Ordering Information for Stations

Stations

Bulletin 800H Type 7 & 9 stations are available as factory assembled or as components for field assembly.

Factory-Assembled Stations

Bulletin 800H Type 7 & 9 control stations are designed to meet the requirements of the National Electrical Code. These stations are listed by Underwriters Laboratories, Inc. for Class I, Divisions 1 & 2, Groups C & D Hazardous Gases or Vapors, Class II, Divisions 1 & 2, Groups E, F & G Hazardous Dust and Class III Hazardous Fiber Locations. In addition the single gang shallow base, Cat. No. 800H‑IHZX7, meets Class I, Group B requirements as defined in the National Electrical Code.

Factory-assembled stations may be ordered in three ways:

• Standard, factory-assembled stations listed on Complete Assembled Stations (Supplied with 3/4 in. Dead End Conduit Entry — Cat. No. 800H‑1HZX7).
  
• Custom, factory-assembled stations can be ordered by following the instructions listed on this page.
  

Components for Field Assembled Stations

Eight-gang maximum⋆ . These 2- and 3-gang modules may be assembled into the multi-gang stations by installing a coupler kit between the enclosures. These separate bases, covers, or bases with covers are Underwriters Laboratories, Inc. listed when properly assembled. These enclosures meet the requirements of Class I, Division 1 & 2, Groups C & D, Class II, Divisions 1 & 2, Groups E, F & G, and Class III hazardous locations as defined in the National Electrical Code. Bulletin 800H Type 7 & 9 components are designed for these modular enclosures and are UL Listed for this purpose.

Note: Components may be assembled as multi-gang units up to an eight-gang maximum⋆ .

To select components for field assembly, follow the instructions for ordering a custom-built station.

Instructions for Ordering Custom-Built Stations

1.  Select operators required from Complete Assembled Stations (Supplied with 3/4 in. Dead End Conduit Entry — Cat. No. 800H‑1HZX7). (If lever type, select covers from Covers, Lever Type Actuator and go to Step 3).

2.  Select covers based on mounting requirements on Covers, Lever Type Actuator.

3.  Select an assembled base from Assembled Bases (for Field Assembly and Custom Stations) in accordance with the number of covers selected in Step 2.

4.  Select legend plates from Legend Plates…Legend Plates, Continued (and accessories, if required, from pages Modifications and Accessories…Locking Attachments).

5.  If a particular sequence of operators or mounting orientation (vertical versus horizontal) is required, include a rough sketch.

Station Design Guidelines

(Also see Applicable Codes and Standards)

1.  Push-to-test pilot lights, illuminated push buttons, push-to-pull units, 4-position selector switches, and all operators with two contact blocks fastened along side one another or with a power module and contact block along side one another must be installed in a single hole cover.

2.  Dual push button units may only be installed in a single-hole cover or the specially designed two-hole cover (Cat. No. 800H-NP33), which can accommodate the dual push button and the special pigtail pilot light (Cat. No. 800H-LPK10R).

3.  When two components are installed in one cover, contact blocks are restricted to one side of the operator. Contact blocks of each operator must face each other.

4.  One level of contact blocks is maximum in a shallow base or deep base when used with a sealing well. Contact blocks, except sealed switch type, may be mounted two deep in other bases.

5.  If sealed switch contact blocks or a sealing well are used, a deep enclosure is required.

6.  a. START push buttons should be green or black flush, installed to the left or above STOP push buttons.
b. EMERGENCY STOP push buttons should be a red mushroom.
c. STOP push buttons should be red extended, installed to the right or below START push button.
d. STOP push buttons should be installed in the last position (bottom or right) of each unit when required.
e. Pilot lights should be installed in the first position (top or left side) of each unit when required.



Design Guideline #1

Push-to-test pilot lights, illuminated push buttons, push-pull units, 4-position selector switches, all operators with two contact blocks fastened along side one another or with a power module and contact block along side one another must be installed in a single hole cover.



Design Guideline #2

Dual push button units may only be installed in a single hole cover or the specially designed two hole cover (Cat. No. 800H‑NP33), which can accommodate the dual push button and the special pigtail pilot light (Cat. No. 800H‑LPK10R).



Design Guideline #3

When two components are installed in one cover, contact blocks are restricted to one side of the operator. Contact blocks of each operator must face each other.

Design Guideline #4

One level of contact blocks is maximum in a shallow base or deep base when used with a sealing well. Contact blocks, except sealed switch type, may be mounted two deep in other bases.

⋆ Flange width is designed to comply with Underwriters Laboratories standards to enclosures with an internal free volume of up to 300 cubic inches (a maximum 8-gang assembly).
