Connect this grounding stud to your equipment ground. Torque the nut to 5 in-lbs maximum when connecting to your equipment ground. ATTENTION: Do not overtighten the nut on the grounding stud when connecting the wire. Damage to the module could result. Refer to Programmable Controller Wiring and Grounding Guidelines (770-4.) for further information. 4

Only block I/O modules with all inputs or all outputs can use complementary I/O. NOTE: Set switch SW 3 to 0 if this rack will have a unique address (not complemented). If this rack address is a duplicate of another I/O block or chassis, set the switch to for primary or 0 for complementary. Refer to Table C for the complementary I/O rack address. 6 Series A block I/O modules do not support complementary I/O. If using series A modules, set switch SW 3 to 0.

9 Cat. No. 79-6A0 Series B The SLC 500 controllers communicate with the block I/O using an I/O Scanner module (cat. no. 747-SN series A). Refer to the user manual for the 747-SN/A Scanner module for more information. Note: This block I/O module is not compatible with the 747-DSN Distributed I/O Scanner module. Termination Resistor A termination resistor must be installed on the last block in a series. Connect the resistor as shown in Figure 7.
