* EKC 202D: DO1 and DO2 are 16 A relays. DO3 and DO4 are 8 A relays. Above
max. load must be kept.
EKC 302D: DO1 is 20 A relay. DO2 and DO3 are 16 A relays. DO4 is a 10 A
relay. 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)
