MANUAL #27
1/8 DIN Solid State Temperature
Indicator Model ETR-9004
All temperature indicators in this series are made to fit
into panel cut-outs which measure 113⁄16” x 35⁄8” (46mm x
92mm). A minimum of 31⁄2” (89mm) in depth is required
for electrical clearances of rear terminal connections.
The following specifications are common to all models:

MOUNTING
When mounting the instrument, it is important the
instrument remains within the ambient temperature
range of 10 to 125°F. Mounting it in any position is
permissible. After inserting the instrument into the
panel, secure it with the mounting bracket provided with
each unit.
•Both solderless terminals or “stripped”leads
can be used for power leads. Only “stripped”leads
should be used for thermocouple connections to
prevent compensation and resistance errors.
•Take care not to over-tighten the terminal screws.
•Unused control terminals should not be used as
jumper points as they may be internally connected,
causing damage to the unit. This indicator is not
to be used in hazardous locations as defined in
Article 500 of the National Electric Code.
