Weight distribution and multiple systems

Edit online

Under typical conditions, service clearances of adjacent products may be overlapped but weight distribution areas should not be overlapped. If weight distribution clearances are overlapped, the customer should obtain the services of a qualified consultant or structural engineer to determine floor loading. Regardless of floor loading, minimum service and aisle clearances must be observed:

  • Rear dimension f is 914 mm (36.0 in).
  • Front dimension e is 1168 mm (46 in).
  • Both f and e are measured from the frame edge (without covers) to the nearest obstacle.
  • Cover opening dimensions are also shown.

Note that aisle clearances are not the same between rows of front-facing and rear-facing covers. Front-facing rows require a minimum of 1168 mm (46 in) of clearance while rear-facing rows need a minimum of 914 mm (36.0 in).

For physical planning purposes, you must verify system placement considering:
  • Weight distribution
  • Power availability
  • Power access
  • Machine and service clearance area
  • Air conditioning delivery
  • Thermal interaction
  • Cable locations
  • Floor tile cutouts.
