Connection sequence and label 
To ensure the power supply for the door lock connected to J6-
1 and J6-2, an external power supply is needed. Depending on 
the voltage needed for the door lock, a DC power supply of 
12/24 V must be connected to J2-1 (0 V) and J2-2 (+12/24 V).  
Depending on the settings of jumper J6, the OC output 
connected at J8 will also use this external power. The 
connection is protected by F2 (630 mA).

If the input is activated, relays RL3 will switch the voltage on 
J8-4 (voltage depending on setting J16, table 11) to J8-5.

Fuse F1 will protect the bus +12 V if this power supply is used 
for external connections (J9-6 / J8-4). 
The status of the door lock relay and the auxiliary output relay 
can be monitored by LEDs (table 14).
