Power Supply Connections
Figure 3.20 illustrates typical connections from main power supply.
Multiple Power Supplies
Cut JP1 and JP2 on ICM-4RK when supplying 24V power from two separate sources to the 
ICM-4RK. ICM-4RK circuits 1-2 will receive their power from J5; ICM-4RK circuits 3-4 will 
receive their power from J6.
Cut JP1 and JP2 on ICE-4 when supplying power from separate sources to expander circuits 5-8.  
ICM-4RK circuits 5-6 will receive power from J5 on the ICE-4 and ICM-4RK circuits 7-8 will 
receive power from J6 on the ICE-4. 
See Figure 3.21 for jumper locations.
