1. Make wiring connections as described in the installation instructions
included with the specific module that mounts on your terminal base.
2. Connect +V and -V from the terminal base to the next using jumpers
or individual external wiring, if appropriate due to total module power
consumption.
ATTENTION
Do not use any unused terminals on the terminal base. Using
these them as supporting terminals can result in damage to the
module and/or unintended operation of your system.
Daisy-chaining

+V, -V
Wiring when total module current power is less than 8.5 W.
Combination
Wiring when total module current power is greater than 8.5 W.
41111
+V, -V 
<8.5 W
+V, -V 
<8.5 W
You can use the daisy
chain configuration if
the total module power
draw is <8.5 W.
Otherwise, power is
connected to individual
modules.
Other variations are possible depending upon individual module power.
