Wiring compartment
The terminal board on the LUT400 allows all inputs and outputs to be connected
simultaneously. Terminal strips can be removed to improve ease of wiring.
CAUTION: Ensure the terminal strips are terminated to the correct location
during re-installation. Failure to do so may result in damage to the device, or
external equipment that is attached.
Note: Recommended torque on terminal clamping screws.
