NOTES
●Mounting Attention
1.When installing the relay, always use washers to prevent the screws from loosening.
2.Tighten each screw within the rated range given in the outline dimensions. Exceeding
the maximum torque may result in breakage.
3.Avoid mounting the relay in strong magnetic fields (near a transformer or magnet) or
close to an object that radiates heat.
●Electrical Life Attention
1.This relay is a DC high-voltage 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.
2.Please treat the relay as a product with limited life and replace it when necessary.
3.The contacts of the relay are polarized. Please follow instructions in the connection
schematic when connecting the contacts.
4.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 specifications of conductor.

●Coil Attention
1.Please note that when using a diode, the switching speed may decrease and cause a
reduction in cut-off performance, we recommend installing a surge protector varistor.
2.The pick-up voltage and drop-out voltage will change with ambient temperature,
please use rated voltage to make sure the relay operate reliable. Don’t exceed
maximum coil voltage.
3.The 250A and 300A types have built-in dedicated drive circuit, please drive the coil
with a quick startup (Built-in one-shot pulse generator circuit).
4.After the ON signal enters the 250A and 300A types, automatic coil current switching
occurs after approximately 0.1 seconds.Do not repeatedly turn it OFF within that 0.1
seconds interval, as doing so may damage the relay.
