Approvals
EU Low Voltage Directive and EMC demands re CE-
marking complied with
EKC 202: UL approval acc. UL 60730
LVD tested acc. EN 60730-1 and EN 60730-2-9, A1, A2
EMC tested acc. EN 61000-6-3 and EN 61000-6-2
* EKC 202: DO1 and DO2 are 16 A relays. DO3 and DO4 are 8 A relays. Above max. load must be
kept.
EKC 302: DO1 are 20 A relays. DO2 and DO3 are 16 A relays. DO4 are 10 A relays. 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)
Relay contact and controller supply must use same phase and the load (compressor) must phase
compensated to Cos ϕ = 1.
