1. All terminals with the same name are connected together on the module.
For example, DC COM can be connected to either terminal marked RTN OUT-1.
2. When you daisy chain from a group to another RTB, always connect the daisy
chain to the terminal directly connected to the supply wire, as shown above.
3. This wiring example shows a single voltage source.
4. If separate power sources are used, do not exceed the specified isolation voltage.
