Installing the Module

1. Make sure your SLC power supply has adequate reserve current capacity.

The  module requires 250 mA at +5V dc. 

2. Align the full-sized circuit board with the chassis card guide as shown below.

The first slot of the first chassis is reserved for the processor.

3. Slide the module into the chassis until the top and bottom latches catch. 

To  remove the module, press the release clips at the top and bottom of the module  and slide it out. 

4. Cover all unused card slots with the Card Slot Filler, catalog number 1746-N2.

Important Wiring Considerations

Use the following guidelines when planning the system wiring for the module:

• Install the SLC 500 system in a NEMA-rated enclosure.

• Disconnect power to the SLC processor and the module before wiring.

• Make sure the system is properly grounded.

• Group this module and low-voltage DC modules away from AC I/O or 

high-voltage DC modules.

• Shielded cable is required for high-speed input signals A, B, and Z. Use 

individually shielded, twisted pair cable lengths up to 300 m (1000 ft.).

• Shields should be grounded only at one end. Ground the shield wire outside 

the module at the chassis mounting screw. Connect the shield at the encoder 

end only if the housing is isolated from the motor and ground.

• If you have a junction in the cable, treat the shields as a conductor at all 

junctions. Do not ground them to the junction box.
