Removing the Terminal Block
Remove the terminal block by turning the slotted terminal block release screws
counterclockwise. The screws are attached to the terminal block, so the block
will follow as the screws are turned out.
Input and Output Connections
Input and output wiring terminals are shown in the figure below. Each terminal
accepts two #14 AWG wires. Tighten screws only tight enough to immobilize the
wire. The torque applied to the screw should not exceed 0.9 Nm (8 in-lb).
Encoder Wiring
Differential encoders provide the best immunity to electrical noise. We
recommend, whenever possible, to use differential encoders.
The wiring diagrams on the following pages are provided to support the
Allen-Bradley encoders you may already own.
!
ATTENTION
To avoid cracking the removable terminal block, alternate
removal of the slotted terminal block release screws.
