Notes:
1. A storage unit contains a base model and any expansion models associated with it.
2. Model 951 attaches to expansion model 95E. The expansion model weighs 123.2 kg (56
lb) fully populated and 2354 kg (5190 lb) combined with model 951.
3.
Weight distribution areas cannot overlap.
4.
Weight distribution areas are calculated for maximum weight of the models.
5.
The base and expansion models of each storage unit are bolted to each other with 5-cm
(2-in.) spacers. Move one side cover and mounting brackets from the base model to the
side of the expansion model. Side clearance for racks that are bolted together applies to
both sides of the assembled racks.
Note: Consult a structural engineer if you are unsure about the correct
placement and weight distribution areas for your units.
Calculating space requirements
When you are planning the installation location, you must first calculate the total
amount of space that is required for the storage units.
Perform the following steps to calculate the amount of space that is required for
your storage units.
1. Determine the dimensions of each model configuration in your storage units.
