SERIES 90 MODUTROL IV™ MOTORS
63-2631 6
Fig. 3. Mounting the motor with an adapter bracket.
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).
Junction Box
When used with liquid-tight conduit connectors, the junction
box provides NEMA 3 weather protection for the motor. The
junction box, standard with replacement motors, encloses the
terminals and provides knockouts for wiring conduits. Housing
an internal transformer or internal auxiliary switches requires
use of the junction box.
