General Safety Warnings
This manual is available in English only. It must be read and followed carefully before installation
and operation. All warnings in this Operation Manual apply to both the TC‐48‐20 and TC‐48‐20 OEM
versions of the controller. Where “TC‐48‐20” is referenced, it is used generically and interchangeably for
both the TC‐48‐20 and the TC‐48‐20 OEM versions of the controller, except where otherwise specifically
noted.
THE LATEST REVISION OF THIS MANUAL IS AVAILABLE AT www.tetech.com . Verify that you are
using the latest revision available.
Do not use in an explosive or potentially explosive environment.
The TC‐48‐20 should not be used as a toy, or serious injury could result. The TC‐48‐20 should only
be used for its intended purpose of providing temperature control of TE Technology’s
thermoelectric devices only. The controller is intended for light industrial, laboratory, or similar
use. It is not for household use or medical use.
Do not use if the controller has been damaged.
Only qualified technicians should install and operate this controller with the appropriate personal
protective equipment.
Do not use the TC‐48‐20 to control capacitive or inductive loads or the controller could be
damaged and/or overheat. Examples of capacitive or inductive loads include but are not limited
to: motors, fans, filters, and solenoids.
Do not allow the electrical connections or components on the printed circuit board, including
those on the reverse side of the JP3, JP4 and JP5 connectors, to touch any electrically conductive
surfaces.
Do not operate in an environment where the controller could come in contact with
condensation, water, metal shavings, dirt or other contaminants, or electrically conductive
materials.
Use ESD (Electro Static Discharge) protection when installing the controller or coming in contact
with electrical connections or components on the controller.
Do not touch any of the electrical connections or components of the TC‐48‐20 while the
controller is energized. Doing so can disrupt the function of the controller.
The printed circuit board underneath JP4 and exposed components on the printed circuit board
could exceed 70 °C under normal operation. Use caution! Protect against accidental contact with
hot surfaces.
Improper tuning of this temperature controller can lead to overheating of the load (e.g. cooling
assembly, heater, etcetera) and other related equipment.
Use protection devices to prevent hazardous conditions and/or damage to equipment.
Each power input that is used must be fused separately. Alternately, a power supply with
integral over current protection can be used if it is appropriately sized for protecting the
controller/TE device.
JP4 Pin 1 (+ power in) and JP4 Pin 3 (+ load output) are connected to each other inside the
controller. When JP4 Pin 1 is energized a voltage will be present on JP4 Pin 3, even if the output
of the controller is off.
