Step 1. Install the terminal block assembly on the studs in the lower left of the cabinet. It may be necessary to temporarily remove the end stop or slide the terminals on the DIN rail to access the nuts. Step 2. Route the accessory cables toward the left of the cabinet interior, and down the back left corner towards the ground lug. Follow the main harness along the bottom left edge of the cabinet towards the control module. Step 3. Unbolt the wire clamps holding the main harness in place from near the control cable receptacle to the uppermost clamp at the side of the control module. Step 4. Use wire ties to secure the accessory cables to the main harness along this section. Step 5. Install the existing spiral wrap around the section of the cable bundle that passed through the wire clamp at the bottom of the swing panel. Step 6. Route the cable bundle through the wire clamps and secure the clamps with the nuts that were removed at the beginning of Step 3. Step 7. Route the cables over the top of the control module. Loosen each of the two existing cable clamps from their respective studs, attach an additional clamp opposite each existing clamp so the accessory cables run parallel to the wire harness, and then fasten each pair of clamps to the studs. If the unit is already equipped with the two extra cable clamps, route the new cable through them. Step 8. Install the included accessory terminal block label on the inside left side wall of the cabinet. Step 9. If installed, remove the jumpers connecting Z07 to Z26 and Z10 to Z28. Step 10. Remove any customer-installed wires connected to the Voltages terminal block (connections Z07 through Z12) of the control module. Reconnect these wires to the appropriate positions on the bottom side of the Accessory terminal block, per Figure 1, and the label installed in Step 8. Step 11. Remove the STC connected to the control module at positions Z07 through Z12. Step 12. Install the STC at the ends of the harness to the Voltages connections (Z07 through Z12) on the control module. Step 13. Attach the remaining wires from the Accessory terminal block per their labels and Table 1. Remove the labels if desired. Step 14. If the jumpers referenced in Step 9 were not present, remove the jumper wires on the Accessory terminal block between positions 1 and 7 and positions 4 and 10.
