1.1 Purpose of the Manual
This manual is intended to provide detailed information for
the installation and start up of the frequency converter.
2 Installation provides requirements for mechanical and
electrical installation, including input, motor, control and
serial communications wiring and control terminal
functions. 3 Start Up and Functional Test provides detailed

1.2 Product Overview
A frequency converter is an electronic motor controller
that converts AC mains input into a variable AC waveform
output. The frequency and voltage of the output are
regulated to control the motor speed or torque. The
frequency converter can vary the speed of the motor in
response to system feedback, such as changing
temperature or pressure for controlling fan, compressor, or
pump motors. The frequency converter can also regulate
the motor by responding to remote commands from
external controllers.
In addition, the frequency converter monitors the system
and motor status, issues warnings or alarms for fault
conditions, starts and stops the motor, optimizes energy
efficiency, and offers many more control, monitoring, and
efficiency functions. Operation and monitoring functions
are available as status indications to an outside control
system or serial communication network.

2.4.1 Requirements
W
WARNING
EQUIPMENT HAZARD!
Rotating shafts and electrical equipment can be hazardous.
All electrical work must conform to national and local
electrical codes. It is strongly recommended that instal-
lation, start up, and maintenance be performed only by
trained and qualified personnel. Failure to follow these
guidelines could result in death or serious injury.
CAUTION
WIRING ISOLATION!
Run input power, motor wiring and control wiring in three
separate metallic conduits or use separated shielded cable
for high frequency noise isolation. Failure to isolate power,
motor and control wiring could result in less than
optimum frequency converter and associated equipment
performance.
For your safety, comply with the following requirements.
•
Electronic controls equipment is connected to
hazardous mains voltage. Extreme care should be
taken to protect against electrical hazards when
applying power to the unit.
•
Run motor cables from multiple frequency
converters separately. Induced voltage from
output motor cables run together can charge
equipment capacitors even with the equipment
turned off and locked out.
Overload and Equipment Protection
•
An electronically activated function within the
frequency converter provides overload protection
for the motor. The overload calculates the level of
increase to activate timing for the trip (controller
output stop) function. The higher the current
draw, the quicker the trip response. The overload
provides Class 20 motor protection. See
8 Warnings and Alarms for details on the trip
function.
•
All frequency converters must be provided with
short-circuit and over-current protection. Input
fusing is required to provide this protection, see
Illustration 2.6. If not factory supplied, fuses must
be provided by the installer as part of instal-
lationinstallation. See maximum fuse ratings in
10.1 Power-dependent Specifications.

Wire Type and Ratings
•
All wiring must comply with local and national
regulations regarding cross-section and ambient
temperature requirements.
•
Danfoss recommends that all power connections
be made with a minimum 75 rC rated copper
wire.
•
See 10.1 Power-dependent Specifications for
recommended wire sizes.
2.4.2 Earth (Grounding) Requirements
WARNING
GROUNDING HAZARD!
For operator safety, it is important to ground the
frequency converter properly in accordance with national
and local electrical codes as well as instructions contained
within this document. Ground currents are higher than 3.5
mA. Failure to ground the frequency converter properly
could result in death or serious injury.
NOTE
It is the responsibility of the user or certified electrical
installer to ensure correct grounding (earthing) of the
equipment in accordance with national and local electrical
codes and standards.
•
Follow all local and national electrical codes to
ground electrical equipment properly
•
Proper protective grounding for equipment with
ground currents higher than 3.5 mA must be
established, see 2.4.2.1 Leakage Current (>3.5 mA)
•
A dedicated ground wire is required for input
power, motor power and control wiring
•
Use the clamps provided with the equipment for
proper ground connections
Installation VLTpRefrigeration Drive FC 103 1.1-90 kW Operating Instructions
12 MG16E202 - VLT® is a registered Danfoss trademark
22
inverter.ru [phone]

•
•
Do not ground one frequency converter to
another in a “daisy chain” fashion
•
Keep the ground wire connections as short as
possible
•
Using high-strand wire to reduce electrical noise
is recommended
•
Follow motor manufacturer wiring requirements
2.4.2.1 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
