Damage

Indicates a potentially hazardous situation which could result in death or serious injury and/or a
fault in the user’s system if the product is not used correctly.

Before performing any operation described in this manual, turn off all the power supplies to the
system.

Performing such an operation with the power on may cause an electric shock or device fault.

Once the product has been turned on, do not touch any metal part of it.
Doing so may cause an electric shock or device fault.

Indicates the presence of a hazard that may cause a minor or moderate injury, damages to this
product or devices connected to it, or may cause to lose software resources and other properties
such as data, if the device is not used appropriately.

Before moving the product, be sure to turn off all the power supplies and unplug the cables. Watch
your step when carrying the product. Do not use the product in an unstable location such as a
place exposed to strong vibration or a sloping surface. Doing so may cause the product to fall,
resulting in an injury or fault.

The product contains sharp edges that are left unavoidably exposed, such as jumper plugs.
Handle the product with due care not to get injured with such pointed parts.

Do not place anything on the product or expose the product to physical shocks. Do not carry the
product after the power has been turned on.

Doing so may cause a malfunction due to overloading or shock.
Sinc e the product contains many electronic components, keep it away from direct sunlight, high

temperature, and high humidity to prevent condensation. Do not use or store the product where it
is exposed to much dust or a strong magnetic or electric field for an extended period of time.
Inappropriate operating or storage environments may cause a fault.

Use the product within the ranges given in the specifications.
Operation over the specified ranges may cause a fault.

To prevent electrostatic breakdown, do not let your finger or other object come into contact with the
metal parts of any of the connectors. Before handling the product, touch a metal object (such as a
door knob) to discharge any static electricity from your body.

MB39C031-EVBSK-01 2ch Buck DC/DC + LDO Evaluation Board Operation Guide, Doc. No. 002-08724 Rev. *B 4

Cautions

When turning the power on or off, follow the relevant procedure as described in this document.

Damage

Damage

Damage

Before turning the power on, in particular, be sure to finish making all the required connections.
Furthermore, be sure to configure and use the product by following the instructions given in this
document. Using the product incorrectly or inappropriately may cause a fault.

Always turn the power off before connecting or disconnecting any cables from the product. When
unplugging a cable, unplug the cable by holding the connector part without pulling on the cable
itself. Pulling the cable itself or bending it may expose or disconnect the cable core, resulting in a
fault.

Because the product has no casing, it is recommended that it be stored in the original packaging.
Transporting the product may cause a damage or fault. Therefore, keep the packaging materials
and use them when re-shipping the product.
