7 Precautions
Before connecting to external devices, follow the precautions below.
7.1 Installation
When installing the MSD, please observe the following precautions.
● Do not place the MSD on top of another MSD.
● Do not block vent holes. Please secure the space above ambient 30 mm/1.18 inches.
● Do not install the MSD to an enclosed space. When the MSD needs to be installed to EIA rack mount
or an enclosed space, please prepare ventilating equipment to keep the ambient temperature at 40
degrees C/104 degrees F or less. If inadequately vented, the life of parts may be shortened and
operations may be affected.
