1.1 Safety
1.1.1 Warnings
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:
Touching the electrical parts may be fatal - even after the equipment has been dis-
connected from mains.Also make sure that other voltage inputs have been discon-
nected (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 minutes.
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. 10mm² Cu or an addtional PE wire - with the same cable cross
section as the Mains wiring - must be terminated separately.
To increase safety, install an RCD
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 de-
layed) shall be used on the supply side of this product. See also Danfoss Application
Note on RCD, MN.90.GX.YY.
Protective earthing of the frequency converter and the use of RCDs must always
follow national and local regulations.
Motor Thermal Protection:
Protection against Motor overload is not included in the factory setting. If this func-
tion is required, set par. 128
Motor Thermal Protection to data value ETR trip or data
value
ETR warning . For the North American market: The ETR functions provide
overload protection of the motor, class 20, in accordance with NEC.
Installation in high altitudes:
For altitudes above 2 km, please contact Danfoss regarding PELV.

1.1.2 Safety Instructions
• 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 the prescribed time
has passed before removing motor and mains plugs.
• Make sure the frequency converter is properly connected to earth.
• Protect users against supply voltage.
• Protect the motor against overloading according to national and local regulations.
• The earth leakage current exceeds 3.5 mA. For ELCB types, please see application note
MN.90.GX.YY.
• The [STOP/RESET] key on the control panel of the frequency converter does not dis-
connect the equipment from mains and is thus not to be used as a safety switch.
• Note that the frequency converter has more voltage inputs than L1, L2 and L3 when DC
bus terminals are used. Check that all voltage inputs are disconnected and that the pre-
scribed time has passed before repair work is commenced.
1.1.3 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 per-
sonal safety considerations make it necessary to ensure that no unintended start oc-
curs, 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 con-
nection ceases.
1.1.4 Use on Isolated Mains
See section RFI Switch in the operating instructions regarding use on isolated mains.
It is important to follow the recommendations regarding installation on IT-mains, since sufficient
protection of the complete installation must be observed. Not taking care using relevant moni-
toring devices for IT-mains may result in damage.

1.2.3 Approvals
1.2.4 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 Mechanical Installation
VLT 2800 frequency converters allow side-by-side installation on a wall in any position as the units
do not require ventilation on the side. Because of the need for cooling, there must be 10 cm free
air passage above and below the frequency converter.
All units with enclosure IP 20 must be integrated in cabinets and panels. IP 20 is not suitable for
remote mounting. In some countries, e.g. in the USA, units with enclosure NEMA 1 are approved
for remote mounting.

NB!
With the IP 21 solution all units require a minimum of 100 mm air on each side. This
means that side-by-side mounting is NOT allowed.

400-Volt units with RFI-filters may not be connected to mains supplies in which the
voltage between phase and earth is more than 300 Volts. Please note that for the
IT mains and the delta earth the mains voltage can exceed 300 Volts between phase
and earth. Units with type code R5 (IT mains) can be connected to mains supplies
with up to 400 V between phase and earth.
