Enclosure surface mounting
Remove the front cover and wiring cover to mount the drive unit to the surface. (Remove the covers in the directions of the
arrows.)
(2) Environment
Before installation, check that the environment meets the specifications on page 38.
NOTE
y When encasing multiple drive units, install them in parallel as a cooling
measure.
y Install the drive unit vertically.
y For heat dissipation and maintenance, allow minimum clearance shown
in the figures below from the drive unit to the other devices and to the
inner surface of the enclosure.
* When using the drive units at the surrounding air temperature of 40°C or less, the drive units can be installed without any clearance between
them (0cm clearance).
Note
y Install the drive unit on a strong surface securely and vertically with bolts.
y Leave enough clearances and take cooling measures.
y Avoid places where the drive unit is subjected to direct sunlight, high temperature and high humidity.
y Install the drive unit on a nonflammable wall surface.
