During normal PSU operation, the BS technical output is cut from ground (-AUX). In case lf 230V AC power outage, 
it is connected to ground (-AUX) after a time set by Z1, Z2 pins. 
    - 

AW 

output indicating failure 

During normal PSU operation, the AW technical output is connected to ground. If a failure occurs, the output is cut 
from ground. 
6. During battery-assisted operation, it is possible to determine time necessary for battery disconnection by the  

Z3, Z4 

pins when the voltage at its terminals drops below 10V. 

7. On the 

CHARGE 

pins, determine the battery charging current: 

    Ibat = 0,4 A

  max. – jumper on  

    

Ibat = 0,9 A

 max. – jumper off (unacceptable

 for: AWZ110, AWZ224). 

8. Restore the 230V AC power and plug the line fuse protecting the primal circuit of the transformer. 
Check the LED indication for PSU power status. 

Output voltage of the PSU, without load: U = 13,8V DC.  
During battery charge, voltage can amount to U = 11 V÷13,8V DC 

9. Connect the battery in accordance with the markings:“+” red, „-„ black) 
Mount the battery with a 700x 8mm clamp, following the procedure according to Fig. 5 
 

- put the battery into the enclosure 

 

- lead the clamp through the left A hole  

 

- lead the clamp over the up side of the battery 

 

- lead the clamp through the B hole  

 

- lead the end of the clamp into the terminal hole 

 

- pull the clamp with force of 150N-200N 

 

- cut the jutting piece of the tape 

10. With the 

STOP

 button, initiate or finish a dynamic battery test. 

Deactivating the test turns out the PSU failure indication at the AW output, but it does not affect the protection 
system against complete battery discharge. 
11. Run the PSU test: check the LED and acoustic indication (Tab. 7), AW technical output; through: 

cutting off the 230V AC current:

 LED and acoustic indications – immediately; the BS technical output – 

after some time, determined by Z1, Z2 pins. 

battery disconnection:

 LED indication, acoustic indication and the AW technical output – after a battery 

test have been completed (approx. 10 min.) 
12. With the 

STOP

 button, initiate or finish a dynamic battery test. 

13. With the 

ZB 

pins, decide whether the acoustic indication stall be on (jumper on), or off (jumper off) 

14. Once the tests and operation control have been completed, the enclosure can be locked.
