5.1.1    The Controller is connected to the battery  d irectly, wrong connect the poles doesn t destroy 

the compressor and controller, but the compressor d o not work; 

5.1.2    The fuse must be connected  in the + cable to  protect controller, which close to the power 

supply, 15A fuse for 12VDC and 7.5A fuse for the 24 VDC are recommended; 

5.1.3    If a main switch is used, it should be rated  to current of min. 20A; 

5.1.4    To prevent voltage dropping, please avoid ex tra junction in the power supply system. 

5.1.5    A  Light  Emitting  Diode(LED)  for  compressor  o peration  monitoring  can  be  connected  

between the ter and D . 

Operational errors will cause the LED  to  flash a  nu mber of times.  The number of flashes 

depends on what kind of operational error was recor ded. Each flash will last 1/4 second and 

each error will repeat every 4 seconds. Operational  errors show by Table 5, please see it in 

page 6. 

5.1.6    If a cooling fan is used. It must be connect ed

    to electronic unit ter and F, only use 

12VDC fan , no matter what power supply you are usi ng; 

5.1.7    A Thermostat is connected between the termin al C and T of the electronic unit. It will start 

or stop the running of compressor automatically; 

5.1.8    A Resistor can be connected between terminal  C and T, it allows you to adjust the speed of 

the compressor, the  relationship  between the resist or and the compressor  speed shown  by  

Table 3; please see it in page 3. 

5.1.9    To  ensure  sufficient  battery  power  for  co mpr essor  and  avoid  permanent  damage  to  the  

battery  because  heavy  discharge.  A  battery   protecti on  resistor  is  connected  between  

terminal C and P, the different resistor will get t he different voltage protection, the details is 

showed by Diagram 4;
