3.2.1.13 Chassis Temperature Control
The 7705 SAR-Hm and 7705 SAR-Hmc chassis are passively cooled using fins for
heat dissipation. Clearance requirements must be followed to ensure proper airflow
around the chassis (see Chassis Clearance and Thermal Requirements).
System temperature is monitored. An Overheat alarm is raised if the system ambient
operating temperature range is exceeded. The Overheat alarm is cleared when the
system temperature falls within the specified operating range.
3.2.1.14 Chassis Mounting Options
The 7705 SAR-Hm and 7705 SAR-Hmc chassis are designed to support indoor and
outdoor mounting options. Outdoor installation requires the use of a cabinet or
enclosure that provides weather protection in an extended temperature-controlled
environment. The following mounting options are available.
• 7705 SAR-Hm and 7705 SAR-Hmc DIN rail mount
The chassis is factory-equipped with a rear-mount DIN rail clip so that the
chassis can be mounted on a horizontal 35 mm top-hat rail, as outlined in the
EN 50022 standard. See DIN Rail-mounting the Chassis for more information.
The HV-PS35 also comes factory-equipped with a DIN rail clip so that the PSU
can be DIN rail-mounted adjacent to the chassis. See DIN Rail-mounting the
HV-PS35 for mounting options and instructions.
• 7705 SAR-Hm and 7705 SAR-Hmc flat-surface mount
The chassis can be installed on a flat surface, such as a table or desktop.
7705 SAR-Hm includes four rubber feet that are shipped with the chassis in a
bag. The feet are self-adhesive and must be applied to the bottom of the chassis
if this mounting option is used. Restrictions apply. See Mounting the Chassis on
a Flat Surface.
Warning: If an Overheat alarm occurs, take immediate action to cool the operating
environment. If the system internal temperature continues to increase, system functions will
be affected and can shut down, which may result in equipment damage.
Note: An Uninterruptable Power Supply (UPS) is available for powering the 7705 SAR-Hm
and 7705 SAR-Hmc outdoors. Refer to the UPS vendor manual for information on how to
connect the UPS unit.
