Do not operate the TCA if the heat-sink fan is not operational. This could
cause damage and create hazards from the heat sink being greater than 60 °C.
Do not operate the TCA if the heat-sink fan is operational but exhibits bearing
noise or is otherwise not operating as normally expected.
!
Frost/ice should not be allowed to form on the heat sink, fan(s), or cold sink (if
so equipped) as this could obstruct air flow and decrease performance and/or
cause damage to the TCA and secondary equipment. If frost/ice contacts the
cold-sink or heat-sink fan, de-energize the TCA until the frost/ice has been
removed.
Do not operate TCA without finger guards. This could result in a hazard.
Portions of the TCA (the heat sink, for example) will become warmer
than the ambient temperature. They can become hotter than 60 °C even if
control temperatures of greater than 60 °C are not desired. The operating
temperature of the TCA depends on many factors: ambient temperature, input
power, and heat pumping. If the TCA is to be used in conditions where a portion
of the TCA could possibly exceed 60 °C (for example, if the TCA is operated in
ambient temperatures greater than 35 °C) test the surface temperatures of the
TCA under the worst-case operating conditions of maximum ambient
temperature, highest heat pumping, and maximum input power. If any portion of
the TCA exceeds 60 °C place adequate guards around the TCA to prevent
contact with hot surfaces.
See “Electrical Connections” section for proper connection from controller/power
supply.
Do not:
1. Install the TCA,
2. Attach anything to the TCA, or
3. Operate the TCA or attached equipment,
that would create a voltage potential of 50 V or more on the TCA.
