Chapter 2 Single UPS Installation And Commissioning

Chapter 2 Single UPS Installation And Commissioning
This chapter introduces the installation, cable connection and commissioning of the single UPS.
Each site has its peculiarity, so this chapter provides the guidance with general installation procedures and methods
for the installation engineer who should conduct the installation according to the actual conditions.
1. The UPS should be installed by an Emerson-authorized engineer according to the information contained in this chapter. If any
problem is found, please get in touch with Emerson local service center immediately.
2. The UPS shall not be powered on without approval of the commissioning engineer.
3. The UPS installation must be carried out by professionals strictly. For other equipment which is not introduced in this manual,
the detailed information about mechanical installation and electrical installation are delivered with the equipment.

2.1 Unpacking Inspection

After the UPS arrival, you should unpack it and check the following items:
1. Visually inspect the UPS appearance for transportation damage. If any problem is found, please notify the carrier
immediately.
2. Check the accessories and models against the delivery list. If any problem is found, please notify the dealer
immediately.

2.2 Installation Preparation

2.2.1 Location

To extend the UPS life, the chosen place must offer:
 Convenient wiring
 Adequate operator access area
 Good ventilation to meet the heat dissipation requirements
 No corrosive gas, like sulfur dioxide
 No excessive moisture or heat source
 No excessive dust
 Compliance with fire-fighting requirements
 Operating temperature compliant with the specifications, see Table 1-2 for details

2.2.2 Environmental Requirements

UPS room
The UPS is designed for indoor installation, which should be installed in a clean and well-ventilated environment, to
keep the environmental temperature within the specifications.
The internal fans provide forced air cooling for the UPS. Cooling air enters the UPS through the ventilation holes on
the rear panel, and exhausts the hot air through the front ventilation holes. Therefore, do not obstruct the ventilation
holes. Maintain at least 200mm clearances between the front, rear, top, bottom, side panels of the UPS and the wall
or adjacent equipment (see Figure 2-1), to avoid obstructing the UPS ventilation and heat dissipation. Otherwise, the
UPS internal temperature will rise, which will shorten the UPS life.
If necessary, an indoor exhaust fan should be installed to keep the indoor temperature from rising. An air filter should
be used in a dusty environment where the UPS is to be operated.
