  • Page 47: Installation

    The power supply should be in the range of +9V to +28VDC. Maxon can supply, as an accessory, a mains power supply which is capable of powering MM-6854 modems. This power supply has the part number CA6823 and is a 12V, 1A power supply. 7.4 Fusing It is strongly suggested that fuses for the data modem, and any associated equipment, are located in a place away from the main fusebox.

  • Page 48: Cabling

    If possible, run RF cables separately from other cables and keep RF cables apart from one another to avoid interference / coupling. 7.6 Fixing We recommend that the MM-6854 data modem is securely fixed to a surface, either directly, or with a suitable bracket. The fixing hole dimensions are shown below: 163mm 2 off holes 6.7mm dia.
