Installation above 1000 m above sea level

MOVIMOT^® drives can also be operated with line voltages of 200 – 240 V or 380 – 500 V at an altitude of 1000 – 3800 m above sea level. Therefore, observe the following basic conditions.

• At heights above 1000 m above sea level, the nominal continuous power is reduced due to reduced cooling: I_N reduction by 1% per 100 m.
• At altitudes of 2000 to 3800 m above mean sea level, you must take limiting measures which reduce the line side overvoltage from category III to category II for the entire system.
