4.1.2. Installation Location and Position
The Stack Switchgear is rated to operate in the temperature range of 10 °C to 40 °C. It designed for
indoor applications.
The Stack Switchgear is primarily designed to fit in a standard 19" rack with a 23"-deep cabinet.
However, other mounting possibilities are supported, as the following subsections discuss. Depending
on the desired application, brackets can be ordered with part numbers listed in
Ordering
Information.
4.1.2.1. Mounting Clearances
To maintain safe operating temperatures, it is recommended to leave 1U of space above the unit for
airflow. Depending on the environment, airflow, and ambient temperature, some installations may
require additional clearance above the unit.
4.1.3. Mounting Instructions
For rack and shelf options, the installation can be done by one person. For 2-post options, the
installation requires a minimum of two people.
Fasteners for attaching the brackets to the Stack Switchgear unit (M5 x 8 mm) are included with any
mounting bracket order. If fasteners other than the provided hardware is used, the screws cannot
extend into the Stack Switchgear more than 8 mm. High-voltage and high-power elements that exist
inside the unit could arc to the screw if it intrudes too deep into the unit.
Fasteners for attaching the brackets to the end desired surface are not provided, due to the
application-specific nature. In order to source these fasteners however, note that the corresponding
bracket slots have widths of 6.35 mm.
After removing the Stack Switchgear from its packaging, perform the following steps based on the
mounting brackets purchased.
4.1.3.1. Front-securing Rack-Mount, 19"
Third-party side-support angle brackets are necessary to uphold the weight of the
unit, in this mounting application.
Some examples include RASA22BK3 or RAAB2436BK products by Hammond
Manufacturing (https://www.hammfg.com/).
For front-securing 19" rack installations (i.e. using the NUVP-SSG-RB-19)
1. Install the side-support angle brackets (not included) on the rack at the desired location.
2. Install the brackets on the Stack Switchgear.
3. Place the Stack Switchgear onto the installed side-support angle brackets.
4. Secure the Stack Switchgear to the rail of the rack using the brackets installed.
