lift.
11. Feed the electrical and control connections from
the top tier to bottom tier, and make sure that they

any connections will not be accessible, assemble
the electrical connectors and/or pneumatic tubes
according to the labels before joining the top and
bottom tiers.
12. Lower the top tier onto bottom tier so that mount-
ing brackets mate. Guide the brackets together,
