2. An EMC plan for preventing disturbances is drawn up for the installation. A template
is available in Technical guide No. 3 EMC compliant installation and configuration
for a power drive system (3AFE61348280 (English)).
3. The motor and control cables are selected as specified in this manual. For the best
EMC performance, the EMC recommendations are obeyed.
4. The drive is installed according to the instructions given in this manual.
WARNING!
Do not install a drive with the internal EMC filter connected to an earthing system
that the EMC filter is not suitable for (for example, an IT system). The supply
network becomes connected to ground potential through the internal EMC filter
capacitors, which can cause danger or damage to the drive.
WARNING!
To prevent radio-frequency interference, do not use a category C4 drive on a
low-voltage public network that supplies domestic premises.

WARNING!
Operation of this drive requires detailed installation and operation instructions
provided in the hardware and software manuals. The manuals are provided in
electronic format in the drive package or on the Internet. Keep the manuals with
the drive at all times. Hard copies of the manuals can be ordered through the
manufacturer.
• Make sure that the drive type designation label includes the applicable marking.
• DANGER - Risk of electric shock. After disconnecting the input power, always
wait for 5 minutes to let the intermediate circuit capacitors discharge before you
start working on the drive, motor or motor cable.
• The drive is to be used in a heated, indoor controlled environment. The drive must
be installed in clean air according to the enclosure classification. Cooling air must
be clean, free from corrosive materials and electrically conductive dust.
• The maximum surrounding air temperature is 50 °C (122 °F) at rated output current.
The output current is derated for 50 … 60 °C (122 … 140 °F) in drives with frame
size R1…R4.
• The drive is suitable for use in a circuit capable of delivering not more than
100000 rms symmetrical amperes, 480 V maximum (480 V drive types) when
protected by the UL fuses given elsewhere in this chapter. The ampere rating is
based on tests done according to the appropriate UL standard.
