NOTICE 

 

Please read instruction manual before usage 

 

 

Installation of MAM

8** can be performed only by professional technicians 

 

 

Assembling  position  shall  be  considered  carefully  during  mechanical  installation  in  order  to  ensure 

good heat dissipation and reduce electromagnetism interferences 

 

 

Wiring shall be performed respectively according to regulations for heavy and weak current to reduce 

electromagnetism interferences 

 

 

Surge absorber must be communicated with inductive load such as AC contactor of output control of 

relay 

 

 

Output wiring shall be inspected carefully before switch up 

 

 

Earthing terminal of this body part shall be earthed correctly (the third type of earthing) to increase 

product’s capacity of resisting signal noise. 

 

 

Motor’s rated current (current for stopping instrument automatically) shall be set according to rated 

current  indicated  on  motor’s  name  plate 

×

  overload  current    multiplication  factor  of                                               

motor/ 1.2
