Safety Precautions
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.
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 and wiring of the Product so that they
are suitable for the system being controlled. Unexpected
operation may occasionally result in property damage or
accidents.
A malfunction in the Product may occasionally make
control operations impossible or prevent alarm outputs,
resulting in property damage. To maintain safety in the
event of malfunction of the Product, take appropriate safety
measures, such as installing a monitoring device on a
separate line.
Precautions for Safe Use
Be sure to observe the following precautions to prevent failure to
operate, malfunction, or adverse effects on the performance and
functions of the Thermostat. Not doing so may occasionally result in
unexpected events.
1. The Product is designed for indoor use only.
Do not use the Product outdoors or in any of the following
locations.
• Locations directly subject to heat radiated from heating
equipment
• Locations subject to water or oil
• Locations subject to direct sunlight
• Locations subject to dust or corrosive gas (in particular, sulfide
gas and ammonia gas)
• Locations subject to sudden or extreme temperature changes
• Locations subject to icing or condensation
• Locations subject to vibration or shock
2. Use and store the Product 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.
4. Be sure to wire the Product properly with the correct terminal
polarity.
5. Use the specified size of crimped terminals for wiring (M3.5, width
of 6.8 mm or less). To connect bare wires to the terminals, use
copper wires with a gauge of AWG24 to AWG14 (equal to a
cross-sectional area of 0.205 to 2.081 mm2). (The stripping length
is 5 to 6 mm.) Do not connect more than two wires or two crimp
terminals to one terminal. When connecting two wires, they must
be of the same size and type.
6. Do not connect anything to terminals that are not used.
7. Allow as much space as possible between the Thermostat and
devices that generate powerful high frequencies or surges.
Separate the wiring to the Thermostat from high-voltage or highcurrent lines, and do not place the wiring to the Thermostat in
parallel with or in the same wiring paths as power lines.
8. Use this Product within the rated load and power supply
specifications.
9. Turn ON the power supply at least 30 minutes prior to starting
control operations.
10. A switch or circuit breaker must be provided close to the
Thermostat. The switch or circuit breaker must be within easy
reach of the operator, and must be marked as a disconnecting
means for the Thermostat.
11. Do not use paint thinner or similar solvents to clean the
Thermostat. Use standard grade alcohol.
12. Design the system (e.g., the control panel) considering the 2.5
second of delay between turning ON the Thermostat and
stabilization of the Thermostat's output.

Precautions for Correct Use
Mounting the Thermostat
1. Using the PTF14A Socket or PTF14A-E Socket with Finger
Protection, mount the Thermostat to the bracket that is provided.

2. The structure does not allow the case to be removed. Do not apply
excessive force when mounting the Thermostat.
Settings
1. E5L-A@ Temperature Dial
• The temperature dial has some backlash. To adjust the
temperature more accurately, turn the dial clockwise when
adjusting the temperature.
• Do not change the setting of the temperature dial more than 20
times.
• Do not attempt to turn the dial past the range of the setting scale.
Applying excessive force may damage the Thermostat.
2. E5L-A@ Hysteresis Dial
• This dial can be used to set hysteresis for the ON/OFF operation.
Turn the dial clockwise to increase the hysteresis and
counterclockwise to reduce the hysteresis. Increase the hysteresis
to extend the life of the relay by preventing relay chattering caused
by the control output turning ON and OFF frequently.
• Do not change the setting of the temperature dial more than 20
times.
Mounting the Thermistor
• Select a location for the temperature sensor of the thermistor
where the temperature distribution of sensing objects will not be
changed by installation.
• Insert the temperature sensor as far in as possible.
• When measuring fluid temperature, the thermistor should be
installed against the current. Before mounting, take factors such as
the bending moment of inertia and vibration into consideration.
• Do not apply mechanical force to the temperature-sensing part of
the thermistor.
• The E52-THE@@ Thermistor can be used for applications that
require metal protective tubing. Consult with your OMRON
representative.
Other Precautions
• Do not use the E5L-C@ if the front sheet is peeling or torn.
• Use appropriate tools to disassemble the Thermostat for disposal.
