2.  Installation 

2.1. Requirements 

The device should be mounted by a qualified installer, holding relevant permits and licenses (applicable and  required  for  

a  given  country)  for  230 V and  low-voltage  installations.  

 
The  device  shall  be  mounted  in  confined  spaces,  according  to  the  environment  class  II,  with  normal  air  humidity 

(RH=90% max. without condensation) and the temperature from -10 

°C to +40 °C.  

The  switch  shall  work  in  a  vertical  position  that  guarantees  sufficient  convectional  air-flow  through  ventilating  holes  of  the 
enclosure.  

 
Before installation, prepare a Switch'a load balance.  

 
The given value of 30 W per port is the maximum value referring to a single output. The total power consumption 

should  not  exceed  96  W.

  The  increased  demand  for  power  is  particularly  evident  in  the  case  of  cameras  with  heaters  or 

infrared illuminators - when launching these features, the power consumption increases rapidly, which may adversely affect the 
operation of the switch. As the device 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  (usually  through  assigning  an  appropriate  fuse  in  the  fuse-box).  The  electrical  system  shall  follow 
valid standards and regulations. 
 

2.2.  Installation procedure 

 

 

 

Before installation, cut off the voltage in the 230 V power-supply circuit. 

To switch power off, use an external switch, in which the distance between the contacts of all 

poles in the disconnection state is not less than 3mm. 

 

 

It is required to install an installation switch with a nominal current of  6 A in the power supply circuits  

outside the power supply unit.
