Matters to Be Observed When Using This Product
Matters to Be Observed When Using This Product
(D-type : E series)
Safety measures
An abnormal state of the D-type / E series varistor (ZNR surge absorber, hereinafter "the product" or "the surge absorber")
that results from a problem with service conditions (materials used, the surrounding environment, power conditions, circuit
conditions, etc.) may cause a fire accident, electric shock accident, burn accident, or product failure. Matters to note when
handling this product will hereinafter be described. What is described below should be checked sufficiently before the
product is used.
■ Confirming rated capabilities
Use the surge absorber within the range of its rated capabilities. Each type of surge absorber has specified rated
capabilities including a maximum allowable circuit voltage, a surge current tolerance, an energy tolerance, an impulse
lifespan (surge lifespan), average pulse power, and a service temperature. Using the surge absorber under severe
service conditions that are beyond the rated capabilities causes degraded performance of the surge absorber or
destruction of a circuit element, which may lead to smoke generation, ignition, etc.
■ Take the following measures in order to avoid an accident caused by expected phenomenon.
(1) Destruction of the surge absorber may scatter its fractured pieces around. To protect other elements from these
pieces, set product in a case or shield it with a cover.
(2) Do not place the surge absorber near combustible materials (vinyl cable, resin mold, etc.). If avoiding the vicinity
of combustible materials is difficult, protect the combustible material with an incombustible cover.
(3) Surge absorber placed between lines
When the surge absorber is placed between lines, connect a normal type current fuse in series with the surge
absorber.
* See "Current fuse" in the "Circuit design and circuit board design" section.
(4) Surge absorber placed between a line and the ground
① When the surge absorber is placed between a line and the ground, even if the surge absorber short-circuits,
ground resistance will remain in the section between the line and the ground, leaving a possibility that the
current fuse won’t blow, in which case the outer sheath resin of the surge absorber may generate smoke or
ignite due to current flow. To prevent such a case, place an earth leakage breaker in a location closer to the
power supply than the surge absorber. When not using an earth leakage breaker, use a current fuse and
temperature fuse in series with each other.
* See Table 1 in the "Circuit design and circuit board design" section.
② When the surge absorber is placed between a live part and a metal case, it may cause electric shock if the
surge absorber short-circuits. To avoid this, ground the metal case or shield it to prevent direct contact with the
metal case.
■ In case the surge absorber should short-circuit and generate smoke or ignite, immediately cut off current flow
to the surge absorber.
■ Rated voltage for UL certification, etc.
To allow the surge absorber to meet leak current requirements, etc., a maximum allowable circuit voltage and rated
voltage are specified for the surge absorber.
When applying for UL certification, etc. of a device equipped with a surge absorber, ensure the working voltage of the
device does not exceed the rated voltage of the surge absorber.
■ An unexpected sharp rise in the working voltage, an incoming excessive surge, etc., may cause the surge absorber to
generate smoke or ignite.
In such a case, fire spreading through the device should be prevented to avoid expanded damage. To achieve this,
take a multi-protection measure, such as adopting fire-resistant materials that make up the outer shell components
and structural materials.
Use environments and cleaning conditions
■ Do not use the surge absorber in an outdoor environment where the surge absorber is exposed to sunlight.
■ Do not use the surge absorber in which direct sunlight hits the surge absorber or near a heating element where the
temperature of the surge absorber would rise above its working temperature.
■ Do not use the surge absorber in a place where the surge absorber is exposed to wind or rain or a highly humid place
where steam is emitted or dew concentrates.

Matters to Be Observed When Using This Product
■ Do not use the surge absorber in a place filled with dust or salt, in an atmosphere contaminated with a corrosive gas,
etc., or in liquids such as water, oil, chemical, or organic solvents.
■ Do not wash the surge absorber with a solvent (thinner, acetone, etc.) that damages the outer sheath resin.
Response to anomalies and handling conditions
Be careful not to drop the surge absorber on the floor, etc. The product is likely to suffer mechanical or electrical damage
when dropped on the floor. Avoid using such a product.
Circuit design and circuit board design
Meet the following requirements. Not following the requirements can result in a shorter lifespan of the surge absorber or its
failure.
■ Choose a surge absorber whose maximum allowable circuit voltage has a margin relative to the maximum voltage range
including source voltage fluctuations.
* See Table 1 in the "Circuit design and circuit board design" section.
■ When surges are applied intermittently to the surge absorber at short intervals (when pulses of voltages are applied in a
noise simulator test, etc.), make sure that the surge power does not exceed the maximum average pulse power of the surge
absorber.
■ The product numbers of recommended surge absorbers to choose are shown in Table 1.
(1) The case of placing the surge absorber between lines
When the source voltage is expected to rise temporarily due to unbalanced single-wire loads in a three-phase three-wire
connection configuration, a short circuit between a voltage line and a neutral line, loss of the neutral line, or resonance of
a capacitive load caused by switching on/off, use a surge absorber (varistor) indicated by "*" in Table 1.
(2) The case of placing the surge absorber between a line and the ground
Line-to-ground voltage may rise with a single-wire ground fault, etc. Use a recommended surge absorber in Table 1 that
is different from the surge absorber placed between lines. When the device is subjected to an insulation resistance test
(500 V DC), use a D-type surge absorber indicated by "**" in Table 1.
According to "Electrical Appliance Technical Standards" based on the Electrical Appliance and Material Safety Act, when
using a varistor voltage which would fail the insulation performance test, the surge absorber may be removed from the
device when being subjected to the test, depending on circuit test conditions.
* See attached table 4, appendix 4, "Electrical Appliance Technical Standards" based on the Electrical Appliance and
Material Safety Act.
■ Current fuse
(1) Select a surge absorber and the rated current for a current fuse to be used in a manner shown in the following table.
Confirm that no secondary accident arises when the surge absorber in an actual circuit breaks. Selected rated currents of
current fuses shown in the following table are exemplary one and may vary depending on circuit conditions used. Confirm
the rated current by a test, etc., before using the current fuse.

Matters to Be Observed When Using This Product
Processing conditions
■ Do not apply vibration, impact (drop impact, etc.), or pressure strong enough to crack the outer sheath resin or absorber
body of the surge absorber.
■ When coating the surge absorber with a resin or embedding it in a resin mold, avoid using a resin that degrades the
surge absorber.
■ Do not bend or apply a force to the lead of a D-type surge absorber close to the outer sheath resin.
Mounting and storage conditions
■ When soldering the surge absorber, follow recommended soldering conditions shown in the following table so that
solder or the insulation material making up the surge absorber is not melted.
■ When making holes for mounting the surge absorber on the board, check the dimensions of the holes on the board,
referencing the central point of the interval between the leads.
Because the overall dimensional tolerance is large, forming the holes with high precision requires careful processing.
