Be sure to observe the following precautions to prevent malfunction
or adverse affects on the performance or functionality of the product.
Not doing so may occasionally result in faulty operation. Do not
handle the Digital Temperature Controller in ways that exceed the
ratings.
1. This product is specifically designed for indoor use only.
Do not use this product in the following places:
•Places directly subject to heat r
adiated 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 vibra
tion and large shocks.
2. Use and store the product within the rated ambient temperature
and humidity.
Gang-mounting two or more Digital Tempera ture Controllers, or
mounting Digital Temperature Controllers above each other may
cause heat to build up inside the Digital Temperature Controllers,
which will shorten their service life. In such a case, use forced
cooling by fans
or other means of air ventilation to cool down the
Digital Temperature Controllers.
3. To allow heat to escape, do not block the area around the Digital
Temperature Controller.
Do not block the ventilation holes on the Digital Temperature
Controller.
4. Be sure to wire properly with correct signal name and polarity of
terminals.
5. Use copper stranded or solid wires to connect bare wires.
Recommended Wire
*1. Please use Ferrules with UL certification (R/C).
Use the specified size of crimped terminals to wire the E5CC,
E5EC, E5AC, E5DC, and E5GC (models with screw terminal) and
the E5@C-T and E5CC-U (plug-in models).
Recommended Crimped Terminal Size
For the E5@C-B (Push-In Plus model), connect only one wire to
each terminal.
For other models, up to two wires of same size and type, or two
crimp terminals, can be inserted into a single terminal.
When connecting two wires to one terminal on an E5GC Digital
Temperature Controller with a screwless clamp terminal, use two
crimped ferrules with a diameter of 0.8 to 1.4 mm and an exposed
conductor length of 8 to 12 mm. *2
*2. The E5GC Digital Temperature Controller with screwle
ss
clamp terminal underwent UL testing with one braided wire
connected.
6. Do not wire the terminals that are not used.
7. Use a commercia l power supply for the power supply voltage input
to a Digital Temperature Controller with AC input specifications.
Do not use the output from an inverter as the power supply.
Depending on the output characteristics of the inverter,
temperature increases in the Digital Temperatu
re Controller may
cause smoke or fire damage even if the inverter has a specified
output frequency of 50/60 Hz.
8. To avoid inductive noise, keep the wiring for the product’s terminal
block away from power cables carry high voltages or large
currents. Also, do not wire power lines together with or parallel to
product wiring. Using shielded cables and using separate conduits
or ducts is
recommended.
Attach a surge suppressor or noise filter to peripheral devices that
generate noise (in particular, motors, transformers, s olenoids,
magnetic coils, or other equipment that have an inductance
component).
When a noise filter is used at the power supply, first check the
voltage or current, and attach the noise filter as close as possible
to the product.
Allow as much space as possible between the produ ct and
devices that generate powerful high frequencies (high-frequency
welders, high-frequency sewing machines, etc.) or surge.
9. Use this product within the rated load and power supply.
10.Make sure that the rated voltage is attained within two seconds of
turning ON the power using a switch or relay contact. If the volta
ge
is applied gradually, the power may not be reset or output
malfunctions may occur.
11.Make sure that the Digital Temperature 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.
12.When executing self-tuning with E5@C, turn ON power to the load
(e.g., hea
ter) at the same time as or before supplying power to the
product. If power is turned ON to the product before turning ON
power to the load, self-tuning will not be performed properly and
optimum control will not be achieved.
13.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
u
nit.
14.Use a soft and dry cloth to clean the product carefully. Do not use
organic solvent, such as paint thinner, benzine or alcohol to clean
the product.
15.Design the system (e.g., control panel) considering the 2 seconds
of delay that the product's output to be set after power ON.
16.The output may turn OFF when you move to the initial setting level.
Take this into consideration when performing control oper
ations.
17.The number of non-volatile memory write operations is limited.
Therefore, use RAM write mode when frequently overwriting data
during communications or other operations.
18.Always touch a grounded piece of metal before touching the
Digital Temperature Controller to discharge static electricity from
your body.
19.Use suitable tools when taking the Digital Temperature Controller
apart for dis
posal. Sharp parts inside the Digital Temperature
Controller may cause injury.
20.For compliance with Lloyd’s standards, the E5CC, E5CC-B,
E5EC-B, E5CC-U, E5EC, E5AC, and E5DC must be insta lled
under the conditions that are specified in Shipping Standards.
21.For the Digital Temperature Controller with two Setup Tool ports
(E5EC/E5EC-B/E5AC/E5DC/E5GC), do not connect cables to
both ports at the same time. The Digital Temperature Controller
may be d
amaged or may malfunction.
22.Do not place heavy object on the Conversion Cable, bend the
cable past its natural bending radius, or pull on the cable with
undue force. The Digital Temperature Controller may be
damaged.
