3. Installation
The description of installation in this chapter complies
with the EMC standards and the Machine Directive.
Select cable type and screening according to the EMC
requirements valid for the environment where the VSD
is installed.
3.1 Before installation
Read the following checklist and think through your
application before installation.
• External or internal control.
• Long motor cables (>100m), refer to section Long
motor cables.
• Motors in parallel, refer to menu [213].
• Functions.
• Suitable VSD size in proportion to the motor/appli-
cation.
• Mount separately supplied option boards according
to the instructions in the appropriate option manual.
If the VSD is temporarily stored before being connected,
please check the technical data for environmental con-
ditions. If the VSD is moved from a cold storage room to
the room where it is to be installed, condensation can
form on it. Allow the VSD to become fully acclimatised
and wait until any visible condensation has evaporated
before connecting the mains voltage.

0003 to 0073
3.2.1 Mains cables
Dimension the mains and motor cables according to
local regulations. The cable must be able to carry the
VSD load current.
Recommendations for selecting mains
cables
• To fulfil EMC purposes it is not necessary to use
screened mains cables.
• Use heat-resistant cables, +60°C or higher.
• Dimension the cables and fuses in accordance with
local regulations and the nominal current of the
motor. See table 49, page 165.
• The litz ground connection see fig. 23, is only neces-
sary if the mounting plate is painted. All the variable
speed drives have an unpainted back side and are
therefore suitable for mounting on an unpainted
mounting plate.
Connect the mains cables according to fig. 20 or 21.
The VSD has as standard a built-in RFI mains filter that
complies with category C3 which suits the Second Envi-
ronment standard.
