Trane RTHD

Installation
SO-SVN048A-EN 53
c. For Compressor Rated Load Amps, enter the value
noted as the Trane Motor Controller nameplate's
Output Current; refer to Figure 89 and Figure 90.
Notes:
• The Compressor Rated Load Amps need to be
increased over the previously set RLA current as this value
now refers to the currents occurring between the drive and
the motor, which are slightly higher (at full load rating point)
than for a Wye Delta Starter Type.
• The new Compressor Rated Load Amps are used to
“calibrate” the UC800 controller so it can provide a current
limit function at the correct current level. Motor protection
becomes a function of the AFD and its settings.
• Current flowing into the unit (into the drive) remains at or
below the previous RLA stamped on the original shipped
RTHD nameplate; thus, there is no need to increase the
upstream branch wiring or circuit protection.
Important: Nameplate values, including Product Model
Number, Product Serial Number, and
Product Sales Order must be set for the unit
as well; refer to Figure 91.
