The company has a policy of continuous product development and improvement and we therefore 

reserve  the right to vary any information quoted without prior notice. 

 

The TPR sub-rack should be placed as near as possible the BTS or the RF repeater. 

The sub-rack location should be easy to reach by the users in order to allow alarm 
monitoring.

WARNING! do not close the air circulation subrack grids (top and bottom) with 

panels or obstacles.

If the subrack mounting location does not have a good air circulation, leave at 

least one unit (1HE) free between subracks.  

 
 

 

 
The connection to the mains has to be carried out following all the necessary 
precautions, including the following: 
•  in accordance with diligence rules (ex. CEI rules, IEC rules, etc.); 

•  in accordance with the rules for the safety against direct or indirect contacts; 

•  in accordance with the rules for the safety against over current (short circuit, 

overloading); 

•  in accordance with the rules for the safety against the over tension; 

•  the connection is to be carried out by properly trained technicians.

Universal mains  

Universal main (85-264VAC, 50/60Hz) apply to TPR912 model only. Mains 
connector is placed on the back panel (see Fig. 26  mains connector)

The TPR912 model has an internal AC/DC converter. With 220VAC power supply 
the efficiency is 75%. Each TFA has a power consumption of 12W, therefore a fully 
equipped configuration (6 TFLs) requires (12W x 6) / 0.75 = 96W. 

This formula is helpful in verifying the overall power consumption.
