  • 4. What is a Modular Enclosure?• A Frame-based design for free-standing cabinets, allowing for additional sections (doors) to be added side to side, front to rear or on top (“baying”, “suiting” or “joining”).• M i t i NEMA integrity (protection rating) Maintains i t it ( t ti ti )• Offers multiple equipment mounting options (depth dj t bl (d th adjustable panel; partial panels; l ti l l chassis bars; 19” racks; door mounting)Panel Savings with New Enclosure Technology 4

  • 8. Benefits of Enclosure FunctionsEnclosuresE l Over and beyond a very basic welded-box, modular enclosures provide:  Much greater range of dimensions in H x W x D  Comprehensive, quick-install accessories  Multiple mounting options within the same platform  Ease of wiring due to removable skins & doors  Unique configurations with standard inventoryPanel Savings with New Enclosure Technology 8
  • 9. Panel SizeMost panel designers only consider p g ythe mounting panel when laying out theirdesign. Thus, enclosure size isdictated by panel size.A Modular, frame-based system canoffer up to 30% more panel space inan equivalent size enclosure vs. awelded box due to the latter’s largeflange support areas (Main panel areas.only- not counting other options).Panel Savings with New Enclosure Technology 9

  • 14. 7. Aesthetics…Aesthetics What kind of impression do you want to make?Panel Savings with New Enclosure Technology 14
  • 15. Common Misperceptions – p p Modular Systems• M d l systems are not as strong (thinner Modular t t t (thi gauge steel) as the traditional style (OGB) – The TS8 holds 3000 lbs., the same as a fully equipped F150 truck• Modular systems are more expensive – They are overall more cost competitive than OGB• Modular systems require a lot of assembly work (“erector set”) – Only the assembly of the side walls is needed to provide a complete enclosure• Must order a bunch of part numbers – Only 2 part numbers are needed to provide a complete enclosure, the same as OGBPanel Savings with New Enclosure Technology 15
  • 16. Technological Improvements• Most designers have switched to current (2000’s) control technology in PLC’s, Starters, Drives, etc.• Yet they package these products in 1940’s-1950’s enclosure designs (end product looks like old technology)• Most are unaware of improvements in enclosure designs unless they study the global market – Most enclosure manufacturers don’t have the technology (esp local fab shops) (esp. – Those that do (other than Rittal) don’t lead with it; they lead with OGB yPanel Savings with New Enclosure Technology 16
  • 17. Technological Improvements• M d l industrial systems offer: Modular i d t i l t ff – Multiple mounting options for components – More flexibility in system designs; lower “Use” costs (thus lower Total cost) – More flexibility in incorporating job changes – Less need for customization (can use pre- ( engineered parts) – Greatly improved aestheticsPanel Savings with New Enclosure Technology 17

True Cost Analysis (Modular Free-Standing vs. OGB)Purchase P iP h Price + U C t = Use Costs True C t T Cost-Enclosure & accessories -Time & Space-oriented tasks: Door removal & replacement, Panel removal & replacement, grounding efforts, ease of access & movement in shop, time on shop floor (throughput), product mounting options, weight/freight factors, ease of cutouts, flexibility y of job changes, range of accessories, ease of installation of accessories, ease of working/wiring inside.Panel Savings with New Enclosure Technology 18
  • 19. Use Cost: Door removal (free standing) (f )• OGB: 30-45 minutes on/off, so most leave door on. Cutouts done on door while enclosure is on its back.• Shavings go in enclosure, require cleaning• C Cannot be working i enclosure at same ti tb ki in l t time• TS8: Door removal 30 sec ; cutouts at bench sec.;• No cleaning in enclosure; can also work in enclosure while door is being cut• No dodging, moving or working around doors.• Similar for Wall Mount doors vs. OGBPanel Savings with New Enclosure Technology 19
  • 20. Use Cost: Panel Insertion (free standing) • OGB: Use crane or fork lift to put enclosure on it’s back, then drop panel in over studs, then raise enclosure back up (Takes up additional space – up. sometimes in aisle). Panel in fixed location. • Approximately 10 min. / enclosure • Usually staged due to limited crane availability • 10 enclosures = 100 minutes total • TS8: 1-2 minutes / enclosure; 10-20 minutes total for 10 enclosures 80/90 min. savings enclosures- • No added space required (for laying down) • Panel depth adjustable in 1” incrementsPanel Savings with New Enclosure Technology 20
  • 21. Use Cost: Grounding (Earthing)• White panel: Drive ground screw; test for ground; if no ground scrape to bare metal; ground, then test again for ground; touch up.• Potentially 4 labor steps per panel• 50 panels / 200 labor steps /100+ minutes possible (vs zinc panels – no added time) (vs.Panel Savings with New Enclosure Technology 21
  • 22. Use Cost: Freight (f standing) (free t di )• OGB 2-door: 300 lbs. (136 kg.) heavier than 2 door: TS8 2-door (Single door to 185 lbs. heavier)• 10 Enclosures = 3000 lbs. (1360 kg.) savings on freight / shipping g gPanel Savings with New Enclosure Technology 22

  • 24. Use Cost: Adding Cutouts• OGB: Cutouts done while enclosure is standing or on its b k it back• Shavings go in box, requires cleaning• Cutouts done wrong must be welded over• Cannot work in enclosure at same time• Cutting 10 or 12 ga. Steel – hard on tools• TS8: Cutting can be done at work bench – no internal cleaning. Errors easily fixed.• Cutting 16 or 14 ga. Steel- easier on tools• Can work in enclosure while cutouts are done on benchPanel Savings with New Enclosure Technology 24
  • 25. Consider this… Cutouts / Modifications When the installer cuts into the panel, will metal filings fall on my electrical equipment? How easy is it to do the cutouts? How do I ensure that the equipment is protected during installation? Do I have enough room inside the enclosure for wire bending (per NEC), wire bundles, termination points, tie-off points and spares? Is there enough room around my enclosure for the installer to work? VsPanel Savings with New Enclosure Technology 25
  • 26. 8. Cable Cutouts / Modifications, cont.andManagementM t How are panel builders and field installers g g to work p going with the enclosure? This impacts how components are installed and how the enclosure is modified, not only inside but outside the enclosure enclosure. Which method saves time and money, is safer and ensures greater quality? or Panel Savings with New Enclosure Technology 26
  • 27. Use Cost: Job Changes (free standing) (f )• OGB: If panel is full and job requires additional equipment installed, a new and larger enclosure is usually required; removal g y q and reinstallation of product follows.• TS8: Optional panels, chassis bars, 19” rack possible for new equipment mounting• Worst case: Add new section (baying) for new equipment. No rework of product.Panel Savings with New Enclosure Technology 27
