Unless further agreements should be made with BUYER before the definition of the order, the package units shall be supplied completely with all the electric equipment required for their operation, that is: motors, boxes, connections, cables as well as all the relevant protection, safety devices, alarms, interlocking, drives, signaling devices, earth system, lighting and telephone systems and so on. 除非在发订单前与买方有进一步协议， 成套装置的供货应包括其操作所需的全 部电气设备，包括：电动机、接线箱、连接、电缆及它们相关的保护、安全设 施、报警、连锁、控制器、信号装置，还有接地、照明、等系统。
2.LIMITS OF SUPPLY 供货范围 The battery limits of supply of the electric part of the package unit are considered the incoming terminal panel of the feeding line of 380V LV or 10kV MV, 50Hz electrical energy or of the possible line of 220V.D.C. energy. 成套设备内电气部分供货分界点设在电源进线柜端子处 电源可能是 50Hz 380V LV, 10kV MV 或 220V.D.C Should the necessity of interconnections for interlocks, control and signaling between the package unit and the other parts of the plant arise, all the connections of the package unit concerned in the above said interconnections will be connected with one terminal board or control 2128E-0000-70-121-0001 成套装置通用电气规定 第 4 页 共 24 页 panel included in the supply. 对于成套单元和厂内其它设施的联锁、控制和信号等的内部接线，所有这些接 线都应连接在包括在供货范围内的一面接线盘或控制盘上。
The energy for possible M.V. Electric loads, if required, will arrive at the terminals of the loads themselves (M. V. starters not included in the supply) and the control cables coming from outside will arrive at the control box (included in the supply) closed to the electric equipment. 当有中压电气负荷时，中压电缆将直接接到中压设备本身的端子上（中压起动 器不包括在供货范围内） ，从外部来的控制电缆将接至电气设备旁的控制箱（包 括在供货范围内）上 Terminal box shall be metallic type with inlet threading as follows: 端子箱应为金属型且带螺纹进出线孔，要求如下： - in class 1 area(Zone 1 and 2): as per test certificate - 在 1 类危险区(1 区或 2 区)：按照检验认证要求。
- in class 2 and unclassified area: ISO 7-1 - 在 2 类危险区和非危险区：ISO 7-1 3.CODES AND REGULATIONS 标准和规范 Design, equipment, material and installations shall conform to requirements of the following Standards and codes; 设计、设备、材料和安装应符合下列相关标准规范的要求： - IEC International Electro technical Commission - GB - DL - SH、、SHSG、、HG Classification of hazardous locations shall be made in accordance with the 2128E-0000-70-121-0001 成套装置通用电气规定 第 5 页 共 24 页 following standards: 危险场所的划分应符合下列标准： - IEC 60079.10 For classification of hazardous area. - NFPA497A For extent of class I hazardous area. - NFPA497B For extent of class II hazardous area. - NFPA497M For classification of gases, vapors and dusts. The selection of equipment and material to be installed in classified areas shall be made in accordance with IEC60079-14 (Proposal 31J26 dated April 1993 to revise IEC60079-14 will be also applied). 安装在危险区的设备和材料的选择应符合 IEC60079-14 的要求（还应符合 1993 年四月的建议书 31J26 对于 IEC60079-14 的修改）和相关国标及行业标准的要 求。
