Notes:

#1 This value can change due to the switching frequency, environmental conditions,

and desired reliability level, therefore it is recommended to check this with the

actual load.

#2 When using a surge absorbing element for the relay coil drive circuit, please use

with a surge absorbing element with a clamp voltage of 1.5 to 2.0 times the rated

operating voltage. When the coil is connected in parallel with a diode, resistor or

capacitor, the release time will delay which might lead to degradation in shutoff

performance and electrical life.

Contact terminals have polarity; therefore, please obey the wiring diagram when

connecting contacts.

The electrical load performance value applies when a varistor is connected in

parallel with the coil.

1. To ensure proper operation, the

voltage applied to the coil should be

the rated operating voltage of the coil.

Also, be aware that the pick-up and

drop-out voltages will ﬂuctuate

depending on the ambient

temperature and operating conditions.

2. Heat, smoke, and even a ﬁre may

occur if the relay is used in conditions

outside of the allowable ranges for the

coil ratings, contact ratings, operating

cycle lifetime, and other

speciﬁcations. Therefore, do not use

the relay if these ratings are exceeded.

3. If the relay has been dropped, the

appearance and characteristics

should always be checked before use.

4. This relay is for DC loads. Do not

use it for AC load switching.

5. Make sure that the relay is wired

correctly. Incorrect wiring may cause

unexpected events or the generation

of heat or ﬂames.

6. We recommend you use a surge

absorbing element with a clamp

voltage of 1.5 to 2.0 times the rated

operating voltage for the relay coil

drive circuit as a means for relay coil

surge absorption. Please avoid the

use of diodes, capacitors and

resistors because they lead to

degradation in cut-off performance.

7. Avoid mounting the relay in strong

magnetic ﬁelds (near a transformer or

magnet) or close to an object that

radiates heat.

8. Electrical life

This relay is a high-voltage direct-current

switch. In its ﬁnal breakdown mode, it

may lose the ability to provide the proper

cut-off. Therefore, do not exceed the

indicated switching capacity and life.

(Please treat the relay as a product with

limited life and replace it when

necessary.)

In the event that the relay loses cut-off

ability, there is a possibility that burning

may spread to surrounding parts, so

conﬁgure the layout so that the power is

turned off within one second.

9. If the power is turned off and then

immediately on after applying the

rated voltage (current) continuously to

the relay’s coil and contact, the

resistance of the coil will increase due

to a rise in the coil temperature. This

causes the pick-up voltage to rise, and

possibly exceed the rated pick-up

voltage. In these circumstances, take

measures such as reducing the load

current, limiting the duration of

current ﬂow, and applying a coil

voltage higher than the rated

operating voltage (quick start).

10. If you are using an inductive load

(L load) such that L/R > 1 ms, add

surge protection in parallel with the

inductive load. If this is not done, the

electrical life will decrease and cut-off

failure may occur.

11. Be careful that foreign matter and

oils and fats kind doesn’t stick to the

main terminal part because it is likely

to cause a terminal part to give off

unusual heat.

12. Avoid excessive load applied to

the terminal in case of installing such

as a bus bar etc., because it might

give bad inﬂuence to the opening and

closing performance.

Tighten each of the screws within the

rated ranges given below.

Main terminal (M6 screw):

6.0N·m to 8.0N·m

Main unit mounting (M5 screw):

2.5N·m to 3.6N·m

EJ (AEJ)

13. Usage, transport and storage

conditions

Ambient temperature, humidity, and

atmospheric pressure during usage,

transport, and storage of the relay:

1) Temperature: –40 to +85°C –40 to

+185°F

2) Humidity: 5 to 85% RH

(Avoid freezing and condensation.)

3) Atmospheric pressure: 85 to 106 kPa

Temperature and humidity range for

usage, transport, and storage:

4) Condensation

Condensation forms when there is a

sudden change in temperature under

high temperature and high humidity

conditions. Condensation will cause

deterioration of the relay insulation.

5) Freezing

Condensation or other moisture may

freeze on the relay when the

temperatures is lower than 0°C 32°F.

This causes problems such as sticking of

movable parts or operational time lags.

6) Low temperature, low humidity

environments

The plastic becomes brittle if the relay is

exposed to a low temperature, low

humidity environment for long periods of

time.
