30-2-512. Payment by buyer before inspection. (1) Where the contract requires payment before inspection nonconformity of the goods does not excuse the buyer from so making payment unless:

(a) the nonconformity appears without inspection; or

(b) despite tender of the required documents the circumstances would justify injunction against honor under the provisions of this code (30-5-129(2)).

(2) Payment pursuant to subsection (1) does not constitute an acceptance of goods or impair the buyer's right to inspect or any of the buyer's remedies.
