NEBS 认证—电气安全
Electrical Safety Criteria of the NEBS Authentication
摘要 电气安全要求目的是限制加在网络设备电路和储能部件的电压和电流,保护人体免受伤害,控制来自设备暴露表面的漏电流。介绍了NEBS认证对设备裸露表面感应漏电流的控制、各种电压可达性的限制要求,以及加在通信线缆上源功率的限制。

Abstract Electrical Safety criteria are intended to protect persons from harm by limiting
the voltage and currents that are intentionally applied to communication circuits and to
energized parts of network equipment. The part of concern in NEBS authentication are
to control leakage currents that may be conducted from exposed surfaces of the
equipment .and to restrict access to various levels. An overall power limitation is
imposed on sources that may be applied to communication wiring.
Keywords network equipment building system;electrical safety;classification of
voltages;accessibility;leakage current
