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 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. 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. When using the 150 A type, mount

it as far away as possible from

Wireless transmitters or devices that

may generate large surges. To prevent

malfunctioning due to high emission

levels, it may be neccessary to take

measures for E.M.I., such as adding a

line noise filter or an electromagnetic

shield.

15. A slight amount of superimposed

line noise may be generated in the

input line the coil current control. It is

recommended to install a line filter to

reduce or eliminate this noise.

16. Ensure that the main terminals are

clean from oils and other foreign

matters. Contamination is likely to

cause increase in the terminal's

temperature.

• 150A type: nominal cross sectional

• 60A type: nominal cross sectional area:

• 10A TM type: Faston terminal for #187

tab terminal, 0.5 mm board thickness

(JIS C2809-1992 compliant, flat type

connection terminal)

Harness nominal cross sectional area

17. Avoid excessive stress on the

terminals. Excessive stress can effect

the performance of the contact

operation.

• M8 screw terminal (150A main terminal

part)

Terminal pulling up strength ; Max.100N

per terminal

The up-down rotation torque applied to

the terminal ; Max.15N• m

18. 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.

19. Place the PCB mount type (10A

PCB type) securely by hand soldering

after attaching it. Don't submerge

assembled board in cleaning solution

or water. Also, be careful not let flux

overflow up from the PCB or adhere to

the base of the relay.

20. Make sure the power is turned off

when wiring.

21. Incorrect wiring may cause

unexpected malfunction and failure.

22. For AC cut-off, there is no contact

polarity. Confirm electrical life using

actual load. In the case of DC cut-off,

please note the contact polarity.

23. Lead-free solder (tin, silver and

copper) is used as the spare solder for

the terminals of the PCB mount type

(10A PCB type).
