5.4.3 GPRS module installation 
The GPRS module is optional, and currently is supported only by  BPD004TNAC and 
BPD2K2–5K5TRAC(S).  If  a  GPRS  module  is  required,  connect  it  to  the  "GPRS" 
interface,  see  Figure  2.2  (b),  of  the  inverter. Figure  5.17  shows  the  connection.  For 
details about how to use the GPRS module, see the user manual delivered with it.
