Precautions for Safe Use
1. Do not use this product in the following places:
• 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 within the rated temperature and humidity ranges.
Provide forced-cooling if required.
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 specified size (M3.5, width 7.2 mm or less) crimped
terminals for wiring. Use wires with a gage of AWG24 to AWG14
(equal to cross-sectional areas of 0.205 to 2.081 mm
2
). (The
stripping length is 5 to 6 mm.).
6. Do not wire the terminals that are not used.
7. Allow as much space as possible between the product and
devices that generate a powerful high-frequency or surge.
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.
8. Use this product within the rated load and power supply.
9. Make sure that the rated voltage is attained within two seconds
of turning the power ON.
10. Make sure the product has 30 minutes or more for warm up.
11. A switch or circuit breaker must be provided close to the product.
The switch or circuit breaker must be within easy reach of the
operator, and must be marked as a disconnecting means for this
unit.
12. Always turn OFF the power supply before pulling out the interior
of the product, and never touch nor apply shock to the terminals
or electronic components. When inserting the interior of the
product, do not allow the electronic components to touch the
case.
13. Do not use paint thinner or similar chemical to clean with. Use
standard grade alcohol.
14. Design the system (e.g., control panel) considering the 2
seconds of delay that the product's output to be set after power
ON.
15. The output may turn OFF when shifting to certain levels. Take
this into consideration when performing control.
16. Refer to the instruction sheet for installing Option Unit (E53-
CN03N/E53-CNBN/E53-CNPBN).
Do not touch the terminals while power is being supplied.
Doing so may occasionally result in minor injury due to
electric shock.
Do not allow pieces of metal, wire clippings, or fine
metallic shavings or filings from installation to enter the
product. Doing so may occasionally result in electric
shock, fire, or malfunction.
Do not use the product where subject to flammable or
explosive gas. Otherwise, minor injury from explosion
may occasionally occur.
Never disassemble, modify, or repair the product or touch
any of the internal parts. Minor electric shock, fire, or
malfunction may occasionally occur.
Caution: Risk of Fire and Electric Shock
a) This product is UL listed as Open Type Process
Control Equipment. It must be mounted in an
enclosure that does not allow fire to escape externally.
b) More than one disconnect switch may be required to
de-energize the equipment before servicing.
c) Signal inputs are SELV, limited energy.
d) Caution: To reduce the risk of fire or electric shock, do
not interconnect the outputs of different Class 2
circuits.
If the output relays are used past their rated load or life
expectancy, contact fusing or burning may occasionally
occur. Always consider the application conditions and the
inrush current, and use the output relays within their rated
load and electrical life expectancy. The life expectancy of
output relays varies considerably with the output load and
switching conditions.
Tighten the terminal screws to between 0.74 and 0.9 N·m.
Loose screws may occasionally result in fire.
Set the parameters of the product so that they are
suitable for the system. If they are not suitable,
unexpected operation may occasionally result in property
damage or accidents.
Warning: To reduce the risk of electric shock or fire, install
in a Pollution Degree 2 environment (a controlled
environment relatively free of contaminants).
A malfunction in the product may occasionally make
control operations impossible or prevent alarm outputs,
resulting in property damage to connected equipment
and machinery. To maintain safety in the event of
malfunction of the product, periodically check the Limit
Controller's operation.
