Hazardous Location

Models

Hazardous Location Models

Make all electrical connections to the assembly in accordance with the job wiring diagram,

the National Electric Code Article 500, and in compliance with the local electrical codes.

Two 3/4" pipe tapped openings are provided in the housing for rigid conduit connections. It

is recommended to insert a chase nipple from inside of the housing to prevent threads from

cutting or damaging wiring.

When wiring, take care to lay all leads in the wiring channel located just under the housing

cover to protect the leads from any sharp edges which may be in the vicinity.

The housing and the edge of the cover are stamped with the letter "O." When replacing the

cover, the letters must be aligned with each other.

Warning:

• The cover-to-housing orientation must be maintained in order to preserve the integrity

of the seal. Failure to observe this warning can result in injury or death.

• Do not scrape, scratch, or use abrasives on the machined surfaces.

• Ensure the surfaces are clean.

• Use only the approved compounds listed in the note below.

• If an additional device, such as a drive, is to be installed it must be mounted in the safe

area or enclosed in a separate hazardous location housing.

1. Remove twelve cover screws and cover. Place cover, machined surface up, in a

protected location to avoid damage to machined surfaces.

2. Make all wiring connections to actuator taking care to lay all leads in the wiring channel

provided.

3. Before enclosing the actuator, wipe machined surfaces of housing clean with a lint free

cloth and apply one of the UL approved compounds. See Note below.

4. Secure cover tight against the enclosure in the same position before removal with the

twelve screws provided.

5. Refer to Figure-3 thorough Figure-32 for correct model and application wiring.

Note: Underwriters Laboratories has sanctioned the use of the following compounds on

hazardous location ground joints: Crouse-Hinds type OSL lubricant, Crouse-Hinds type

STL lubricant, or "No-OXID" oil, grade "D."

Two 1/2" conduit knockouts are provided on the actuator case.
