2.3.6  Connection Of Temperature Sensor Cables 

There are two 3-pin terminals on the connector board in rectifier shelf. These two 

terminals are J11 and J10 respectively. They are used to connect the temperature 

sensors. The locations of J11 and J10 are as shown in Figure 2-12. 

The user can connect the temperature sensor cables to J11 and J10. 

2.3.7  Connection With MODEM

MODEM connects with M500D monitoring module through connector board 

S6415X2: 

1. Connect telephone line to the “LINE” port of MODEM. 

2. Connect the 48V “POWER” terminal of MODEM with the J19 socket of connector 

board S6415X2. 

3. Connect “RS-232” (DB25 female) communication port of MODEM with the J12 or 

J18 terminal (DB9 male) of connector board S6415X2 using a communication 

cable.  

 Note 

When the cabinet has a front door, before connecting the RS232 terminal, pull out the 
S6415X2 board first, pass the RS232 terminal through the opening on the right side of the 
rectifier subrack and connect it with the J18 terminal on the S6415X2 board, then insert the 
S6415X2 board.
