Clutch/Brake Press Controllers

This is a commercial matter, not an Engineering one.

• If the manufacturer installs and commissions the equipment as part of a lump-sum package then any difficulties with the equipment fall entirely within the manufacturer's scope, and there is a price to pay for that.
• If installation and commissioning is by others, then others take on the commercial consequences of that, including any payment issues, and the equipment manufacturer stands back having provided it.

There are a range of possibilities for supply and delivery too: https://en.wikipedia.org/wiki/Incoterms.

And that's why larger organisations have a team of Buyers to make sure these things are nailed down in the contractual arrangements between the parties.

Yes you should always have the supplier install the parts when possible, and have the operator follow recommended safety procedures and be properly trained to operate the machine, these should all be properly documented, and they all work to decrease liability burden....
