在规划控制系统安装时，以下几点必须：
考虑过的：
•温度：
–注意环境空气温度以及
附件。较低的温度可提高系统可靠性和
可利用性
–如果超过大允许温度，预计寿命
湿电解电容器和大多数半导体的
减少。
•振动：
–关于常规振动，建议地板：
外壳/机柜位于声音、水平表面和墙壁上
外壳/机柜安装在隔音的垂直墙上。
–AC 800M系统是否应安装在控制室内，邻近
大型机械，如振动筛或大型压力机
如果预计会发生振动，则可使用减震器或隔离垫
需要保护系统设备。减震器通常会：
保护设备免受以下持续低水平振动：
可感知，但不过度。
–建议使用额外的紧固螺钉，以防止
振动是由噪音产生的。
–如果振动或冲击是主要因素，则必须进一步考虑
采取更的措施来减少问题。
•冷却：
–电子设备的冷却通过自对流实现。AC 800M
装置设计用于墙壁安装，必须水平安装
以避免在装置内产生高温。
–ABB机柜（RM550或RE820）可在环境中使用
温度为40°C（104°F），无需额外冷却
设备，如风扇。
第2节安装场地选择和建筑要求
3BSE036351-510 A 61
•接地：
–必须考虑接地、电缆选择和电缆布线
无电磁干扰操作。规划考虑因素包括：
将在后续章节中讨论。
•其他要求：
–独立于设备电源的房间照明。建议使用电池供电的应急照明系统。
–完善的工艺连接，有或无编组
设施
–通过铜排网进行有效接地
–电缆布线遵循标准安装规定。
–电力和其他必要公用设施的可用性。
–遵守标准和法律法规。
–机柜前面有足够的自由空间，以便完全打开
门。出于安全原因，必须始终有足够的可用空间，
即使门处于完全打开位置。

When planning a control system installation, the following points must be
considered:
• Temperature:
– It is important to note the ambient air temperature as well as that within
enclosures. Lower temperatures increase system reliability and
availability.
– If maximum permitted temperatures are exceeded, the anticipated lifetime
of wet, electrolytic capacitors and most semiconductors will be greatly
reduced.
• Vibration:
– Regarding routine vibration it is recommended that floor
enclosures/cabinets stand on a sound, level surface, and that wall
enclosures/cabinets are mounted on sound, vertical walls.
– Should the AC 800M system be installed in a control room, adjacent to
large machinery such as shakers or large presses where frequent major
vibration is expected, then shock absorbers or an isolation pad may be
required to protect system equipment. Shock absorbers will normally
protect the equipment from sustained low-level vibrations that are
perceivable, but not unduly excessive.
– It is recommended that additional fastening screws be used to prevent
vibration-generated noise.
– If vibrations or shock are a major factor, further consideration must be
given to more extreme measures to reduce the problem.
• Cooling:
– Cooling the electronics is achieved by self-convection. The AC 800M
units are designed for wall mounting and must be mounted horizontally
onto a DIN-rail to avoid generating high temperatures within the units.
– ABB cabinets (RM550 or RE820) may be used up to an ambient
temperature of 40°C (104°F), with no requirement for additional cooling
equipment, such as fans.

3BSE036351-510 A 61
• Grounding:
– Grounding, cable selection and cable routing must be considered for
electromagnetic interference-free operation. Planning considerations are
discussed in the subsequent sections.
• Other requirements:
– Room lighting independent of the equipment power source. A batterypowered emergency lighting system is recommended.
– A well-developed process connection, with or without marshalling
facilities.
– Effective grounding through a net of copper bars
– Cable routing observing standard installation regulations.
– Availability of power and other necessary utilities.
– Observation of standards and legal regulations.
– Sufficient free space in front of the cabinet in order to fully open the
doors. For safety reasons there must always be adequate space available,
even with the doors in the fully open position.
For additional information regarding design considerations, see Appendix B, Power
Consumption.
Electro-Magnetic Compatibility
The AC 800M units are intrinsically EMC compatible according to CE marking
rules. For additional information regarding Electro-Magnetic Compatibility,
see Appendix D, Directive Considerations
