Using this Quick Setup, you can carry out quick
and EMC-correct installation of the frequency
converter (Fig. 1) in five steps. (Fig. 1: *= Start/
stop). The Operating Instructions, which are also
enclosed, give other examples of installation and
describe all functions in detail.
Read the safety instructions on this page before
installing the unit.

Mechanical installation
VLT 2800 frequency converters allow side-by-
side installation on a wall. 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 fig. 2. Please note the difference in unit
voltages.
Retighten all four screws.
Fit the decoupling plate to the power cables and
the earth screw (terminal 95).

Carry out programming on the control panel.
Press the [QUICK MENU] key to enter the Quick
menu.
In this menu, parameters can be selected by
means of the [+] and [-] keys. The parameter
values can be changed by pressing [CHANGE
DATA].
Changes are programmed using the [+] and [-]
keys.
Finish the change of a parameter setting by
pressing [CHANGE DATA].
A change of parameter values is saved automa-
tically after a mains failure.
If the display shows three dots at the right, the
parameter value has more than three digits. In
order to see the value, activate [CHANGE DATA].

Connect mains to the mains terminals of the
frequency converter, i.e. 91, 92, 93 and the earth
connection to terminal 95 (Fig. 3).
Fit a screened/armoured cable from the motor to
the motor terminals of the frequency converter,
i.e. U, V, W (Fig. 3). The screen ends in a screen
connector.

Safety regulationsSafety regulations
Safety regulationsSafety regulations
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.
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 startWarning against unintended start
Warning against unintended startWarning against unintended start
Warning against unintended start
1. 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.
2. 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.
3. 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.
