For 3 phase, damper motor voltage should be
the same between L1 and L2. For single phase
application, disregard L3. *Damper motors may be
available in 115, 230 and 460 volt models. The damper
motor nameplate voltage should be verified prior to
connection. **A transformer may be provided in some
installations to correct the damper motor voltage to the
specified voltage.
