INSTALLATION

When Installing this Product...
1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous
condition.
2. Check the ratings given in the instructions and on the
product to make sure the product is suitable for your
application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
CAUTION
Electrical Shock or Equipment Damage Hazard.
Can shock individuals or short equipment
circuitry.
Disconnect all power supplies before installation.
Motors with auxiliary switches can have more than
one disconnect.
CAUTION
Equipment Damage Hazard.
Can damage the motor beyond repair.
Never turn the motor shaft by hand or with a wrench.
Forcibly turning the motor shaft damages the gear
train and stroke limit contacts.
IMPORTANT
Always conduct a thorough checkout when
installation is complete.
Location
Allow enough clearance for accessory installation and motor
servicing when selecting a location (see Fig. 1). If located
outdoors, use liquid-tight conduit connectors with the junction
box to provide NEMA 3 weather protection. If mounted
outdoors in a position other than upright, install a 4074ERU
Weatherproofing Kit and liquid-tight connectors to provide
NEMA 3 protection.
CAUTION
Motor Damage Hazard.
Deteriorating vapors and acid fumes can damage
metal parts.
Install motor in areas free of acid fumes and other
deteriorating vapors.
In excessive salt environments, mounting base and screws
should be zinc or cadmium plated, not stainless steel or brass.
Use the 220738A Adapter Bracket for mounting on these
surfaces.
Mounting
Use the following guidelines for proper motor mounting:
• Always install motors with the crankshaft horizontal.
• Mounting flanges extending from motor housing base are
drilled for 1/4 inch (6.4 mm) machine screws or bolts.
• Non-Spring Return Motors are shipped from the factory in
the closed position (at the limit of counterclockwise
rotation, as viewed from the power end of the motor).
SERIES 61 AND SERIES 62 MODUTROL IV™ MOTORS
• Spring Return Motors are shipped from the factory in their
normal position.
• Normally closed models are shipped at the limit of
counterclockwise rotation, as viewed from the power end of
the motor.
• Normally open models are shipped at the limit of clockwise
rotation, as viewed from the power end of the motor.
NOTE: Refer to Fig. 2 for graphical representation of
fully-open and fully-closed positions.

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 previous Modutrol
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 the bracket is not used in a replacement
application, the damper linkage requires adjustment
for the new shaft position.
To mount the motor with the bracket:
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. See Fig. 3.
