1.1 Safety
1.1.1 Warnings
WARNING
HIGH VOLTAGE!
Frequency converters contain high voltage when
connected to AC mains input power. Installation, start up,
and maintenance should be performed by qualified
personnel only. Failure to perform installation, start up, and
maintenance by qualified personnel could result in death
or serious injury.
High Voltage
Frequency converts are connected to hazardous mains
voltages. Extreme care should be taken to protect against
shock. Only trained personnel familiar with electronic
equipment should install, start, or maintain this equipment.
Touching the electrical parts may be fatal - even after the
equipment has been disconnected from mains. Also make
sure that other voltage inputs have been disconnected
(linkage of DC intermediate circuit). Be aware that there
may be high voltage on the DC link even when the LEDs
are turned off. Before touching any potentially live parts of
the frequency converter, wait at least 4 min for all M1, M2
and M3 sizes. Wait at least 15 min for all M4 and M5 sizes.
WARNING
UNINTENDED START!
When the frequency converter is connected to AC mains,
the motor may start at any time. The frequency converter,
motor, and any driven equipment must be in operational
readiness. Failure to be in operational readiness when the
frequency converter is connected to AC mains could result
in death, serious injury, equipment, or property damage.
Unintended Start
When the frequency converter is connected to the AC
mains, the motor may be started by means of an external
switch, a serial bus command, an input reference signal, or
a cleared fault condition. Use appropriate cautions to
guard against an unintended start.
Leakage Current (>3.5 mA)
Follow national and local codes regarding protective
earthing of equipment with a leakage current > 3,5 mA.
frequency converter technology implies high frequency
switching at high power. This will generate a leakage
current in the earth connection. A fault current in the
frequency converter at the output power terminals might
contain a DC component which can charge the filter
capacitors and cause a transient earth current. The earth
leakage current depends on various system configurations
including RFI filtering, screened motor cables, and
frequency converter power.
EN/IEC61800-5-1 (Power Drive System Product Standard)
requires special care if the leakage current exceeds 3,5 mA.
Earth grounding must be reinforced in one of the
following ways:
•
Earth ground wire of at least 10 mm2.
•
Two separate earth 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 earth
leakage circuit breakers (ELCBs), are used, comply with the
following:
Use RCDs of type B only which are capable of
detecting AC and DC currents.
Use RCDs with an inrush delay to prevent faults
due to transient earth currents.
Dimension RCDs according to the system configuration and environmental considerations.
Motor Thermal Protection
Motor overload protection is possible by setting Parameter
1-90 Motor thermal protection to the value ETR trip. For
the North American market: Implemented ETR function
provide class 20 motor overload protection, in accordance
with NEC.
Installation at High Altitudes
For altitudes above 2 km, contact Danfoss regarding PELV.
1.1.2
Safety Instructions
•
Make sure the frequency converter is properly
connected to earth.
•
Do not remove mains connections, motor
connections or other power connections while
the frequency converter is connected to power.
•
Protect users against supply voltage.
•
Protect the motor against overloading according
to national and local regulations.
•
The earth leakage current exceeds 3.5 mA.
•
The [Off/Reset] key is not a safety switch. It does
not disconnect the frequency converter from
mains.

1.3.4 Fuses
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 frequency converter 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.
Fuses must be designed for protection in a circuit capable
of supplying a maximum of 100,000 A
rms
(symmetrical),
480 V maximum.
Non UL compliance
If UL/cUL is not to be complied with, Danfoss recommends
using the fuses mentioned in Table 1.6, which ensures
compliance with EN50178/IEC61800-5-1:
In case of malfunction, not following the fuse recommendation may result in damage to the frequency converter
and the installation.

1.3.5 Connecting to Mains and Motor
The frequency converter is designed to operate all
standard three-phased asynchronous motors.
The frequency converter is designed to accept mains/
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/armoured 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 Instruction MI02B.
•
Also see EMC-Correct Installation in Design Guide
MG02K.
1. Mount the earth wires to earth terminal.
2. Connect motor to terminals U, V and W.
3. Mount mains supply to terminals L1/L, L2 and
L3/N (3-phase) or L1/L and L3/N (single-phase)
and tighten.
