Due to the (SEE NOTE) .25 many areas of liability that may be encountered when dealing 4.13 4.84 (6) with these applications, the following statement of Company (105) (123) .21 Policy applies: .13 3.70 (5) (3) (94) TB Wood’s Incorporated AC Inverter products are sold for suitability with explosion proof AC motors rated for use with PWM inverters. These motors must be UL listed for use with either TB Wood’s AC inverters or with PWM inverters and used within the specified speed ranges and 5.40 carrier frequencies. TB Wood’s accepts no responsibility (137) 6.26 for any direct, incidental or consequential loss, cost or (159) damage associated with the misapplication of our AC products in these applications.
