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).
• 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.
NOTE: Refer to Fig. 2 for graphical representation of
fully-open and fully-closed positions.
