Location Planning When choosing the installation location for your product, make sure that the
location meets the following requirements:
• Allows the product to be installed in a vertical orientation as shown in the
drawings.
• Provides a flat and level mounting surface, allowing the product to make
full contact with the mounting surface and stay stable.
• Allows the bays to be square, and not deformed in any way.
• Provides a mounting surface that can support the weight of the product.
See Approximate Weights on page 31
.
• Does not expose the product to environmental conditions that are
inconsistent with the Environmental Specifications
.
• Provides sufficient space for the product given its dimensions, required
clearances, and access requirements. These topics are covered in the
following sections:
- Approximate Dimensions on page 29
- Overhead Clearance on page 37
- Airflow Clearances and Considerations on page 37
- Service Cart Access Requirements on page 39
Also consider the following when choosing the installation location for your
product:
• Ventilation and air conditioning concerns beyond meeting the ambient
temperature requirements
• Input power cable entry points
• Motor cable exit points
• Alignment with other equipment
• Future needs
