Introduction
Introduction
This unit can be installed in a rack. When installing the unit in a rack,
to ensure efficient cooling, give attention to the following points.
• Ensure that the location provides good air flow and ventilation.
• Never block the cooling-fan intake port or ventilation port in
the front and rear panel.
• Avoid using the M-380 in sealed-type rack mounts. As this type
of rack does not permit heated air within the rack to be
expelled, the heated air is drawn into the M-380 as a result, thus
preventing adequately efficient cooling.
• If the rack’s rear panel is not removable, ensure that a
ventilation port or exhaust fan is provided at the top of the
rack’s rear panel to expel any accumulated heat.
• If the M-380 is mounted in a portable rack, remove both the
front and rear rack covers before use to ensure that the M-380’s
front and rear panels remain unobstructed.
• When installing the unit on a rack, detach the rubber feet from
the bottom of the unit.
Use due caution when mounting the M-380 in a rack or other
enclosure so you don’t get your fingers wedged or pinched.
Connect one end of the supplied AC power cord to a grounded AC
outlet, and the other end to the AC INPUT connector to provide
power for the M-380’s internal power supply.
Use only the supplied power cords to prevent damage to the
units.
