  • Page 29: Mounting With Mounting Spar

    Mounting with mounting spar The mounting variants in this chapter refer to mounting of the device with a mounting spar. HEIDENHAIN recommends mounting with the cable outlet on the right. This mounting option provides a higher vibration resistance. The mounting variants without a mounting spar (mounting by means of the end blocks) are described on Page 20.
