For applications that require cyclic switching on and off of the drive converter, main- tain an off-time of at least 5 min. If you require shorter cycle times please contact KEB Automation KG. Short-circuit proof The drive converters are conditional short-circuit proof. After resetting the internal pro- tection devices, the function as directed is guaranteed. -
Page 21: Disposal
Drive converters with safety function are limited to a service life of 20 years. Then the devices must be replaced. Drive converters of the KEB Automation KG are professional, electronic devices exclu- sively for further industrial processing (so-called B2B devices). Thus the marking does not occur with the symbol of the crossed-out wheeled bin, but by the word mark and the date of manufacture. -
