Omron E5AN User Manual page 5

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) To reduce induction noise, separate the high-voltage or large-current 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) To allow heat to escape, do not block the area around the product. (Ensure enough space is left for
the heat to escape.)
Do not block the ventilation holes on the case.
(6) When you draw out or draw in the internal mechanism from the housing (E5AN/EN/CN) or draw
out the terminals (E5GN), never touch electrical components inside or subject the internal mecha-
nism or terminals to shock.
(7) Cleaning: Do not use paint thinner or the equivalent. Use standard grade alcohol to clean the product.
(8) On the E5AN/EN/CN, use specified size (M3.5, width 7.2 mm or less) crimped terminals for wiring.
On the E5GN, use AWG24 to AWG14 leads for terminal Nos.1 to 6 (with lead cover peel back allow-
ance of 5 or 6 mm) and AWG28 to AWG22 leads for terminal Nos.7 to 9 (with lead cover peel back
allowance of 5 or 6 mm).
(9) Allow as much space as possible between the E5AN/EN/CN/GN and devices that generate powerful
high-frequency noise (e.g. high-frequency welders, high-frequency sewing machines) or surges.
(10) When executing self-tuning, turn the load (e.g. heater) ON simultaneously with the main unit. If
you turn the main unit ON before turning the load ON, correct self-tuning and optimum control
can 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 E5AN/EN/CN/GN. 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 com-
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 E5AN/EN/CN/GN.
(14) Use within the following temperature and humidity ranges:
· Temperature: -10 to 55°C, Humidity: 25 to 85% (with no icing or condensation)
If the E5AN/EN/CN/GN is installed inside a control board, the ambient temperature must be kept
to under 55°C, including the temperature around the E5AN/EN/CN/GN.
If the E5AN/EN/CN/GN is subjected to heat radiation, use a fan to cool the surface of the E5AN/
EN/CN/GN to under 55°C.
(15) Store within the following temperature and humidity ranges:
· Temperature: -25 to 65°C, Humidity: 25 to 85% (with no icing or condensation)
(16) Never place heavy objects on, or apply pressure to the E5AN/EN/CN/GN as it may cause it to
deform and deteriorate during use or storage.
(17) Avoid using the E5AN/EN/CN/GN in places near a radio, television set, or wireless installation.
These devices can cause radio disturbances which adversely affect the performance of the E5AN/
EN/CN/GN.
