EU Low Voltage Directive and EMC demands re CE-
marking complied with
Approvals
LVD tested acc. EN 60730-1 and EN 60730-2-9, A1, A2
EMC tested acc. EN61000-6-3 and EN 61000-6-2
* DO1 and DO2 are 16 A relays. The mentioned 8 A can be increased up to 10 A, when the
ambient temperature is kept below 50°C. DO3 and DO4 are 8 A relays. Max. load must be kept.
** Gold plating ensures make function with small contact loads
*** UL-approval based on 30000 couplings.
Capacitive load
The relays cannot be used for the direct connection of capacitive loads such as
LEDs and on/o control of EC motors.
All loads with a switch mode power supply must be connected with a suitable
contactor or similar.
