安全措施

任何安装、接线、测试和维修的执行都必须符合所有当地和全国性的电气规范。

危险
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Apply appropriate Personal Protective Equipment (PPE) and follow safe electrical work practices. See NFPA 70E, CSA Z462 or other local standards. Turn off all power supplying this device and the equipment in which it is installed before working on or in the equipment. Always use a properly rated voltage sensing device to confirm that all power is off. Follow guidelines in the Wiring section of the related Installation Sheet. Assume communications and I/O wiring are hazardous live until determined otherwise. Do not exceed the maximum ratings of this device. Do not short secondary terminals of Voltage Transformer (VT). Do not open secondary terminals of Current Transformer (CT). Ground secondary circuit of CTs. Do not use the data from the meter to confirm power is off. Replace all devices, doors and covers before turning on power to this equipment. Do not install CTs or LPCTs in equipment where they exceed 75% of the wiring space of any cross-sectional area in the equipment. Do not install CTs or LPCTs in areas where ventilation openings may be blocked or in areas of breaker arc venting. Secure CT or LPCT secondary conductors to ensure they do not contact live circuits. Use copper conductors only. 请勿使用水或任何液体材料清洁产品。使用清洁布清除污垢。如果污垢无法清除，请联系当地技术支持代表。安装前，请验证电源侧过流保护设备的额定值和特性。请勿超过测量仪的额定最大电流或电压。未按说明操作将导致人身伤亡等严重后果。

未按说明操作将导致人身伤亡等严重后果。

注: See IEC 60950-1 for more information on communications and I/O wiring connected to multiple devices.

警告
Unintended Operation Do not use this device for critical control or protection of persons, animals, property or equipment. 未按说明操作可能导致人身伤亡或设备损坏等严重后果。

警告
Potential compromise of system availability, integrity, and confidentiality Change default passwords/passcodes/PIN codes to help prevent unauthorized access to device settings and information. Disable unused ports/services and default accounts, where possible, to minimize pathways for malicious attacks. Place networked devices behind multiple layers of cyber defenses (such as firewalls, network segmentation, and network intrusion detection and protection). Use cybersecurity best practices (for example: least privilege, separation of duties) to help prevent unauthorized exposure, loss, modification of data and logs, interruption of services, or unintended operation. 未按说明操作可能导致人身伤亡或设备损坏等严重后果。
