在DIN导轨上安装任何处理器单元或通信接口之前，
仔细阅读随设备提供的安装说明。
要将PM891装置安装在DIN导轨上，请使用刀片螺丝刀将其牢固地安装到
需要装置锁紧螺钉（1 mm槽）。有关单元锁定的详细信息，请参阅
螺钉，参见第71页图20。
将PM891装置安装在DIN导轨上：
1.将锁定装置旋转至打开位置（1），将上唇钩在
装置后部牢固地位于DIN导轨的上边缘，并轻轻地卡入
装置完全进入安装位置。
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）。PM891装置现在完全锁定在
定位并与DIN导轨有良好的接地连接。
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。

拆除带有底板的处理器单元
使用以下步骤拆卸装置，包括底板：
1.关闭或断开控制器单元的电源。
2.从适当的装置底板上拆下任何可拆卸电缆。

3.将锁定装置旋转到单元基板上的滑动位置（2），
参见第69页的图17。
4.轻轻地从侧面松开装置/底板，以释放
正在拆除装置底板。
5.逆时针转动锁紧装置至打开位置（1），并松开
装置底板在底座处向外和向上。提起装置，将其从
DIN导轨。AC 800M装置必须与电源断开连接
然后将其从DIN导轨上拆下。
为了提供足够的进入和拆卸空间，请注意，滑块
必须在与装置相邻的装置基板上执行顺序，即：
将被移除。
通过轻轻撬动，装置底板可以轻松地彼此断开
用一字螺丝刀将它们分开（参见第74页图23）

Before mounting any processor unit or communication interface on the DIN-rail,
read carefully the installation instructions provided with the equipment.
To mount the PM891 unit on the DIN-rail, a blade screwdriver that fits securely into
the unit locking screw (1 mm slot) is required. For details about the unit locking
screw, see Figure 20 on page 71.
To mount the PM891 unit on the DIN-rail:
1. Rotate the locking device to the OPEN position (1), hook the upper lip at the
rear of the unit securely over the upper edge of the DIN-rail, and gently snap
the unit 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.
Figure 19. AC 800M Controller (except PM891) – Side View
To prevent damage to the pins, ensure that the baseplate plugs and sockets are
fully aligned as the units interconnect. Do not apply excessive force.

3. When the interconnection is complete, rotate the locking device clockwise to
the LOCKED position (3). The PM891 unit is now fully locked into the
position and has a good ground connection to the DIN-rail.
It is essential that the locking device be placed in the LOCKED position to
avoid possible problems caused by vibration and/or intermittent grounding.

Removing Processor Units Complete with Baseplates
Use the following procedure to remove a unit, complete with baseplate:
1. Switch off or disconnect the power supply to the controller units.
2. Remove any detachable cables from the appropriate unit baseplate.
Figure 22. PM891 - Side view
AC 800M units must be disconnected from the power source before removing
them from a DIN-rail!
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.

3. Rotate the locking device to the SLIDE position (2) on the unit baseplate,
see Figure 17 on page 69.
4. Gently ease the unit/baseplates sideways in order to release the contacts of the
unit baseplate being removed.
5. Turn the locking device anti-clockwise to the OPEN position (1) and ease the
unit baseplate outward and upward at the base. Lift the unit to remove it from
the DIN-rail. The AC 800M units must be disconnected from the power source
before removing them from the DIN-rail.
In order to provide adequate access and removal space, note that the SLIDE
sequence must be carried out on the unit baseplates adjacent to the unit that is
to be removed.
The unit baseplates are easily disconnected from each other by gently prying
them apart with a blade screwdriver (see Figure 23 on page 74)
