Unless otherwise specified in this manual, please follow these guidelines:

1. Shielded cable is recommended in electrically noisy environments.

2. You can use a local power supply for the reader. If so, don’t connect the 

power supply from the controller to the reader. The ground line of the 
local power supply must be connected to the power supply of the 
controller. 

3. The unit needs to be operated with a power source with limited power 

consumption according to EN 60950-1 (2001) paragraph 2.5.
Das Gerät ist mit einer Stromquelle mit begrenzter Leistung nach  
EN60950-1 (2001) Absatz 2.5 zu betreiben. Des Weiteren gilt die 

          EN 60950-1 (2001) nur in Europa und nicht in den USA!

 
     4. Use of a pull-up resistor may be required by some controllers. Consult 

     your controller manual.

     5. For tamper wiring, connect Pins 11 and 12 to a normally closed 

     supervised input, as shown in Figure 3.
