WARNING
This product is not designed or rated for ensuring safety
of persons.
Do not use it for such purposes.
Item Examples
Power supply
Do not impose an excessive voltage on the
E2E, otherwise it may explode or burn. Do
not impose 100 VAC on any E2E DC Model,
otherwise it may explode or burn.
Load short-circuit
Do not short-circuit the load, or the E2E may
explode or burn.
The E2E short-circuit protection function is
valid if the polarity of the supply voltage im-
posed is correct and within the rated voltage
range.
Wiring
Be sure to wire the E2E and load correctly,
otherwise it may explode or burn.
Connection with no load
Make sure to connect a proper load to the
E2E in operation, otherwise it may explode or
burn.

(Load short-circuit)
The following diagram shows that the load is
short-circuited while the polarity of the supply
voltage imposed on the E2E/E2E2 is wrong,
in which case the E2E/E2E2 may explode or
burn.
