Installing the UPS
2.1
Determining the UPS Installation Position
The UPS can be installed on channel steel or the floor. Install the UPS based on site requirements.
Floor installation: Determine the UPS mounting holes using the marking-off template, drill
holes, and install the expansion sleeves of the M12x60 expansion bolts in the mounting holes.
Channel steel installation: Ensure that the distance between the outer surfaces of two pieces of
channel steel is 800 mm and secure the channel steel to the floor using expansion bolts.
Huawei does not provide channel steel or expansion bolts used for securing channel steel. The
customer should purchase channel steel (recommended width: 50 mm or more) and expansion
bolts.
