Securing the wires/cabling will prevent 
breakage and ensure strong signals to and

The following is recommended: 
1.  The open bracket to the right of the 
actuator terminal strip is the strain 
relief for the customer provided control 
wires. 
2.  Secure the wires to the actuator 
bracket with a cable tie as shown in
