Chapter 2 Mechanical Installation
This chapter briefly introduces the mechanical installation of the UPS, including the precautions, initial inspection
before installation, environmental requirement, mechanical requirement and installation diagram.
2.1 Precautions
This chapter describes the environmental and mechanical requirements and mechanical considerations that must be
taken into account when planning the positioning and cabling of the UPS equipment.
Because each site has its particular characteristics, this chapter does not provide the detailed installation steps, it only
acts as a guide for the general procedures and practices that should be observed by the installing engineer, so that
they can properly handle the specific situation of the site.
Warning: professional installation required
1. Do not disassemble the package without permission of authorized service engineer.
2. The UPS should be installed by an authorized engineer in accordance with the information contained in this chapter.
Warning: battery danger
Take special care when installing batteries. When connecting batteries, the battery terminal voltage will reach 320Vdc, which is
fatal to human being.
1. Please wear safety glasses to protect the eyes from being damaged by arc.
2. Remove all the metal items, including finger rings, watch, etc.
3. Use tools with insulated handle.
4. Wear rubber gloves.
5. If the battery has electrolyte leakage or the battery is damaged, it must be replaced. Place the battery into the container that can
withstand sulfuric acid and dispose of it according to the local regulations.
6. If the skin contacts the electrolyte, flush it with water immediately.
2.2 Transportation
Railroad transportation and shipping are the recommended means of transportation. If truck transportation is
unavoidable, choose roads that are less bumpy in order to protect the equipment.
The UPS cabinet is heavy (see Table 11-3 for the weight). It is recommended to use mechanical equipment such as an
electric forklift to unload and move the equipment to the place closest to the installation site. If an electric forklift is
used, insert the tines of the forklift below the bottom pallet (as shown in Figure 2-1) to prevent the equipment from
falling over.

2.3 Unpacking
Unpack the UPS and battery packages under the guidance of authorized service engineer. Steps:
1. Remove the side panels and top cover.
