Approvals
EC 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
* Comp and CCH are 16 A relays. Alarm and Fan 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.
