5.2. Safety Cautions
These specifications are intended to preserve the quality assurance of products and individual components.
Before use, check and evaluate the operation when mounted on your products.
Abide by these specifications without deviation when using the products.
These products may short-circuit. If electrical shocks, smoke, fire, and/or accidents involving human life are anticipated
when a short circuit occurs, provide the following failsafe functions as a minimum:
1. Ensure the safety of the whole system by installing a protection circuit and a protection device.
2. Ensure the safety of the whole system by installing a redundant circuit or another system to prevent a single fault
causing an unsafe status.
