3.3 电气连接
考虑到现行规定,连接时至少使用结构型式为
H05 VV-... 电缆。
3.3.1 连接总线和温度传感器 (低电压侧)
连接总线用户时,针对不同的导线横截面需要使
用分配器插座。
通过分配器插座 [A] 对总线用 [B] 进行星形通断
13,第 197 页),或者通过带两个总线接
口的总线用户进行批量通断。
总线连接的最大总长度:
•100 m,导线横截面是 0.50 mm2
•300 m,导线横截面是 1.50 mm2
为了避免产生电感干扰,请将所有低电压电缆与
传导电源电压的电缆分开铺设 (最小距离
100 mm)。
如果存在外部电磁干扰 (例如光伏设备),应该
敷设屏蔽型电缆 (例如 LiYCY)并使屏蔽装置单侧
接地。请勿将屏蔽装置连接在模块中地线的接线
端子上,而应连接房屋接地,例如可用的地线端
子或水管。
延长传感器导线时使用具备下列横截面的传感器
导线:
短于 20 m,导线横截面 0.75 mm2 1.50 mm2
•20m 100 m,导线横截 1.50 mm2
电缆通过预装的锁环走线并按照连接图卡夹。
3.3.2 连接电源、泵和混水阀 (电源电压侧)
请只使用质量相同的电缆。
注意电源的正确相序连接。
不允许通过一个保险插头进行电网连接。
输出端上只能根据本说明书连接部件和组件。
不得连接控制其他设备部件的附加控制系统。
电缆通过锁环走线,按照连接图卡夹并用供货范
围内包含的应力消除装置进行固定 9
12,自 196 页起)
3.3.3 接线端子分布概览
本概览显示哪些设备部件可以连接。带 * 的设备部件
(例如 PS5PS6 PS9)可以进行替换。视模块应用
而定,将其中一个部件连接在接线端子 "VS1PS2
PS3" 上。
视模块应用而定 (在模块上编码,通过控制器进行配
置),应该按照各连接图连接设备部件 à章节 "
接图与设备示例 ")。
构造复杂的太阳能设备可以通过与太阳能模块 MS 200
组合使用来实现。也可以采用其他接线端子分布模式
à安装说明书 MS 200)。
如果超过了所有总线用户之间的总线连
接最大总长度,或者总线系统中存在一
个环形结构,则设备无法调试。
电气连接分配取决于安装的设备。 196
页起,图 9 12 中显示的内容为对电气连
接过程的建议。部分操作步骤未显示为黑
色。这样便于分辨哪些操作步骤属于一类。
所连接部件和组件的最大功耗,不得超过
模块技术参数中规定的功率输出值
如果电源供应没有通过热源的电子元件
进行,施工方应该安装一个符合标准的
全相分离装置 (符合 EN 60335-1 标准)
来中断电源供应。
