电缆不得扭曲、拉伸、压碎或弯曲。仅使用符合电缆规格的电缆。在确定电缆的适用性时，应考虑以下因素： 适用于拖链应用 温度范围 耐化学性 室外安装 地下安装连接屏蔽屏蔽连接可能性： 电机电缆：电机电缆屏蔽固定在设备底部的屏蔽夹中。 其他电缆：屏蔽与设备底部的屏蔽连接相连。 备选方案：例如，通过屏蔽夹和导轨连接屏蔽。等电位连接导体的电位差可能导致电缆屏蔽上的电流过大。使用等电位连接导体减少电缆屏蔽上的电流。等电位连接导体的额定电流必须为大电流。1） 如果连接到等电位接地层，则允许多点接地，该接地层的尺寸有助于避免在电力系统短路电流的情况下损坏电缆屏蔽。导线横截面根据安装方法，以下章节描述了两种安装方法的导线横截面： 安装方法B2：导管或电缆槽系统中的电缆 安装方法E：开放式电缆桥架上的电缆注意电缆分组的降额系数和其他环境条件下的修正系数（IEC 60204-1）。警告非预期设备操作 所有快速输入/输出、模拟输入/输出和单点通信信号的接地电缆屏蔽。1)  将通信和输入/输出电缆与电力电缆分开布线。不遵守这些说明可能导致死亡、重伤或设备损坏。根据IEC 60204-1连续运行，横截面以mm2（AWG）为单位，载流量以B2为单位，载流量以A（1）0.75（18）8.5 10.4 1（16）10.1 12.4 1.5（14）13.1 16.1 2.5（12）17.4 22 4（10）23 30 6（8）30 37 10（6）40 52 16（4）54 70 25（2）70 88（1）为单位，铜导线和环境空气温度为40°C（104°F）。更多信息参见IEC 60204-1。该表摘自本标准，还显示了不适用于本产品的电缆横截面。

Cables must not be twisted, stretched, crushed or bent. Use only cables that comply with the cable specification. Consider the following in determining suitability of the cables:  Suitable for drag chain applications  Temperature range  Chemical resistance  Outdoor installation  Underground installation Connecting Shields Shield connection possibilities:  Motor cable: The motor cable shield is fastened in the shield clamp at the bottom of the device.  Other cables: The shields are connected to the shield connection at the bottom of the device.  Alternative: Connect the shield via shield clamps and rail, for example. Equipotential Bonding Conductors Potential differences can result in excessive currents on the cable shields. Use equipotential bonding conductors to reduce currents on the cable shields. The equipotential bonding conductor must be rated for the maximum current. 1) Multipoint grounding is permissible if connections are made to an equipotential ground plane dimensioned to help avoid cable shield damage in the event of power system short-circuit currents. Conductor Cross Sections According to Method of Installation The following sections describe the conductor cross sections for two methods of installation:  Method of installation B2: Cables in conduits or cable trunking systems  Method of installation E: Cables on open cable trays Note the derating factors for grouping of cables and correction factors for other ambient conditions (IEC 60204-1). WARNING UNINTENDED EQUIPMENT OPERATION  Ground cable shields for all fast I/O, analog I/O, and communication signals at a single point. 1)  Route communications and I/O cables separately from power cables. Failure to follow these instructions can result in death, serious injury, or equipment damage.
