3.2.1 Power supply unit circuit board SMP 20 (Fig. 2)

- Transformer terminal 

20V, 50Hz.

- Relay 

which can be programmed from the central  

  control unit.
- Four +12 V voltage outputs 

(+1, +3, +4, +6) each of  

  which is protected by a fuse (F2 to F5).  

 

- Output 

for mains supply indication (not fused).

- E-Bus connection to central control unit 

(B1-, B2, B3,  

  B4+). B4+ is protected by fuse F1.
- Pre-wired battery terminal 

is protected by fuse F6.

- Address key 

P

.

- LED 

fl ashes if the E-Bus communication is correct.

- LED 

for mains supply indication.

-  The adjustment of potentiometer 

,

must not be disturbed.
