Installation Electrical
48 RTHD-SVX01K-EN
Important:
• For factory provided AFD units, verify jumper has
been removed.
• For field installed drives, remove jumper shown in
Figure 21.
AFD Drive Programming
Field replacement drives must be programmed via the
keypad interface. Program non-compressor specific
parameters first in sequential order (Table 16), followed by
compressor specific parameters (see Table 17) in
sequential order.

NOTICE
Equipment Damage!
Changing default clockwise phase rotation or enabling
phase reversal protection could prevent proper chiller
operation or cause equipment damage.
• Do NOT change Adaptive Frequency™ drive (AFD)
phase rotation to counterclockwise.
• Do NOT enable phase reversal protection.
Jumper between
terminals 12 and 37
must be removed
prior to unit
operation.
