在DIN导轨上安装AC 800M装置
由于AC 800M单元（CPU和通信接口）通过自对流冷却，因此它们必须安装在水平DIN导轨上。
每个底板都有一个锁定机构，将金属背板与
DIN导轨，提供有效的接地连接。DIN导轨的功能如下：

The connection shall fulfill the requirements in IEC61131-2 for PE connections,
that is: A conductor which, having a static current of 30 A flowing through,
measures a voltage drop which corresponds to <0.1 ohm.
ABB strongly recommends that the equipment PE-conductor should be of 35 mm2
(2 AWG) cross section if copper lead.

Fusing the External Mains Supply Cable
The recommended fuse rating for the external mains supply of a standard AC 800M
Controller configuration, housed within a floor or wall-mounted cabinet, is given in
Table 3 on page 70.
Should the configuration be other than that stated, instructions for calculating
current consumptions can be found in the relevant I/O manual. For the
AC 800M Controller, see Appendix B, Power Consumption.
Uninterruptable Power Supply
The SD83X series of power supply units comfortably handle the short power
interruptions (<20 milli seconds) that may occur normally within an industrial
environment. Despite this, it is sometimes necessary to protect certain applications
against brief voltage failures by the installation of an Uninterruptable Power Supply
(UPS) device.
The AC 800M controller will shut down safely in the event of a power failure.
During down-time, the application memory and the system clock will be backed up
by the internal battery. In systems subject to long non-operational periods, it is
recommended that an external battery back-up unit be installed. When the power
supply is reconnected, the AC 800M Controller will re-start and run the application
as normal.
If the effects of unexpected shutdowns are not acceptable, it is highly recommended
that the AC 800M Controller be fully protected by connection to an Uninterruptable
Power Supply (UPS) source.
Enclosures
The AC 800M and S800 I/O units hold protection class IP20, with each unit being
individually CE-marked. If a higher IP class is required, an additional enclosure is
needed.

Normally the use of an additional enclosure will not influence the EMC
characteristics of the controller.
Enclosure Mounting
When mounting the controller enclosure, it is important to provide certain minimum
distances between the enclosure, the walls and the ceiling, in order to provide
satisfactory ventilation.
If the enclosure is provided with removable wall cladding, it is important to ensure
that this is not removed from any enclosure adjacent to other enclosures containing
equipment not belonging to the AC 800M Controller and its connected S800 I/O.
ABB Cabinets
As a suitable enclosure, ABB recommends the following two cabinets, both
specially adapted for mounting the AC 800M Controller and S800 I/O. Both are
sealed to protection class IP54 and can support the Controller and S800 I/O units
with no requirement for additional cooling equipment:
• RM550 – Floor-mounted cabinet
• RE820 – Wall-mounted cabinet.
For further information on ABB cabinets, see Appendix C, Recommended
Components.
Mounting AC 800M Units onto DIN-Rail
Since the AC 800M units (CPU and communication interfaces) are cooled by selfconvection, it is important that they only be mounted onto a horizontal DIN- rail.
Each baseplate has a locking mechanism that contacts the metal backplate to the
DIN-rail, providing an effective ground connection. The DIN-rail functions as a
very effective ground for the system.
The additional screw lugs, located in the lower part of the baseplate, serve no
electrical function. They are provided for use should extra fastening be required
within environments subject to excessive vibration.
Mounting on metal sheet Section 2 Installation
72 3BSE036351-600 A
There are two ways of mounting the product in cabinets, open rack or other types of
installations; aluminum profile with mounted DIN-rail or DIN-rail mounted on a
metal sheet of proper size. The aluminum profile or metal sheet shall be properly
connected to protective earth.
DIN-rail type with height 7.5 mm shall be used. Refer to type NS 35/7.5 according
to standard EN50022.
