EP (AEP)
7. Permeation life of internal gas
This relay uses a hermetically encased
contact (capsule contact) with gas inside.
The gas has a permeation life that is
affected by the temperature inside the
capsule contact (ambient temperature +
temperature rise due to ?ow of electrical
current). Therefore, please do not exceed
the operation ambient and storage
ambient temperatures given in the
speci?cations.
8. Do not disassemble the relay.
Please note that disassembling the
relay will invalidate the warranty.
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 ?ow, and applying a coil
voltage higher than the rated
operating voltage.
10. Pure DC current should be applied
to the coil. If it includes ripple, the
ripple factor should be less than 5%.
However, check the actual circuit
since the characteristics may be
slightly different. The power supply
waveform supplied to the coil should
be rectangular. Also, the 300A type
has a built-in dedicated drive circuit. It
may not operate normally unless the
rise time is 10 ms or less.
11. Don’t exceed maximum coil
voltage. Exceeding maximum
allowable coil voltage on continuous
basis will damage the relay and could
case failure.
12. If you will be using with a load
voltage that exceeds 400 V DC, please
be sure to verify operation on the
actual device, referring to the
switching life curves (reference data).
You must absolutely avoid continual
use in which the load current exceeds
the rated value. This will cause
abnormal heating.
13. The rated control capacity and life
are given as general guides.
It is important to conduct suf?cient tests
on the actual device, because contact
properties and working life will differ
considerably depending on the type of
load and conditions.
14. Main contact ratings in the ratings
apply to when there is a resistive load.
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.
In order to prevent contact welding
when using a capacitive load (C load)
such as a capacitor load, please make
the inrush current setting more than
two times that of the nominal current.
Please contact us for more
information.
15. Be careful that foreign matter and
oils and fats kind don’t stick to the
main terminal parts because it is likely
to cause terminal parts to give off
unusual heat. Also, please use the
following materials for connected
harnesses and bus bars.
10A TM type:
#187, 0.5 mm board thickness
20A TM type:
#250, 0.8 mm board thickness
tab terminal (JIS C289-1999 compliant,
?at type connection terminal)
Harness nominal cross-sectional area
Load input terminal side;
10A TM type: min. 2.0 mm 2
20A TM type: min. 3.0 mm 2
Coil input terminal side;
10A and 20A TM types: min. 0.3 mm 2
80A type: min. 15 mm 2
200A type: min. 60 mm 2
300A type: min. 100 mm 2
16. Use 40 to 70N or 50 to 80N of force
as a guide to fasten the terminal
connected to the 10A TM and 20A TM
types. Please use caution when
inserting or removing the terminal as
the relay tab terminal may cause
injuly. Also, unstable conductivity and
abnormal terminal heating may occur;
therefore, please check that there is
no deformation of or foreign objects
on the faston terminals (blade
receptacle) you will be connecting.
Use JIS C2809 (or IEC60760) certi?ed
products.
17. Place the PC board mount type
(10A PC board type) securely by hand
soldering after attaching it using M4
screw. Don’t submerge assembled
board in cleaning solvent or water.
Also, be careful not let ?ux over?ow
up from the PC board or adhere to the
base of the relay.
Recommended hand soldering
conditions
? Soldering iron: 30 to 60 W
? Tip temperature: 400 ° C 752 ° F
? Solder time: within approx. 5 seconds
18. Make sure the power is turned off
when wiring.
19. Incorrect wiring may cause
unexpected malfunction and failure.
20. Regarding AC cutoff, although
there is no contact polarity, generally
it is thought that the electrical life will
shorten due to cutoff in the reverse
direction, compared to DC cutoff.
Con?rm electrical life using actual
load. In the case of DC cut-off, please
note the contact polarity.
21. Lead-free solder (tin, silver and
copper) is used as pre-solder for the
terminals of the PC board mount type
(10A PC board type).
22. The warranted tensile strength of
the female connector lead wire used
for connection that comes with the
80A and 300A connector type when
attaching it to the relay body is 98N.
Avoid excessive tension as this is a
cause of broken wires and damage.
Also, insert the female connector
deeply and make sure the connection
is secure.
23. Condensation will occur during
sudden temperature changes in hot
and humid environments. Caution is
required, because condensation will
cause a decrease in the insulation
resistance between the terminals.
