NOTICE
Be sure to observe these precautions to ensure safe use.
(1) Do not wire unused terminals.
(2) Be sure to wire properly with correct polarity of terminals.
(3) T o reduce induction noise, separate the highĆvoltage or largeĆcurrent power lines from other lines,
and avoid parallel or common wiring with the power lines when you are wiring to the terminals.
We recommend using separating pipes, ducts, or shielded lines.
(4) Do not use this product in the following places:
•
Places subject to dust or corrosive gases (in particular, sulfide gas and ammonia gas)
•
Places subject to high humidity, condensation or freezing
•
Places subject to direct sunlight
•
Places subject to vibration and large shocks
•
Places subject to splashing liquid or oily atmosphere
•
Places directly subject to heat radiated from heating equipment
•
Places subject to intense temperature changes
(5) T o allow heat to escape, do not block the area around the product. (Ensure that enough space is
left for the heat to escape.)
•
Do not block the ventilation holes on the casing.
(6) When you draw out or draw in the internal mechanism or the terminal unit from the housing,
never touch electrical components inside or subject the internal mechanism to shock.
(7) Cleaning: Do not use paint thinner or the equivalent. Use standard grade alcohol to clean the prodĆ
uct.
(8) Use specified size (M3.5, width 7.2 mm or less) crimped terminals for wiring.
(9) Allow as much space as possible between the E5EN and devices that generate powerful highĆfreĆ
quency noise (e.g. highĆfrequency welders, highĆfrequency sewing machines) or surges.
(10) When executing selfĆtuning, turn the load (e.g. heater) ON simultaneously or before you turn the
the main unit ON. If you turn the the main unit ON before turning the load ON, correct selfĆtuning
results and optimum control may no longer be obtained.
(11) Use a 100 to 240 VAC (50/60 Hz), 24 VAC (50/60 Hz) or 24 VDC power supply matched to the power
specifications of the E5EN. Also, make sure that rated voltage is attained within two seconds of
turning the power ON.
(12) 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 comĆ
ponent).
(13) When mounting a noise filter on the power supply, be sure to first check the filter's voltage and
current capacity, and then mount the filter as close as possible to the E5EN.
(14) Use within the following temperature and humidity ranges:
•
T emperature: Ć10 to 55
_
C, Humidity: 25 to 85% (with no icing or condensation)
If the E5EN is installed inside a control board, the ambient temperature must be kept to under
55
_
C, including the temperature around the E5EN.
If the E5EN is subjected to heat radiation, use a fan to cool the surface of the E5EN to under
55
_
C.
(15) Store within the following temperature and humidity ranges:
•
T emperature: Ć25 to 65
_
C, Humidity: 25 to 85% (with no icing or condensation)
(16) Never place heavy objects on, or apply pressure to the E5EN as it maycause it to deform and deteriĆ
orate during use or storage.
(17) Avoid using the E5EN in places near a radio, television set, or wireless installation. These devices
can cause radio disturbances which adversely affect the performance of the E5EN.
