Configuration
Electrical Connections:
!
Only use wires, electrical cables, and connectors that have proper electrical
insulation for the operating voltages and sufficient capacity for the electrical
current required.
!
Be certain that all electrical components are in good condition. Do not pinch or
damage any wires when installing or operating the TCA. Operate only with the
terminal block cover in place to prevent accidental contact with equipment
carrying hazardous voltages.
!
The electrical input to the TCA must be fused appropriately to prevent injury in
the event of an electrical malfunction.
!
Use wire leads which are short in length to reduce the risk of electromagnetic
interference. Use electrical shielding and ferrite beads as necessary.
!
The application of incorrect voltage to the TCA can result in a hazard or
damage to the TCA and/or secondary equipment.
!
The electrical connections and wires of the TCA and secondary equipment
should be restricted from being cooled below the dew point.
!
Do not exceed the specified electrical ratings of the TCA.
Temperature Controller and Power Supply Connections:
!
For all electrical connection types shown below, the fans should be operated
at their nominally rated voltage. Consult TE Technology, Inc. for operating fans
above or below nominally rated voltage.
• “Single Power Supply, Constant Voltage Connection” may be used for
cooling applications only.
• “Two Power Supplies, Variable Heating/Cooling Connection” may be
used with two separate power supplies: one constant voltage power
supply for the fans and one variable or constant voltage power supply
for the thermoelectric (Peltier) modules. It may be used for heating or
cooling.
• “Temperature Controller Connection” may be used with one power
supply and one temperature controller (unless otherwise specified by
the controller manual). Power supply powers the fans directly and
supplies power to the controller, which then modulates power to the
TCA thermoelectric (Peltier) modules to maintain a set temperature. It
may be used for heating or cooling.
