SAFETY STANDARDS
NOTES
1. When installing the relay, always
use washers to prevent the screws
from loosening.
Tighten each screw within the rated
range given below. Exceeding the
maximum torque may result in breakage.
Mounting is possible in either direction.
• M5 screw (80A and 300A main unit
• M4 screw (10A PC board type main unit
Recommended securing torque on load
side terminals
• 80A/M5 bolt: 3.5 to 6.5 N·m
• 300A/M8 bolt: 10 to 12 N·m
2. The contacts of the relay are
polarized. Please follow instructions
in the connection schematic when
connecting the contacts.
We recommend installing a surge
protector varistor (ZNR) for the 10A and
80A types. Avoid using a diode as this
may result in decreased cut-off capability.
3. Do not use a relay if it has been
dropped.
4. Avoid mounting the relay in strong
magnetic fields (near a transformer or
magnet) or close to an object that
radiates heat.
5. 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 and from the
point of view of safety, consider installing
a failsafe circuit in the device.
Also, in order to avoid increased contact
resistance, do not operate when there is
no switching load.
6. 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 flow of electrical
current). For this reason, make sure the
For Cautions for Use.

ambient operating temperature is
between –40 and 80 C
and the ambient storage temperature is
between –40 and 85 C
7. Do not disassemble the relay.
Please note that disassembling the
relay will invalidate the warranty.
8. 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.
9. Coil operating power
Pure DC current should be applied to the
coil. The wave form should be
rectangular. 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.
10. Don’t exceed maximum coil
voltage. Exceeding maximum
allowable coil voltage on continuous
basis will damage the relay and could
case failure.
11. Ensure that the rated contacts
voltage and current values are not
exceeded.
12. The rated control capacity and life
are given as general guides.
The contact life is heavily influenced by
the type of load and other related
conditions, and these factors must be
kept in consideration when using the
relay.
13. 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.
14. 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: Faston terminal for #187
• 80A type: Min. 15mm
• 300A type: Min. 100mm
15. Use 40N to 70N of force as a guide
to fasten the terminal connected to the
10A TM type. Please use caution when
inserting or removing the terminal as
the relay tab terminal may cause
injuly.
16. 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 flux overflow
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
• Solder time: within approx. 5 seconds
17. Make sure the power is turned off
when wiring.
18. Incorrect wiring may cause
unexpected malfunction and failure.
19. 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.
Confirm electrical life using actual
load. In the case of DC cut-off, please
note the contact polarity.
20. 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).
21. 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 10N.
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.
