3 INITIAL OPERATION
The unit is put into operation through switch-on of the DC supply by means of the ‘IV’ terminal.
NOTE
For units built into systems in which overvoltages are applied for testing (e.g. in accordance with EN60204-1
/ VDE0113 part 1 19.4 Voltage testing) the unit must be disconnected from the test apparatus before the
voltage is applied.
(Original text EN60204-1 : Parts not designed for this test voltage must be disconnected during testing.)

LED- Anzeige
Operation Green LED lights up if system voltage is available.
IV o.k. Green LED lights up if external supply is available.
Uc > Green LED lights up if capacitor energy is > 80%.
LED- Anzeige
Green LED goes out if:
Capacitor energy is 30%
LED blinks slowly
(0,8Hz):
During charging until
80% of total capacitor
energy has been reached
LED blinks rapidly (3,2
Hz):
If capacitor is completely
discharged
Error Red LED lights up if: - overvoltage on the internal capacitor
- over- or undervoltage on the IV terminal
- output overvoltage
