Electrical Installation
5.2.8
EMC-compliant installation
With respect to the EMC regulation, frequency inverters cannot be operated as stand-
alone units. Regarding EMC, they can only be evaluated when they are integrated in a
drive system. Conformity is declared for a described, CE-typical drive system. These
operating instructions contain further information.
5.2.9
Installation altitudes above 1000 m asl
MOVIGEAR
®
drive units can be used at altitudes above 1000 m asl up to 4000 m asl
under the following conditions:
1)
• The nominal continuous power is reduced due to the reduced cooling above 1000 m
(see chapter "Technical data and dimension sheets").
• Above 2000 m asl, the air and creeping distances are only sufficient for overvoltage
class 2. If the installation calls for overvoltage class 3, you will have to install
additional external overvoltage protection to limit overvoltage peaks to 2.5 kV phase-
to-phase and phase-to-ground.
• If safe electrical disconnection is required, it must be implemented outside the device
at altitudes of 2,000 msl (safe electrical disconnection in accordance with EN 61800-
5-1).
• In installation altitudes between 2,000 m to 4,000 msl, the permitted rated power
supply voltages are reduced as follows:
– By 6 V per 100 m
5.2.10 Protection devices
• MOVIGEAR
®
drive units are equipped with integrated protection devices against
overload.
• Cable protection must be implemented using external overload devices.
• Observe the relevant standards concerning the cable cross section, voltage drop and
installation type.
WARNING
This drive system is not designed for operation on a public low voltage supply system
that supplies residential areas.
INFORMATION
• This is a product with restricted availability in accordance with IEC 61800-3. It may
cause EMC interference. In this case, it may be recommended for the operator to
carry out suitable measures.
• For detailed information on EMC compliant installation, refer to the publication
"Electromagnetic Compatibility in Drive Engineering" from SEW-EURODRIVE.
1) The maximum altitude is limited by creeping distances and flameproof components such as capacitors.
