SERIES 90 MODUTROL IV™ MOTORS
Adapter Bracket
The 220738A Adapter Bracket, positioned between the motor and the equipment, raises motor shaft height by 0.75 in.
(19 mm) to match that of the former Modutrol® Motor.
The following applications require this bracket:
•Q607 External Auxiliary Switch.
•Damper linkage applications require added clearance to allow:
•crank arm rotation through the downward position.
•sufficient damper linkage to reach the motor shaft.
•All valve linkages except the Q5001.
NOTE: When no bracket is used in replacement applications, damper linkages require adjustment for the new shaft position.
To mount the motor with the bracket (see Fig. 3):
1.Mount the bracket to the equipment with existing or standard bolts.
2.Using the provided bolts, mount the motor to the bracket threaded holes.
For valve linkage applications (other than the Q5001):
1.Mount the bracket to the linkage.
2.Position the motor on the bracket to align the motor shaft with the linkage.
3.Attach the motor to the bracket with the four bolts provided. See Fig. 4.

Damper Linkages
The motor does not include a crank arm. Order the crank arm, included in the Q605 Linkage, separately (see Accessories in the Specifications section). For detailed instructions on the assembly of specific linkages, refer to the instruction sheet packed with the linkage.
CAUTION
Equipment Damage Hazard.
Stalling a motor can damage the drive shaft. Ensure installation of motors and linkages allows the motor to drive through full stroke without obstruction.
Valve Linkages
The Q100 Linkage requires the 220738A Adapter Bracket for all valve applications. Applications with the Q5001 Valve Linkage do not require the 220738A Adapter Bracket (see Fig. 4).

When used with
Wiring
CAUTION
Electrical Shock or Equipment Damage Hazard. Can shock individuals or short equipment circuitry.
Disconnect power supply before installation.
IMPORTANT
All wiring must agree with applicable codes, ordinances and regulations.
1.Ensure that the voltage and frequency stamped on the motor correspond to the power supply characteristics.
2.When connecting several motors in parallel, ensure that the power supply VA rating is large enough to provide power to all motors used without overloading.
3.Fig. 5 shows that the motor terminals are
4.To access the wiring compartment:
a.Remove the four screws from the junction box top.
b.Lift off the cover.
5.Refer to Fig. 6 for typical wiring, and Fig. 8 for internal auxiliary switch connections.
NOTE: Reverse motor rotation by switching wires at either the motor or the panel. Reverse rotation on the Series 90 models by reversing the wires at terminals W and B.
