Hello, you cannot add additional contacts to that relay.

You can however buy a relay with the same coil voltage and wire it in parallel with the siemens relay.. then use the contacts in this new relay.

I can be more helpful if you tell me what you need the additional contacts for and what the load and voltage specifics are
