电气连接

使用符合

EN 60 335-1

标准的电缆。

所有连接到燃烧器接线端子板上的电缆都必须穿入随附的
导缆孔。
导缆孔及备用孔可有多种用途，如：

1 -

三相电源

2 -

单相电源

3 -

触发

安全装置

4 -

备用

工厂中所使用的电缆护套：

A -

风机电机

B -

伺服电机

C -

油泵电机

D -

安全电磁阀

E - 1

段火电磁阀

F - 2

段火电磁阀

注意

RL 250 MZ

型燃烧器为间歇式运行即至少每 24 小时强制停机一次以便对控制盒进行自检，确保其功能的有效性。正常情况下，锅炉负荷控制系统

会自动将燃烧器停机。
如果不是这种情况，则需在燃烧器中串联一个定时器以保证燃烧器至少每 24 小时停机一次。

电气连接必须由具有资质的技术人员操作，且必须符合安装地的强制标准。
因改变本手册电气连接图或电气连接与图不符而造成的后果，利雅路公司将不承担任何责任。

警告

在电气连接中勿将零线与火线接反。
