• Do not use the line contactor for jog mode, but only for switching the inverter on
and off.
• Observe a minimum switch-off time of 2 s for the line contactor.

drives with mains voltages of 200 – 240V or 380 – 500V can also be op-
erated at an altitude of 1000 – 4000m amsl. To do so, you must observe the following
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.
