1.3.10 Installing the option cards
The option cards should ideally be installed after the installation of the inverter and before it is wired. Check that
the red LED for the display of the capacitor charge is off. Measure the voltage of the DC bus in accordance with
the procedures described, see "Position of the LED status indicator of the capacitor charge" on page 69
The option cards are installed behind the front panel of the inverter. If the inverter is equipped with a graphic display
terminal, remove it and then remove the front control panel as shown below.

release latch and pull to release the

remove it.
