Chapter 2 Mechanical Installation
This chapter briefly introduces the mechanical installation of the UPS, including the precautions, preliminary check,
environmental requirement, mechanical requirement and installation diagram.
2.1 Precautions
This chapter briefs the relevant requirements that must be considered in the location selection and cabling of the UPS
and relevant equipment.
Because each site has its particular characteristics, this chapter does not provide 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 apply electrical power to the UPS without permission of the commissioning engineer.
2. The UPS should be installed by a qualified engineer in accordance with the information contained in this manual. All the
equipment not referred to in this manual is shipped with details of its own mechanical and electrical installation information.
Note: 3-phase 4-wire input power required
The UPS must be connected to 3-phase 4-wire (+ PE) AC distribution systems (IEC60364-3).
Warning: battery hazards
1. Take special care when working with the batteries associated with the UPS. When the battery is connected, the battery terminal
voltage exceeds 400Vdc and is potentially lethal.
2. Wear eye protection to prevent injury from accidental electrical arcs.
3. Remove rings, watches and all metal objects.
4. Use tools with insulated handles only.
5. Wear rubber gloves.
6. If a battery leaks electrolyte or is otherwise physically damaged, it must be replaced, stored in a container resistant to sulfuric
acid and disposed of in accordance with local regulations.
7. If electrolyte comes into contact with the skin, the affected area should be washed immediately with water.
2.2 Preliminary Check
Before installing the UPS, carry out the following preliminary checks:
1. Make sure that the environment of the UPS machine room (especially the ambient temperature, ventilation and
dust) meets the environmental specifications of the UPS product.
2. Unpack the UPS, visually examine the UPS and check if there is any external or mechanical damage. If you spot
any damage, seek assistance from the local customer service center of Emerson.
3. Verify the UPS label and confirm the correctness of the UPS. The UPS label is attached on the back of the door.
The UPS model, capacity and main parameters are marked on the label.
2.3 Environmental Requirement
2.3.1 UPS Location Selection
The UPS should be located in a cool, dry, clean-air environment with adequate ventilation. It is suitable for mounting
on concrete or other non-combustible surface only. The ambient environment should be free of conductive powder
