INSTALLATION AND WIRING

The DAMF-5 is 96 x 96 DIN size front panel mounted. After fixing it together with all related items, 
commence   wiring   by  referring   to   diagram   5.   If  possible,   mark   the   wires   according   to   the   terminal 
numbers. This allows for easier trouble shooting. Some of the terminations will not be required as the unit 
allows for various possibilities. Use a 6A fuse or  

MCB

  (Miniature Circuit Breaker) for the DAMF-5 

auxiliary supply to protect against accidental shorting. A separate 20A fuse or 

MCB

 for fuel solenoid and 

starter supply. Note that the 

GRR

 relay coil must be 240VAC and the supply taken from incoming side of 

main 

MCCB

 (Molded Case Circuit Breaker). Only one 

R1

 relay is use, for either Energized Stop or Fuel 

Solenoid. So, connect to either T02 or T03, which ever suit the gen-set.
