Chapter 1 Installing the UPS Module
This chapter explains how to install the Liebert NX 30 - 60kVA UPS (hereinafter referred to as UPS) module, and includes
instructions about unpacking it, carrying out the initial checks, selecting the location, positioning it, and connecting it to external
protective devices and cables.
1.1 Brief Introduction
This paragraph provides a short summary of the factors that must be taken into account when selecting the location and
connecting the UPS and associated devices.
Because each site is different, this chapter does not provide detailed installation steps, and is only intended as a guide to the general
procedures and practices that the installation engineer should implement in order to handle the specific conditions present at the
site correctly.
Note: Handling
The equipment must be kept upright at all times and handled with care; it may be damaged if dropped or subjected to severe impact.
Warning: Professional installation required
1.
The UPS complies with the requirements of EMC Directive 2004/ 108/ EC and the published technical standards.
Continued compliance requires installation in accordance with these instructions and use of approved accessories.
Installation restrictions or additional measures may be needed to prevent radio interference.
2.
Do not apply electrical power to the UPS without the permission of the commissioning engineer.
3.
The UPS should be installed by a qualified engineer in accordance with the information contained in this manual. All equipment not
covered by this manual is supplied with its own specific mechanical and electrical installation instructions.
Note: 3-phase 5-wire input power required
The standard UPS can be connected to 3-phase 5-wire (L1, L2, L3, N, PE) TN, TT, and IT 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 400 Vdc and is potentially lethal.
2. Wear eye protection to prevent injury from accidental electrical arcs.
3. Remove rings, watches, and all metal objects.
4. Only use tools with insulated handles.
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.
