can occur.
Indicates situations where slight bodily injury or minor equipment damage can
occur.
Indicates actions or procedures that should NOT be performed.
Indicates actions or procedures that MUST be performed to ensure correct unit
operation.
Be sure to design your system so that a communication fault between the PS-B and its host controller will
not cause equipment to malfunction. This is to prevent any possibility of bodily injury or equipment
damage.
Do not use the PS-B with aircraft control devices, aerospace equipment, central trunk data transmission
(communication) devices, nuclear power control devices, or medical life support equipment, due to these
devices’ inherent requirements of extremely high levels of safety and reliability.
When using the PS-B with transportation vehicles (trains, cars, and ships), disaster and crime prevention
devices, various types of safety equipment, and medical devices that are not life-support related, use
redundant and/or failsafe system designs to ensure proper reliability and safety.
Do not disassemble or modify the PS-B unit. Doing so may cause a fire or an electric shock.
Do not operate the PS-B in an environment where flammable gases are present, since it may cause an
explosion.
