Elecrical and Pneumatic Connections
All electrical connections must comply with Article 300 - Wiring Methods and Article 500 -
Hazardous (Classified) Locations of the National Electric Code (NEC), and NFPA 70 if installed in the
United States. Reference to the use of this equipment in Hazardous Locations only applies to
installations located within the United States of America. BSGS eV / BULKGUARD eV modules are
designed for use in Explosive Atmosphere Directive (ATEX) locations.
All electrical and pneumatic connections and lines must be installed in accordance with the following
drawings.
“Electrical Details for Typical Installation” located in Appendix A.
“Installation, BSGS eV / BULKGUARD eV Rack” located in Appendix A.
Sealing hubs and low point drains and other means of providing a watertight seal shall be utilized for
outdoor installations. It is also recommended to use poured seals and nitrogen purge for outdoor
applications to minimize effects of moisture on the controller. Additional specifications will have to
be followed for installation within electrically classified areas.
Grounding Method
The equipment must be grounded in accordance with Article 250 - Grounding in the National
Electrical Code, if installed in the United States. The customer is responsible for connections to earth
ground. A ground connection is supplied in the controller for this purpose.
On the plenum of the gas cabinet there is an additional split bolt terminal for connection hookup to the
facilities grounding network. Figure 2.5 shows a suggested grounding method for a typical system.
This drawing may not be applicable to your specific system.
