9.2 Mains transformer
The mains transformer supplied is an integral part of the EMC tests. IGEMA only guarantees EMC
compliance when the power supply unit supplied is used.
9.3 Maximum ratings of potential free contacts
Alarm and error output
Switching voltage
max. 250 V AC
Switching current
max. 6 A resistive
inductive: see load profile
Switch outputs
Switching voltage
max. 250 V AC
Switching current
max. 6 A resistive
inductive: see load profile
During switching operations the load profile of the relay is to be observed! Use contactor!
Relay used: Schrack V23092-A1024-A301
If inductive consumers are connected, voltage peaks occur when switching off. For this reason connected inductive consumers (e.g. contactors) must be provided
additionally with an RC circuit: e.g. 0.1µF / 100Ω.
