PM8xx和CI8xx装置的安装程序，包括底板
在将任何处理器单元或通信接口安装到DIN导轨上之前，
仔细阅读随设备提供的安装说明。自从
电子单元和基板作为一个单元提供，无需
在安装过程中将它们分开。
将装置安装到DIN导轨上只需要一个合适的刀片螺丝刀
牢固地插入底板锁紧螺钉（1 mm槽）。有关详细信息，请参阅
安装程序，参见第69页图17。
使用以下步骤安装底板，包括单元：
1.将锁定装置旋转至打开位置（1），将上钩钩在
装置底板的后部，牢固地位于DIN导轨的上边缘，以及
轻轻地将底板完全卡入安装位置。
2.将锁定装置旋转至滑动位置（2），沿
DIN导轨至所需安装位置，并使用连接器插头和
插座轻轻地将其连接到相邻的装置底板上。
3.互连完成后，顺时针旋转锁定装置
锁定位置（3）。底板现在完全锁定到位，并且
与DIN导轨有良好的接地连接。

不允许在通电和运行状态下操纵CEX总线底板
系统在更换或移除基板之前，该基板上的所有CEX模块
必须删除段。
为防止损坏引脚，确保基板插头和插座完全
当单元互连时对齐。在任何情况下都不要过度使用武力！
必须将锁定装置置于锁定位置，以便：
避免振动和/或间歇性接地可能导致的问题。

Each module's conductive back plane connects to the metallic DIN-rail which serves
as the module electronics ground conductor between the interconnected devices.
This is to ensure a good ground connection both for the internal logic and for the
EMI immunity and RF emission of the modules. The DIN mounting rail must have a
good bond to the PE of the cabinet.
If AC 800M modules are configured as two or more groups interconnected with
extension cables, special care should be taken to ensure that the DIN-rails of all
groups have a good connection to ground. Also ensure to fix the figure numbers.
Mounting on metal sheet
The DIN-rail shall be firmly attached to an unpainted metal sheet with fastening
screws every 100 mm (4 in) to ensure good mechanical stability and a good chassis
ground connection in the cabinet or an open rack.
The metal sheet shall at least be 2.5 mm thick and at least 180 mm high. The metal
sheet shall be mechanical fastened at least every 500 mm to the cabinet or rack with
a minimum of four screws. The fastening to the cabinet frame shall be performed
with self-tapping screws to get a good grounding connection.

3BSE036351-510 A 67
Prefabricated aluminum profile
There are aluminum profiles for horizontal mounting. The aluminum profile gives
an excellent grounding and rigid mounting of products concerned. The aluminum
profile shall be fastened to the cabinet with at least 4 self-tapping screws.
The profile has grooves for screws that can be used for fastening the modules in an
environment with high vibrations.

Mounting Procedure for PM8xx and CI8xx Units, Complete with Baseplates
Before mounting any processor unit or communication interface onto the DIN-rail,
read carefully the installation instructions provided with the equipment. Since the
electronic unit and baseplate are supplied as a single unit, there is no requirement to
separate them during the mounting procedure.
Mounting the units onto the DIN-rail only requires a blade screwdriver that fits
securely into the baseplate locking screw (1 mm slot). For further details on
mounting procedure, see Figure 17 on page 69.
Use the following procedure to mount the baseplates, complete with units:
1. Rotate the locking device to the OPEN position (1), hook the upper hook at the
rear of the unit baseplate securely over the upper edge of the DIN-rail and
gently snap the baseplate fully into the mounting position.
2. Rotate the locking device to the SLIDE position (2), slide the unit along the
DIN-rail to the desired mounting position and using the connector plugs and
sockets gently attach it to the adjacent unit baseplate.
3. When interconnection is complete, rotate the locking device clockwise to
the LOCKED position (3). The baseplate is now fully locked into position and
has a good ground connection to the DIN-rail.
For further visual information on mounting AC 800M Controller units,
see Figure 18 on page 69.
This topic does not apply to PM891. See Mounting Procedure for PM891 Unit on
page 70.
It is not allowed to manipulate CEX bus baseplates in a powered and running
system. Before changing or removing a baseplate, all CEX modules on that
segment must be removed.
To prevent damage to the pins, be sure the baseplate plugs and sockets are fully
aligned as the units interconnect. Under no circumstances use excessive force!
It is essential that the locking device be placed in the LOCKED position to
avoid possible problems caused by vibration and/or intermittent grounding.
