Plug connectors
All MOVIFIT

plug connectors are illustrated in these operating instructions with view
on the contact end.
5.3.9
Protection devices
MOVIFIT
®
drives have integrated protection devices against overloads. External over-
load devices are not necessary.
5.3.10
Installation altitude higher than 1000 m above sea level
MOVIFIT
®
units with supply voltages of 380 to 500 V can be used at altitudes above
1000 up to 4000 m above sea level. To do so, you must observe the following basic
conditions.
• At heights above 1000 m above sea level, the nominal continuous power is re-
duced due to reduced cooling: I
N
reduction by 1% per 100 m.
• At altitudes of 2000 to 4000 m above sea level you must take limiting measures
which reduce the line side overvoltage from category III to category II for the entire
system.
