General Security Notes 

The  oxygen  sensor  O2S  is  an  electronic  unit  for  the 
measurement  of  the  concentration  of  dissolved  oxygen  in 
water and must be used in combination with SENECT control 
units.  

Since  it  is an  electronic product  the  common  prerequisites 
for  a  safe  instrument  usage  must  be  fulfilled.  The 

corresponding  control  unit  must  be  operatated 
with 230 V AC (~50 Hz). Ensure that all cables are 
installed safely so that no obstacles for persons are 

built and all. Mount all cables and electric devices 
protected  against  direct  environmental  impacts 
like  overheating  by  direct  sunlight  and  water. 
Even if the products are protected against spray 

water,  the  product´s  lifetime  will  be  elongated,  if  it  is 
mounted on a protected place. The oxygen sensor O2S uses 
24 V DC supply voltage which is therefore not of danger for 
persons. 

For  many  applications  a  ground  fault  circuit  interruper 
(interrupting  current  <=  30  mA)  is  required  by  law.  Inform 
yourself about the valid legislation.
