2. Installation. 

 

2.1 Requirements. 

The buffer PSU is to be mounted by a qualified installer, holding relevant permits and licenses (applicable 

and  required  for  a  given  country)  for  230V  AC  interference  and  low-voltage  installations.  The  unit  should  be 
mounted  in  confined  spaces,  in  accordance  with  the  2nd  environmental  class,  with  normal  relative  humidity 
(RH=90% maximum, without condensation) and temperature from -

10°C to +40°C. The PSU shall work in a vertical 

position that guarantees sufficient convectional air-flow through ventilating holes of the enclosure.  

 

                          The power supply load balance should be done before installation:   

                         1.   Output current 16x0,8A + 5A re 2A battery charging

*

 

                         2.   Output current 16x0,7A + 5A re 4A battery charging

                                         3.   Output current 16x0,4A + 5A re 8A battery charging

 
                                  Total current of the rec battery 20A

*

 

max. 

 

As the PSU is designed for a continuous operation and is not equipped with a power-switch, therefore an 

appropriate  overload  protection  shall  be  guaranteed  in  the  power  supply  circuit.  Moreover,  the  user  shall  be 
informed about the method of unplugging (most frequently through separating and assigning an appropriate fuse in 
the fuse-box). The electrical system shall follow valid standards and regulations.  

 

2.2 Installation procedure. 

 

1. Before installation, make sure that the voltage in the 230V power-supply circuit is cut off. 

2. Mount the PSU in a selected location and connect the wires. 
3.  Connect  the  power  cables  (~230V  AC)  to  L-N  terminals  of  the  PSU.  Connect  the  ground  wire  to  the  terminal 

marked  by  the  earth  symbol 

– “

” on the plate. Use a three-core cable (with a  yellow and green  PE protection 

wire)  to  make  the  connection.  Lead  the  cables  to  the  appropriate  terminals  of  the  connection  board  through  the 
bushing.  

 

The shock protection circuit shall be performed with a particular care, i.e. the yellow and green 
wire  coat  of  the  power  cable  shall  stick  to  one  side  of  the  terminal 

marked  with  the  ‘

’  earth 

symbol in the PSU  enclosure.  Operation of the power supply without a properly made and fully 
operational  shock  protection  circuit  is  UNACCEPTABLE!  It  can  result  in  device  damage  or  an 
electric shock

.  

 

 
4. Connect the power supply of the DVR (by default, the device is equipped with a cable terminated with the DC 2.1 
/ 5.5 plug). 
5. Connect the camera cables to the 

AUX1…AUX16

 connectors of the LB8 modules. 

6. Connect the power (~230V). 
7. Check the PSU output voltage: 
- the PSU voltage without load should amount to U=13,8V DC.  
8. Connect the battery (mind the colours):   
- battery output (+):  BAT+ cable / red, 
- battery output (-):  BAT 

– cable / GND / black. 

9. Check the PSU operation indicator: green LED on the power supply module. 
10. After installing and checking proper working, the enclosure can be closed.
