To ensure safety, observe the following precautions.

● Wiring

Power supply voltage

Do not use the product with a voltage or current that will even

momentarily exceed the specified voltage or current range.

Applying a voltage or current exceeding the specified voltage or

current range or using an AC power supply may result in rupture or

burning.

Load Short-circuit

Do not short-circuit the load. Rupture or burning may occur.

Faulty Wiring

Do not miswire such as the polarity of the power supply voltage.

Rupture or burning may occur.

Example 1. Wrong polarity

Example 2. Wrong polarity and faulty wiring

Connection without Load

If the power supply is connected directly without a load, rupture or

burning of the internal elements may occur. Connect a load when

wiring.
