Product Overview

WIRING

For control and power wiring on low voltage actuators (H, G, R, B AND C terminals), use No. 14

wire on runs under 140 feet and No. 12 wire on longer runs. On line voltage units (L1, L2, R, B,

and C terminals), use No. 14 wire on runs up to 1300 feet.

Class I circuits must be used for connections to the control and power terminals (L1, L2, R, B,

and C terminals) on line voltage actuators. Class II circuits may be used for connections to the

control and power terminals (H, G, R, B, and C terminals) on 24 Vac actuators. Connections to

the auxiliary switch terminals (R1, B1, and C1) may be per Class II circuits except when the

switch is used on line voltage applications in which case Class I circuit must be used. When

powering actuators from a common transformer, the G terminals must all connect to the same

side to prevent transformer damage.

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.

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.

Warning:

Failure to observe these warnings 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 below.

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

screws provided.

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.

Refer to Figure-6 for terminal locations.
