Coil Attention

When installing the relay, always use washers to prevent the screws from loosening.

.Tighten each screw within the rated range given

. Exceeding

the maximum torque may result in breakage.

Avoid mounting the relay in strong magnetic fields (near a transformer or magnet) or

close to an object that radiates heat.

.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.

.Please treat the relay as a product with limited life and replace it when necessary.

.The contacts of the relay are polarized. Please follow instructions in the connection

schematic when connecting the contacts

.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

.Please note that when using a diode, the switching speed may decrease and cause a

reduction in cut-off performance,

e recommend installing a surge protector varistor.

drive the coil

with a quick startup (Built-in one-shot pulse generator circuit).

.After the ON signal enters the

300A type , 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.
