Fig. 4. Electrical diagram of OC outputs.
3.3. Technical outputs
– relay.
If the OC type outputs are not sufficient to control the unit, it is possible to use the AWZ639relay module
changing technical outputs of the OC type to relay type.

3.4. Standby time.
Battery-assisted operating depends on battery capacity, charging level and load current. To maintain an
appropriate standby time, current drawn from the PSU in battery mode should be limited:

3.5. Battery charging time.
The PSU has a battery circuit charged with direct current. The current selection is done with use of the I
BAT
jumpers. The table below shows how long does ittake to charge a (fully discharged) batteryup to min. 80% of its nominal
capacity.
