Connect Control Outputs
Connect auxiliary equipment, chilled and condenser water pumps, and spare alarms as
required and indicated on job wiring drawings.
Connect Starter
The 19XL is available with either a unit-mounted, factory-installed starter or a free-standing,
field-installed starter (Figure 24 and Figure 25).
Unit Mounted, Factory-Installed Starter
Attach power leads by connecting them from inside the starter cabinet to the line side circuit
breaker terminals. See Figure 24 and Figure 26. Machines with electro-mechanical starters
(wye-delta) will have a top hat shipped with the machine if the RLA is greater than 432 amps.
The top hat is shipped in the knocked-down position and must be assembled and installed on
top of the starter cabinet, over the line side circuit breaker. During assembly, remove the access
plate and use it as the cover piece of the top hat. The top hat provides additional wire bending
space to attach line side power leads to the circuit breaker within the starter. The solid-state
starter does not require a top hat.
