Disconnecting the Dynamic Energy Storage Unit
• As long as the Dynamic Energy Storage Unit (with or without extension modules)
is charged with energy, it may not be disconnected from the DC link. The flashing
indicator LED on the top of the housing shows the state.
• To exclude any fault with the indicator LED, it is vital that you have seen it flashing
before it extinguishes. Only then can you be sure that it is safe to work on the
Dynamic Energy Storage Unit.
There is a risk of damage.
Discharging using the discharge bridge supplied can destroy
the Dynamic Energy Storage Unit.
Make sure that the effective resistance in the overall system

> 22 Ohm when discharging using the accompanying dis-
charge bridge.
