Figure 5: Relay A through D installation 

 

2.  Refer to the following figure to connect and solder the supplied ribbon cable to the following relays: 

XFER relays (transfer relays); 26.5 GHz unterminated relays; MSPDT relays 

3.  For the A through D relays, secure the ribbon cable to the relay with the two supplied screws. 
4.  Using the following figure, install the relay in the mounting hole, and then secure it with the four screws 

removed in step 1. 

5.  Plug the ribbon connector into the appropriate circuit board connector (see previous figure). 
6.  Install the top cover, and then configure the system as covered in (see 

System configuration

 (on page 9)).
