1.5. Safety Recommendations

1.5.1. Local regulations

Verify that the use of this product is permitted in the country intended and in the

required product environment.

The use of this product may be dangerous and thus must be avoided where:

Interfacing with other electronic devices in environments such as hospitals,

airports, etc. is a concern.

A risk of explosion exists, such as in the proximity of gasoline, oil refineries,

etc.

CC864-DUAL Hardware User Guide

1vv0300791 Rev 4.4 – 2011-01-26

The integrator is responsible for enforcing local and specific environmental

regulations on the product. For further details refer to Chapter 1.7 for related

documents.

1.5.2. Wiring and Installation

Always follow the instructions in this guide when wiring the product.

The module must be supplied with a stabilized voltage source, and the wiring must

conform to security and fire prevention regulations.

The installation of external components must be well designed in order to ensure the

proper functioning of the module.

1.5.3. Electrostatic Discharge

Avoid any contact with the pins because electrostatic discharge can damage the

product.
