WARNING
While the unit is powered, a potentially lethal shock hazard exists inside the case. Do not open
the case while the unit is powered. Do not access the terminals while the unit is powered.
The 10260S actuator terminal connections for the field wiring are located behind the cover on the actuator
case as shown in Figure 2. Power and field wiring is brought into the actuator through two access holes
located on the side of the actuator case. The screw terminals for all customer connections are identified in
Table 3.
Figure 13 shows the location of the terminal connections on the actuator terminal blocks. Desciptions for
power input, input and output signal connections are given in Table 3.
