Installation
Disconnect the MOVITRAC
®
LT from the supply system before starting to work. Ob-
serve the corresponding operating instructions.
WARNING
Danger of electric shock. Dangerous voltage levels may still be present inside the
device and at the terminals up to 10 minutes after disconnection from the power
supply.
Severe or fatal injuries.
•
Before removing the power supply cable, disconnect MOVITRAC
®
LT from the
power supply and wait at least 10 minutes.
•
Install one line choke just before each frequency inverter.
•
As an alternative, you can also use a shared line choke for the entire control cab-
inet. The common line choke is selected on the basis of the total current of all fre-
quency inverters.
The voltage supply is connected to the choke. Connect the protective earth (PE) of the
supply system to the choke.
