Approvals
EU Low Voltage Directive and EMC demands re CE-
marking complied with
LVD tested acc. EN 60730-1 and EN 60730-2-9, A1, A2
EMC tested acc. EN 61000-6-2 and EN 61000-6-3
Relays are tested acc. to IEC 60079-15
* DO3 and DO4 are 16 A relays. DO2, DO5 and DO6 are 8 A relays. Max. load must be observed.
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 simi-
lar.
