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.
The UPS can be connected to IT, TN and TT AC distribution systems (IEC60364-3), and must be of 3-phase 5-wire
(A, B, C, N, PE) system.
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 its 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.
