We recommend the following Belden cable or its equivalent to connect

the encoder to the module (maximum 50 feet). Use extra twisted pairs to

connect power to the encoder.

Important: Tighten wiring arm connections to 9 inch-pounds of torque.

WARNING: Do not remove the wiring-arm from an

operating module; it will cause the power-up bit status to

change unpredictably until a valid write to the module occurs.

If swing-arm power is lost, turn on the power-up bit and disable

all outputs until a valid write occurs.

Connecting a SingleĆended Output Encoder

Use Figure 3.6 to connect a single-ended output encoder. Connect the

signal line for bit 0 to terminal 1 of the left wiring arm. Connect its return

to terminal 2. Connect bit 1 signal line to terminal 3 and its return to

terminal 4. Continue in this way for all encoder channels.

If the encoder has less than 12 signal bits, jumper the unused input

terminals. For example, if you are using a 10-bit encoder, jumper

terminals 19 and 20 and terminals 17 and 18 on the right wiring arm.
