3Application Precautions
xii
1 General Safety Precautions
WARNING Do not attempt to disassemble, apply pressure, distort, subject to temperatures
of 100°C or more, or throw the E5ZE into fire. A lithium battery is built into the
E5ZE and any attempt to any of the above may result in fire, explosion, or
combustion.
WARNING Do not attempt to disassemble, modify, or repair the E5ZE. Any attempt to do so
may result in malfunction, fire, or electric shock.
Caution Do not use any terminal that is marked “Don’t use.”
2 Operating Environment Precautions
Caution Be sure to check polarity when connecting the terminals.
Caution Do not install power lines or high-tension lines alongside lines connected to the
E5ZE to prevent the E5ZE from being influenced by inductive noise. Install lines
connected to the E5ZE through an independent conduit or use a shielded cable
for the lines to protect them from inductive noise.
Caution Separate the E5ZE from devices generating a strong high-frequency, such as
high-frequency welding machines, or devices that generate surge.
Caution Do not operate the E5ZE in the following locations:
•Locations subject to exposure to water, oil, or chemicals.
•Locations subject to corrosive or flammable gases.
•Locations subject to temperatures or humidity outside the range specified in
the specifications.
•Locations subject to condensation.
•Locations subject to shock or vibration.
•Locations subject to severe changes in temperature.
•Locations subject to icing.
Caution Do not install the E5ZE in a location with obstructions preventing radiant heat
from escaping.
3 Application Precautions
WARNING Make sure that no metal particles or wire chips are accidentally left in the
product. Doing so may result in malfunction, fire, or electric shock.
WARNING Install a separate alarm to prevent the temperature from increasing excessively
if the E5ZE malfunctions. Insufficient safety precautions may cause serious
accidents if the temperature control malfunctions.

3Application Precautions
xiii
Caution Tighten the screws on the terminal block to the torque specified in the manual.
Loose screws may result in burning or malfunction.
Caution Do not connect loads to the E5ZE that exceed the specified ratings. Excessively
large loads may result in malfunction or burning.
Caution Always use the power supply voltage specified in the manual. An incorrect volt-
age may result in malfunction or burning.
Caution Confirm that no adverse effects will occur in the system before attempting to per-
form a hardware test. Insufficient confirmation may result in unexpected opera-
tions.
Caution Make sure that all the E5ZE set values are suitable for the controlled system.
Unsuitable set values may result in unexpected operations causing damage to
the product or accidents.
