Operating Conditions

Safety

The module presents no hazard to the user.

EMC

The module is designed to operate within an enclosed host system that provides
adequate EMC shielding. Operation within the EU EMC guidelines is only guaranteed
when the module is installed within an appropriate host system.

The module is protected from damage by fast voltage transients introduced along
output cables from outside the host system.

Short-circuiting any output to ground does not cause the host PC system to lock up
or reboot.

General Requirements

The module must be fixed to a TIM40-compliant carrier board.

The SMT395 TIM is in a range of modules that must be supplied with a 3.3v power
source. In addition to the 5v supply specified in the TIM specification, these new
generation modules require an additional 3.3v supply to be presented on the two
diagonally-opposite TIM mounting holes. The lack of this 3.3v power supply should
not damage the module, although it will obviously be inoperable; prolonged operation
under these circumstances is not recommended.

The SMT395 is compatible with all Sundance TIM carrier boards. It is a 5v tolerant
module, and as such, it may be used in mixed systems with older TIM modules,
carrier boards and I/O modules.

Use of the TIM on SMT327 (cPCI) motherboards may require a firmware upgrade. If
the top right LED on the SMT395 remains illuminated once the TIM is plugged in and
powered up, the SMT327 needs the upgrade. The latest firmware is supplied with all
new boards shipped. Please contact Sundance directly if you have an older board
and need the upgrade.

The external ambient temperature must remain between 0

°C and 40°C, and the

relative humidity must not exceed 95% (non-condensing).

Power Consumption

The power consumption of this TIM is dependent on the operating conditions in terms
of core activity and I/O activity.
