■Quick Setup

■General warning

Using this Quick Setup, you can carry out quick and

EMC-correct installation of the frequency converter

in five steps. The Operating Instructions, which are

also enclosed, give other examples of installation

and describe all functions in detail.

Read the safety instructions on the next

page before installing the unit.

■Mechanical Installation

Frequency converters allow side-by-side installation.

Because of the need for cooling, there must be

10 cm free air passage above and below the

frequency converter. Drill holes in accordance with

the measurements given in section Mechanical

■Safety regulations

The voltage of the frequency converter

can be fatal whenever it is connected to

mains. Incorrect installation of the motor or

the frequency converter may lead to damage to the

equipment, serious personal injury or death.

Consequently, the provisions of this Quick Setup,

as well as national and local rules and safety

regulations, must be complied with.

Touching the electrical parts may be fatal, even

after the equipment has been disconnected from

mains: wait at least 4 min.

1. The mains supply to the frequency converter must

be disconnected if repair work is to be carried out.

2. The [STOP/RESET] key on the control panel of the

frequency converter does not disconnect the mains

supply and is thus not to be used as a safety switch.

MG.28.H2.02 -

AKD 2800

Quick

Setup

3. Correct protective earthing of the unit must be

established, the user must be protected against

supply voltage, and the motor must be protected

against overload in accordance with applicable

national and local regulations.

4. The earth leakage current is higher than 3.5 mA.

5. Protection against motor overload is not included

in the factory setting. If this function is required,

set parameter 128 Motor thermal protection to

data value ETR Trip or ETR Warning.

6. Check that the mains supply has been disconnected

before removing the motor and mains plugs.

■Warning against unintended start

The motor can be brought to a stop

by means of digital commands, bus

commands, references or local stop,

while the frequency converter is connected to

mains. If personal safety considerations make

it necessary to ensure that no unintended start

occurs, these stops are not sufficient.

While parameters are being programmed, the

motor may start. Consequently, the stop key

[STOP/RESET] must always be activated, following

which data can be modified.

A motor that has been stopped may start if faults

occur in the electronics of the frequency converter, or

if a temporary overload, a fault in the supply mains

or a fault in the motor connection ceases.

■High voltage warning

The voltage of the frequency converter

is dangerous whenever the converter is

connected to mains. Incorrect fitting 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.

■These rules concern your safety

1. The frequency converter must be disconnected

from the mains if repair work is to be carried

out. Check that the mains supply has been

disconnected and that the prescribed time has

passed before removing motor and mains plugs.

2. The [STOP/RESET] key on the control panel of

the frequency converter does not disconnect

the equipment from mains and is thus not to

be used as a safety switch.

3. The unit must be properly connected to the

earth, the user must be protected against the

supply voltage and the motor must be protected

against overloading pursuant to prevailing

national and local regulations.

4. The earth leakage currents are higher than 3.5 mA.

5. Protection against motor overload is not included

in the factory setting. If this function is required,

set parameter 128 Motor thermal protection to

data value ETR trip or data value ETR warning.Fo

the North American market: The ETR functions

provide overload protection of the motor, class

20, in accordance with NEC.

6. Do not remove the plugs for the motor - and mains

supply while the frequency converter is connected

to mains. Check that the mains supply has been

disconnected and that the prescribed time has

passed before removing motor and mains plugs.

7. Note that the frequency converter has more voltage

inputs than L1, L2 and L3 when the DC bus

terminals are used. Check that all voltage inputs

are disconnected and that the prescribed time has

passed before repair work is commenced.

■Warning against unintended start

1. The motor can be brought to a stop by means

of digital commands, bus commands, references

or a local stop, while the frequency converter

is connected to mains. If personal safety

considerations make it necessary to ensure

that no unintended start occurs, these stop

functions are not sufficient.

2. While parameters are being changed, the

motor may start. Consequently, the stop key

[STOP/RESET] must always be activated, following

which data can be modified.

3. A motor that has been stopped may start if faults

occur in the electronics of the frequency converter,

or if a temporary overload or a fault in the supply

mains or the motor connection ceases.

195NA300.10

Warning:

It can be extremely dangerous to touch the electrical parts

even when the mains supply has been disconnected.

Also ensure that other voltage inputs are disconnected

from load sharing through the DC bus.

Wait at least 4 minutes after the input power has been

removed before servicing the drive.

MG.28.H2.02 - 9

AKD 2800

■Control unit

On the front of the frequency converter there

is a control panel.

The control panel is divided into four function groups:

1. Six-digit LED display.

2. Keys for changing parameters and shifting

display function.

3. Indicator lamps.

4. Keys for local operation.

All displays of data are in the form of a six-digit LED

display capable of showing one item of operating

data continuously during normal operation. As a

supplement to the display, there are three indicator

lamps for indication of mains connection (ON),

warning (WARNING) and alarm (ALARM). Most of

the frequency converter’s parameter Setups can be

changed immediately via the control panel, unless

this function has been programmed as Locked [1]

via parameter 018 Lock for data changes.

■Control keys

[QUICK MENU] allows access to the parameters

used for the Quick menu.

The[QUICKMENU]keyisalsousedifachangetoa

parameter value is not to be implemented.
