Mounting
1. Fasten the DIN rail (TH 35-15 or TH 35-7.5 acc. IEC/EN 60715) as shown in Fig. I on the mounting plate, horizontal mounting position,
respect the minimum distance to other units (see Fig. I)
2. Snap on DIN rail as shown in Fig. II
1) Tilt the unit slightly upwards and fit the unit on the DIN rail
2) Lift it downward until it hits the stop
3) Press against the bottom front side for locking
Shake the unit slightly to check the locking
3. Remove the unit from the DIN rail as shown in Fig. III. Use a screwdriver for the unlocking.

Rate the lines for the maximum output current or provide a separate fuse protection. Fuse protection of the output side - see technical
data. We recommend choosing the cable cross section as large as possible in order to minimize voltage drops. Observe the polarity. The
buffer module is overload and no-load proof.

Operating state
Input voltage applied
Device in operation (input voltage applied or device is internally supplied by using energy stored
in capacitors)
Charging process (energy stored in capacitors > 30 and < 80 %)
Energy stored in capacitors > 80 % (while charging)
Energy stored in capacitors < 30 % (while discharging)
Capacitors discharged (load no longer supplied, only internal supply is maintained)
Overvoltage at internal capacitors, overcurrent at output, overvoltage at input terminals
Capacitors discharged or shut-down is activated
-- = not relevant
VI Characteristic curve of temperature
Normal application (up to 50 % buffer mode, 5 charging and discharging cycles in direct series)
Continuous charging and discharging in direct series. As this is not typical of a real application, this should be considered as
theoretical indication.
