current. 

2.2.3  For  restricted  current  protection mode  switch  on  the  power  ON/OFF 

switch  7,  adjust  controls  3  anti-clockwise  to  the  minimum  position,  adjust 

controls 4 clockwise to set the desired output voltage level and then connect 

the load to the output terminals 5 & 6 Adjust controls 3 clockwise to set the 

output current at the desired level for restricted current protection. 

 

  3.    ATTENTION: 

3.1  In  the  event  of  a  short  circuit  at  the  output  the  current  will  limit  at  the 

value set by the current controls, however the unit should be turned off and 

the short circuit removed before continuing use. 

 

3.2 The mains power must be switched off before servicing and servicing 

should be referred to a qualified person.
