1.1 Safety

1.1.1 Warnings

WARNING

High Voltage Warning

The voltage of the frequency converter is dangerous

whenever it is connected to mains. Incorrect installation of

the motor or frequency converter may cause damage to

the equipment, serious injury or death. Consequently, it is

essential to comply with the instructions in this manual as

well as local and national rules and safety regulations.

WARNING

Electrical Hazard

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 as stated in the table

below:

Voltage (V) Power range (kW) Min. waiting time

(minutes)

3 x 200 0.25 – 3.7 4

3 x 200 5.5 – 11 15

3 x 400 0.37 – 7.5 4

3 x 400 11 – 90 15

3 x 600 2.2 – 7.5 4

3 x 600 11 – 90 15

CAUTION

Leakage Current:

The earth leakage current from the frequency converter

exceeds 3.5 mA. According to IEC 61800-5-1 a reinforced

Protective Earth connection must be ensured by means of

a min. 10 mm² Cu or an additional PE wire - with the same

cable cross section as the Mains wiring - must be

terminated separately.

Residual Current Device:

This product can cause a DC current in the protective

conductor. Where a residual current device (RCD) is used

for extra protection, only an RCD of Type B (time delayed)

shall be used on the supply side of this product. See also

Danfoss Application Note on RCD, MN90GXYY.

Protective earthing of the frequency converter and the use

of RCDs must always follow national and local regulations.

Motor thermal protection:

Motor overload protection is possible by setting Parameter

1-90 Motor thermal protection to the value Electronic

Thermal Relay (ETR) trip.

WARNING

Installation at high altitudes

For altitudes above 2 km, please 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] key is not a safety switch. It does not

disconnect the frequency converter from mains.

1.2 Introduction

1.2.1 Available Literature

This quick guide contains the basic information necessary

for installing and running the frequency converter. If more

information is needed, literature can be found on the

enclosed cd or downloaded from:

http://www.danfoss.com/Products/Literature/Technical

+Documentation.htm

1.2.2 Approvals

1.2.3 IT Mains

CAUTION

IT Mains

Installation on isolated mains source, i.e. IT mains.

Max. supply voltage allowed when connected to mains:

440 V (3 x 380-480 V units).

On IP20 200-240 V 0.25-11 kW and 380-480 V IP20 0.37-22

kW, open the RFI switch by removing the screw on the

side of the frequency converter when at IT grid.

380-480 V.

1: EMC screw

130BC251.10

Illustration 1.2 IP54 400 V 0.75-18.5 kW

1: EMC screw

On all units, set par. 14-50 RFI filter to OFF when operating

in IT mains.

CAUTION

If reinserted, only use M3 x 12 screw.

1.2.4 Avoid Unintended Start

While the frequency converter is connected to mains, the

motor can be started/stopped using digital commands, bus

commands, references or via the LCP.

•Disconnect the frequency converter from mains

whenever personal safety considerations make it

necessary to avoid unintended start of any

motors.

•To avoid unintended start, always activate the

[OFF] key before changing parameters.

1.2.5 Disposal Instruction

Equipment containing electrical components

must 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 Starting Repair Work

1. Disconnect FC101 from mains (and external DC

1.3.5 Connecting to Mains and Motor

The frequency converter is designed to operate all

standard three-phased asynchronous motors. For

maximum cross-section on wires please see section

1.7 General Specifications.

•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, please see instruction

MI02QXYY

•Also see EMC-Correct Installation in the Design

Guide, MG18CXYY.

1. Mount the earth wires to earth terminal.

2. Connect motor to terminals U, V and W.

3. Mount mains supply to terminals L1, L2 and L3

and tighten.
