5 mA)
Follow national and local codes regarding protective
grounding of equipment with a leakage current > 3.5 mA.
Adjustable frequency drive technology implies high
frequency switching at high power. This generates a
leakage current in the ground connection. A fault current
in the adjustable frequency drive at the output power
terminals might contain a DC component that can charge
the filter capacitors and cause a transient ground current.
The ground leakage current depends on various system
configurations including RFI filtering, shielded motor
cables, and adjustable frequency drive power.

EN/IEC61800-5-1 (Power Drive System Product Standard)
requires special care if the leakage current exceeds 3.5 mA.
Grounding must be reinforced in one of the following
ways:
•Ground wire of at least 10 mm2.
•Two separate ground wires, both complying with
the dimensioning rules.
See EN 60364-5-54 § 543.7 for further information.
Using RCDs
Where residual current devices (RCDs), also known as
ground leakage circuit breakers (GLCBs), are used, comply
with the following:
1. Use RCDs of type B only which are capable of
detecting AC and DC currents.
2. Use RCDs with an inrush delay to prevent faults
due to transient ground currents.
3. Dimension RCDs according to the system configu-
ration and environmental considerations.
Motor Thermal Protection
Motor overload protection is possible by setting parameter
1-90 Motor Thermal Protection to [4] trip. For the North
American market: Implemented function provides class 20
motor overload protection, in accordance with NEC.
Installation at High Altitudes
For altitudes above 6,600 ft [2,000 m], contact Danfoss.
1.1.1 Safety Instructions
•Make sure the adjustable frequency drive is
properly grounded.
•Do not remove AC line input connections, motor
connections or other power connections while
the adjustable frequency drive is connected to
line power.
•Protect users against supply voltage.
•Protect the motor against overloading according
to national and local regulations.
•The ground leakage current exceeds 3.5 mA.
•The [Off/Reset] key is not a safety switch. It does
not disconnect the adjustable frequency drive
from line power.

1.2.3 Avoid Unintended Start
While the adjustable frequency drive is connected to line
power, the motor can be started/stopped using digital
commands, bus commands, references or via the LCP or
LOP.
•Disconnect the adjustable frequency drive from
line power whenever personal safety consider-
ations make it necessary to avoid unintended
start of any motors.
•To avoid unintended start, always press [Off/
Reset] before changing parameters.
Equipment containing electrical components
may not be disposed of together with domestic
waste.
It must be separately collected with electrical
and electronic waste according to local and
currently valid legislation.
1.3 Installation
1.3.1 Before Commencing Repair Work
1. Disconnect the FC 51 from line power (and
external DC supply if present.)
2. Wait for 4 min (M1, M2 and M3) and 15 min (M4
and M5) for discharge of the DC link. See
Table 1.1.
3. Disconnect DC bus terminals and brake terminals
(if present).
4. Remove motor cable.
1.3.2 Side-by-Side Installation
The adjustable frequency drive can be mounted side-by-
side for IP20 rating units and requires 4 in [100 mm]
clearance above and below for cooling. Refer to
chapter 1.7 Specifications for details on environmental
ratings of the adjustable frequency drive.

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-circuited and overcurrent-protected according to national/international regulations.
Short circuit protection
Danfoss recommends using the fuses mentioned in the following tables to protect service personnel or other equipment in
case of an internal failure in the unit or short-circuit on DC link. The adjustable frequency drive provides full short-circuit
protection in case of a short-circuit on the motor or brake output.
Overcurrent protection
Provide overload protection to avoid overheating of the cables in the installation. Overcurrent protection must always be
carried out according to national regulations.
Non-UL compliance
If UL/cUL is not to be complied with, Danfoss recommends using the fuses mentioned in Table 1.4, which ensures
compliance with EN50178/IEC61800-5-1:
In case of malfunction, not following the fuse recommendation may result in damage to the adjustable frequency drive and
the installation.

1.3.4 Connecting to Line Power and Motor
The adjustable frequency drive is designed to operate all
standard 3-phased asynchronous motors.
The adjustable frequency drive is designed to accept line
power/motor cables with a maximum cross-section of
4 mm2/10 AWG (M1, M2 and M3) and maximum cross-
section 16 mm2/6 AWG (M4 and M5).
•Use a shielded/armored motor cable to comply
with EMC emission specifications, and connect
this cable to both the decoupling plate and the
motor metal.
•Keep motor cable as short as possible to reduce
the noise level and leakage currents.
•For further details on mounting of the
decoupling plate, see VLT Micro FC 51 Decoupling
Mounting Plate Instructions.
•Also see EMC-compatible Installation in the
Design Guide.
1. Mount the ground wires to PE terminal.
2. Connect the motor to terminals U, V and W.
3. Mount line power supply to terminals L1/L, L2
and
L3/N (3-phase) or L1/L and L3/N (single-phase)
and tighten.
