CAUTION
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 life expectancy, contact fusing or burning may occasionally occur. Always
consider the application conditions 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 0.90 N•m. Loose screws may occasionally result in fire.
Set the parameters of the product so that they are suitable for the system being controlled. If they are not suitable,
unexpected operation may occasionally result in property damage or accidents.
A malfunction in the Digital Controller may occasionally make control operations impossible or prevent
alarm outputs, resulting in property damage. To maintain safety in the event of malfunction of the Digital
Controller, take appropriate safety measures, such as installing a monitoring device on a separate line.

The E5
@
N-H is set for a K thermocouple (input
type of 5) by default. If a different sensor is used,
an input error (
s.err
) will occur. Check the setting
of the Input Type parameter.
• A heater burnout alarm, heater short alarm, heater overcurrent alarm, or input alarm is output to the output to which the alarm 1 functi on is assigned.
• Since the voltage output (control output) is not electrically insulated from the internal wiring, one or other of the control output terminals must be left
unearthed when using an earthed thermocouple thermometer. (Connection makes measurements unreliable due to sneak currents.)
• The last character of the lot number “R” indicates that reinforced insulation is provided between input power supply, relay outputs, and between other
terminals.
Conformance to EN/IEC Standards
This is a class A product.
In residential areas it may cause radio
interference, in which case the user may
be required to take adequate measures
to reduce interference.
Conformance to Safety Standards
Reinforced insulation is
provided between input power
supply, relay outputs, and
between other terminals.
Check the wiring before turning ON the power supply.
Check the setting of the Input Type parameter,
check the input wiring, and check for broken or
shorts in the temperature sensor.
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 the product outdoors. Do not use or store the product
in any of the following locations.
•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/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. To connect bare wires to the
terminal block, use copper braided or solid wires with a gage of AWG24 to AWG14 (equal to cross- sectional
area of 0.205 to 2.081 mm
2
). (The stripping length is 5 to 6 mm.) Up to two wires of same size and type, or
two crimped terminals can be inserted into a single terminal.
(6) Do not wire the terminals which are not used.
(7) Allow as much space as possible between the controller 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 ON the power using a switch or
relay contact. If the voltage is applied gradually, the power may not be reset or output malfunctions may
occur.
(10) Make sure that the Digital Controller has 30 minutes or more to warm up after turning ON the power before
starting actual control operations to ensure the correct temperature display.
(11) When executing self-tuning, turn the load and the unit ON simultaneously, or turn the load ON before you
turn the controller ON.
(12) A switch or circuit breaker should be provided close to this unit.
The switch or circuit breaker should be within easy reach of the operator, and must be marked as a
disconnecting means for this unit.
(13) 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.
(14) Do not use paint thinner or similar chemical to clean with. Use standard grade alcohol.
(15) Design system (control panel, etc) considering the 2 second of delay that the controller’s output to be set
after power ON.
(16) The output may turn OFF when shifting to certain levels. Take this into consideration when performing
control.
(17) Refer to the instruction sheet for installing Option unit (E53CNH03N / E53-CNHBN / E53-CN03N /
E53-CNBN / E53-CNHH03N / E53-CNQ03N / E53-CNQHN / E53-CNPBN / E53-CNPHN / E53-CNQBN /
