Installation kit

The installation kit contains the star jumper on the top and the wiring
jumper on the bottom for connecting the main conducting paths.
1) Use the 3RA19 42-2B base plate for this configuration.
2) Generally possible. If a solid-state time-delay auxiliary switch block is
mounted onto the front of K3, a standard auxiliary switch block can only
be mounted onto the side.
3) Not part of the scope of supply of the preassembled contactor
assemblies; can be ordered as an accessory.
4) See Monitoring and Control Devices: 3RP, 7PV timing relays -> 3RP15
timing relays in 22.5 mm industrial enclosure.
