Hazardous Voltage.
Can Cause Death, Serious Injury, or Property Damage.
If free and uncovered terminal lugs are touched when the load voltage is switched on,
death or serious injury can result.
For this reason, always cover the free terminal lugs (= free slots that are unassigned for
thermal reasons, for example) with a cover cap. The cover caps are available as
accessories.
Energy is supplied via the infeed terminal 3RM1920-1AA. This means you can connect
conductors with a cross-section of 1.5 mm² to 4 mm².
