Safety Precautions
Do not use the product where corrosive or volatile gases are present, there may
occasionally be a risk of explosion.
Usable life of output relay is determined by switch condition. According the actual
usage, use product within its rated load and electrical life expectancy. If using product
beyond its life expectancy, its contacts may become fused or there may be a risk of
fire.
This may occasionally cause electric shock, fire or malfunction. Never disassemble,
repair or modify the product.
This may occasionally cause electric shock, fire or malfunction. Do not allow metal
fragments or lead wire scraps to fall inside this product.
Make sure that the supply voltage and signal connection is correct before power is
supplied, otherwise the product may be damaged.
Do not touch the input terminals or repair the product while power is supplied.This may
cause electric shock.
