1. All terminals with the same name are connected together on the module. For
example, L1 can be connected to either terminal marked L1-15.
2. When daisy chaining the second L1-15 terminal to other RTBs, always connect the
daisy chain to the terminal directly connected to the supply wire, as shown in the
example above. Do not connect more than 2 wires to any single terminal.
3. If separate power sources are used, do not exceed the specified isolation voltage.

1. 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.
2. This wiring example uses a single voltage source.
3. If separate power sources are used, do not exceed the specified isolation voltag
e
4. Do not physically connect more than two wires to a single RTB terminal.

1. All terminals with the same name are connected together on the module. For
example, L1-0 can be connected to either terminal marked L1-0.
2. When you use the third L1-7 terminal to daisy chain to other RTBs, always connect
the daisy chain to the terminal directly connected to the supply wire, as shown in
the example above.
