4. Connect the DC(—) wire from the external SA DC power 
supply to the first SA(—) terminal.
5. Connect a wire from an Earth Ground location to the first 
Ground ( )
 on the RTB. The Earth Ground location can 
be the external SA power supply, the DIN rail, or other Earth 
Ground location.
Connect SA AC Power
Before you connect an external DC power source to the SA power 
RTB, make sure that the SA power source is adequately sized.
1. Verify that the SA power source is not powered on.
2. Strip insulation from the wires that you connect to the RTB.
3. Connect the L1/AC(+) wire from the external SA AC power 
source to the first SA(+) terminal.
4. Connect the L2/N/AC(—) wire from the external SA AC 
power source to the first SA(—) terminal.
RTB Type Action
Screw
1. Insert the wire into the terminal.
2. Turn the screwdriver to close the terminal on the wire. Torque the 
screw to 0.4 N•m (3.5 lb•in).
Spring
Push the wire into the terminal. 
If necessary, you can crimp a wire ferrule on the wire and insert it.

TIP
This  symbol denotes an Earth Ground terminal that provides a low 
impedance path between electrical circuits and earth for functional 
purposes and provides noise immunity improvement. This connection 
must be made for functional purposes.

WARNING: If you connect or disconnect wiring while the field-
side power is on, an electrical arc can occur. This could cause an 
explosion in hazardous location installations. Be sure that power is 
removed or the area is nonhazardous before proceeding.
