Greenheck MP-100A (463548) - Manual (Page 2)

Motor Pack Quantity
More than one motor pack may be required depending
on damper size. On single panel dampers, the actuator
is installed as shown on page 1 in the Single Panel view.
On double panel dampers, the actuator is installed as
shown on page 1 in the double panel view.
Actuator Specifications
MP-100A motor pack uses a single phase shaded pole
stall type impedance protected electric actuators and
are supplied in various voltages (see chart). For 277,
380, 575 or 600 volt operation, a transformer and a
120V motor pack will be required.
Motor Packs 24V (50/60 Hz)
110 thru 120V
(50/60Hz)
208 thru 240V
(50/60 Hz)
460V (60Hz)
Stall Amps .66 .15 .07 .041
Spec ID# G24 G110-240 G-110-240 G460
Typical Wiring Diagrams
Wiring diagrams are shown for motor packs and dampers installed with power ventilator fan equipment with single speed
motor. The damper will open when the fan is on and close when the fan is off. For connection to 2-speed fan motors or for
other control sequences, consult the factory. The wiring diagrams shown with end switches are for applications where it is
desirable to have the damper fully open before fan start-up.
