Be sure to observe the following precautions to prevent operation failure, malfunction, or adverse affects
on the performance and functions of the product. Not doing so may occasionally result in unexpected
events. Use the product within specifications.
1) The product is designed for indoor use only. Do not use or store the product in any of the following
locations.
• Places directly subject to heat radiated from heating equipment.
• Places subject to splashing liquid or oil atmosphere.
• Places subject to direct sunlight.
• Places subject to dust or corrosive gas (in particular, sulfide gas and ammonia gas).
• Places subject to intense temperature change.
• Places subject to icing and condensation.
• Places subject to vibration and large shocks.
2) Use and store the Digital Temperature Controller within the rated ambient temperature and humidity.
Gang-mounting two or more temperature controllers, or mounting temperature controllers above each
other may cause heat to build up inside the temperature controllers, which will shorten their service
life. In such a case, use forced cooling by fans or other means of air ventilation to cool down the
Digital Temperature Controllers.
3) To allow heat to escape, do not block the area around the product. Do not block the ventilation holes
on the product.
4) Be sure to wire properly with correct polarity of terminals.
5) Use the specified size of crimp terminals for the E5CN, E5AN, or E5EN (M3.5, width of 7.2 mm or
less). For open-wired connections to the E5CN, E5AN, or E5EN, use stranded or solid copper wires
with a gauge of AWG24 to AWG14 (equal to a cross-sectional area of 0.205 to 2.081 mm
2
). (The
stripping length is 5 to 6 mm.) Up to two wires of the same size and type or two crimp terminals can
be connected to one terminal. Do not connect more than two wires or more than two crimp terminals
to the same terminal.
Use the specified size of crimp terminals for the E5GN (M3.0, width of 5.8 mm or less). For open-
wired connections to the E5GN, use stranded or solid copper wires with a gauge of AWG24 to
AWG18 (equal to a cross-sectional area of 0.205 to 0.8231 mm
2
). (The stripping length for screw
terminals is 6 to 8 mm. The stripping length for screwless clamp terminals is 10 mm. The stripping
length for auxiliary output 2 is 6 mm.) Up to two wires of the same size and type or two crimp
terminals can be connected to one terminal. Do not connect more than two wires or more than two
crimp terminals to the same terminal.
Ferrules for screwless clamp terminals must be 0.8 to 1.4 mm in diameter and the exposed conductor
must be 8 to 12 mm in length. Ferrules for auxiliary output 2 must be 0.8 to 1.4 mm in diameter and
the exposed conductor must be 6 mm in length.
6) Do not wire the terminals which are not used.
7) To avoid inductive noise, keep the wiring for the Digital Temperature Controller's terminal block away
from power cables carry high voltages or large currents. Also, do not wire power lines together with or
parallel to Digital Temperature Controller wiring. Using shielded cables and using separate conduits or
ducts is recommended.
Attach a surge suppressor or noise filter to peripheral devices that generate noise (in particular,
motors, transformers, solenoids, magnetic coils or other equipment that have an inductance
component).
When a noise filter is used at the power supply, first check the voltage or current, and attach the noise
filter as close as possible to the temperature controller.
