The max. load listed above must be observed when connecting without zero-
crossing control. When connecting with zero-crossing control, the load must be
increased to the value indicated by 2)
** Gold plating ensures make function with small contact loads
1) With external relay (c70=ON) (zero-crossing control disabled)
2) Without external relay (c70=OFF) (zero-crossing control enabled)
