3. TION Erratic System Operation Hazard Failure to follow proper wiring practices can introduce disruptive electrical interference noise Keep wiring at least one foot away from large inductive loads such as motors line starters lighting ballasts and large power distribution panels Shielded cable is required in installations where these guidelines cannot be met Ground shield only to grounded controller case IMPORTANT All wiring must comply with local codes and ordinances NOTES Terminal screws are provided on the device for wiring connections Wiring to device is low voltage and need not be in conduit unless required by code 1 Connect correct control wires from the Q7300 subbase to the T7147 see Fig 4 and 5 2 Ensure that Q7300 subbase switch 5 local remote sensor select switch is in the OFF position Refer to the T7300 Q7300 Specification sheet form 63 4038 for details IMPORTANT The ground GND connection at the T7147 is required Use the junction box or conduit for a convenient grounding location 3 Ensure all connections are tight and secure Loose or intermittent wire connections cause inconsistent system operation 4 When installation is complete perform the checkout procedure see the Checkout section 63 4065 1 4 Averaging Sensors When the controlled zone is a large area it can be advantageous to use a T7147 and several remote temperature sensors dispersed throughout the a
