1. All terminals with the same name are connected together on the module. For
example, DC (-) can be connected to either terminal marked GND-15.
2. When you use the second GND-15 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.
3. If separate power sources are used, do not exceed the specified isolation voltage.

GENERAL NOTES:
1. We recommend you use Belden M 8761 cable where shielded cables are shown.
2. Do not connect more than two wires to any single terminal.
CE REQUIREMENT NOTES:
1. DC power wire and I/O wire should not exceed 10m (30ft) in length.
2. The 0.01

1. All terminals with the same name are connected together on the module. For
example, L2 can be connected to either terminal marked L2-15.
2. When you use the second L2-15 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.
3. If separate power sources are used, do not exceed the specified isolation voltage.
