注：安装支架最多可接受直径为10mm的螺钉。
（5） 使用适当的安装螺钉将机柜固定到位。
（6） 安装System 57机架和AC至DC电源单元（如果所需）插入所示位置的机柜中。
（7） 将电缆穿过与现场接线板相邻的压盖，在可能的情况下，保持传感器电缆与其他接线。
（8） 准备并将电缆端连接至现场接口和继电器卡终端留有足够的电缆长度，以便机架如果未来需要扩展，则撤回。用于终端标识见第2章。
（9） 确保机柜通过连接适当的接地电缆至位于底部面板中的接地螺柱内阁
（10） 关闭并锁定机柜。
注意安全
在调试之前，不要向系统57通电已阅读并理解程序。参见第5节面板安装
所有机架和交流至直流电源装置均适用于面板安装和安装如下：
（1） 切出合适的孔以容纳System 57机架以及使用尺寸的电源装置（如需要）
展示：尺寸为（mm）的机架台将机架插入孔中，并使用M6或类似工具固定螺栓，穿过前法兰上的四个安装孔盘子。
（3） 确保后检修架后部有足够的支撑。
（4） 准备并将电缆端连接至现场接口和继电器卡和终端。终端标识见第2章，其中可以将传感器电缆与其他接线分开。
（5） 确保机架通过连接适当的接地电缆至机架后部的接地螺柱。机架安装
16路3U高后通道和6U高前通道机架为：
适用于安装在标准19英寸（483mm）宽的安装框架中。
其安装如下：
（1） 将机架插入19”安装框架，并使用M6或
穿过前部四个安装孔的类似螺栓法兰盘。
（2） 确保后检修架后部有足够的支撑。
（3） 准备并将电缆端连接至现场接口和继电器卡终端。终端标识见第2章，其中可以将传感器电缆与其他接线分开。
（4） 确保机架通过连接适当的接地电缆至机架后部的接地螺柱。
Note: The mounting brackets will accept up to a 10mm diameter screw.
(5) Secure the cabinet in position using appropriate mounting screws.
(6) Fit the System 57 Rack and AC to DC Power Supply Unit (if
required) into the cabinet in the positions shown.
(7) Pass cables through the gland adjacent to field terminal blocks,
where possible keeping the sensor cable(s) separate from the
other wiring.
(8) Prepare and connect the cable ends to Field Interface and Relay
Card terminals leaving sufficient cable length to allow for the rack to
be withdrawn if future expansion is required. For terminal
identification see Chapter 2.
(9) Ensure that the cabinet is properly earthed by connecting a suitable
earth cable to the earth stud located in the bottom panel of the
cabinet.
(10) Close and lock the cabinet.
CAUTION
Do not apply power to the System 57 until the commissioning
procedure has been read and understood. See Section 5.PANEL INSTALLATION
All racks and the AC to DC Power Supply Units are suitable for panel
installation and are installed as follows:
(1) Cut out a suitable aperture to accommodate the System 57 rack
and power supply unit (where required) using the dimensions
shown:
Rack Table of Sizes (mm)Insert the rack into the aperture and secure using M6, or similar
bolts, through the four mounting holes located upon the front flange
plates.
(3) Ensure adequate support at the rear of rear access racks.
(4) Prepare and connect the cable ends to Field Interface and Relay
Cards terminals. For terminal identification see Chapter 2. Where
possible keep sensor cables separate from the other wiring.
(5) Ensure that the rack is properly earthed by connecting a suitable
earth cable to the earth stud located at the rear of the rack.
RACK INSTALLATION
The 16-way 3U high rear access and 6U high front access racks are
suitable for mounting in standard 19" (483mm) wide Mounting Frames.
These are fitted as follows:
(1) Insert the rack into the 19" Mounting Frame and secure using M6 or
similar bolts through the four mounting holes located on the front
flange plates.
(2) Ensure adequate support at the rear of rear access racks.
(3) Prepare and connect the cable ends to Field Interface and Relay
Card terminals. For terminal identification see Chapter 2. Where
possible keep sensor cables separate from the other wiring.
(4) Ensure that the rack is properly earthed by connecting a suitable
earth cable to the earth stud located at the rear of the rack.
