5.2.6
EMC-compliant installation
INFORMATION
This drive system is not designed for operation on a public low voltage grid that sup-
plies residential areas.
This is a product with restricted availability (categories C1 to C4 according to
EN 61800-3). This product may cause EMC interference. In this case, it is recom-
mended that the user take suitable measures.
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.
5.2.7
Installation above 1000 m amsl
MOVIMOT
®
drives with mains voltages of 200 – 240 V or 380 – 500 V can also be
operated at an altitude of 1000 – 4000 m amsl. To do so, you must observe the follow-
ing basic conditions.
• At heights above 1000 m amsl, the nominal continuous power is reduced due to
reduced cooling: I
N
reduction by 1% per 100 m.
• At altitudes of 2000 – 4000 m amsl you must take limiting measures which reduce
the line side overvoltage from category III to category II for the entire system.
5.2.8
Protection devices
MOVIMOT
®
drives have integrated protection devices against overloads. External
overload devices are not necessary.
5.2.9
UL-compliant installation
Routing power terminals in the field
Note the following points for UL-compliant installation:
• Use only 60°/75°C copper conductors.
• The terminals' permitted tightening torque is 1.5 Nm (13.3 lb.in)
