Precautions For Safe Use - Omron E5AR - MANUAL 2 User Manual

VI

Precautions for Safe Use

(1) Use and store the product within the specified ambient temperature and
humidity ranges. If several products are mounted side-by-side or arranged in a
vertical line, the heat dissipation will cause the internal temperature of the
products to rise, shortening the service life. If necessary, cool the products
using a fan or other cooling method.
(2) Provide sufficient space around the product for heat dissipation. Do not block the
vents on the product.
(3) Use the product within the noted supply voltage and rated load.
(4) Be sure to confirm the name and polarity for each terminal before wiring the
terminal block and connectors.
(5) Do not connect anything to unused terminals.
(6) Use the specified size of crimp terminals (M3, width: 5.8 mm max.) for wiring
the terminal block.
(7) To connect bare wires to the terminal block, use AWG22 to AWG14 (cross-
sectional area: 0.326 to 2.081 mm
AWG28 to AWG16 (cross-sectional area: 0.081 to 1.309 mm
terminals. (Length of exposed wire: 6 to 8 mm)
(8) Ensure that the rated voltage is achieved no longer than 2 s after turning the
power ON.
(9) Turn OFF the power first before drawing out the product. Never touch the
terminals or the electronic components, or subject them to physical shock.
When inserting the product, do not allow the electronic components to contact
the case.
(10) Do not remove the inner circuit board.
(11) Output turns OFF when shifting to the initial setting level in certain modes.
Take this into consideration when setting up the control system.
(12) Allow the product to warm up for at least 30 minutes after the power is turned
ON.
(13) Install surge absorbers or noise filters in devices near the product that generate
noise (in particular, devices with an inductance component, such as motors,
transformers, solenoids, and magnetic coils). If a noise filter is used for the
power supply, check the voltage and current, and install the noise filter as close
as possible to the product. Separate the product as far as possible from
devices generating strong high-frequency noise (e.g., high-frequency welders
and high-frequency sewing machines) or surges.
Do not tie noise filter input/output wires together.
(14) Keep the wiring for the product's terminal block and connector separate from
high-voltage, high-current power lines to prevent inductive noise. Do not run the
wiring parallel to or in the same cable as power lines. The influence of noise
can also be reduced by using separate wiring ducts or shield lines.
(15) Install an external switch or circuit breaker and label them clearly so that the
operator can quickly turn OFF the power.
(16) Do not use the product in the following locations:
· Locations where dust or corrosive gases (in particular, sulfuric or ammonia
gas) are present.
· Locations where icing or condensation may occur.
· Locations exposed to direct sunlight.
· Locations subject to excessive shock or vibration.
· Locations where the product may come into contact with water or oil.
· Locations subject to direct radiant heat from heating equipment.
· Locations subject to extreme temperature changes.
(17) Cleaning: Do not use thinners. Use commercially available alcohol.
