 However, the warranty expressed here is covered only for products delivered from Hitachi, and will not
be responsible for others damage or loss of products like a motor or any equipment or systems damage
caused by improper usage of the product. We recommend applying safety design which is able to

minimize the consequences on other equipment or system. We advise that the selection of the
delivered product is done with sufficient margin for performance, as well as using redundant design for
other equipment or systems. Also, the compatibility of the product with the customer's intended use is
not warranted, hence the customer has the responsibility to perform validation tests before any
