• IP55 is ensured for the front panel of the unit independently mounted to a panel.  Securely seal the mounting surface along the panel cutout once the unit is installed. 
• Set the unit on a vertical surface with its operation buttons at the lower side.  Mounting in other directions may cause heat built up inside the unit and shorten its life span or degrade its performance.
• Ensure that there is sufficient space for ventilation inside the panel.  Do not install above the devices that generate high heat such as heaters, transformers or resistors.  Leave at least 30 mm (1.2 inch) space above, below and behind the unit for maintenance purpose (e.g. wiring, removing or installing).
