Flexible & Multiple installation options:
The UPS is built with flexible installation in mind, making it suitable for a wide range of setups. It can be placed directly into any standard 19" rack using the included rack ears, or paired with a compatible rail kit if sliding access is preferred. For users who need a freestanding solution, optional vertical brackets allow the unit to operate securely outside the rack. When several external battery modules are arranged in a tower layout, additional stand extensions can be added to keep everything aligned and stable. This adaptable mounting approach helps save space, protects system structure, and keeps maintenance straightforward.
