激光行业中及一些高精度需求的行业中关于硬件的介绍，包括软件的一些编译D A N G E R : This product contains potentially lethal voltages. To reduce the possibility of
electrical shock, bodily injury, or death the following precautions must be followed.
1. Disconnect electrical power before servicing equipment.
2. Disconnect electrical power before performing any wiring.
3. Access to the Ndrive CP and component parts must be restricted while connected to a
power source.
4. To minimize the possibility of electrical shock and bodily injury, extreme care must be
exercised when any electrical circuits are in use. Suitable precautions and protection must
be provided to warn and prevent persons from making contact with live circuits.
5. Install the Ndrive CP inside a rack or enclosure.
6. The shunt resistor temperature can exceed 70°C during normal operation and contains
lethal voltage on its terminals and surface. It must be properly enclosed and shielded to
avoid risk of fire and operator shock.
7. Do not connect or disconnect any electrical components or connecting cables while
connected to a power source.
8. All components must be properly grounded in accordance with local electrical safety
requirements.
9. Operator safeguarding
