SAFETY PRECAUTIONS

This manual contains information concerning the installation and operation of this Emerson Network Power Liebert NX™ Uninterruptible Power System (UPS).

This manual should be read before commencing installation.

The UPS must be commissioned and serviced by an engineer approved by the manufacturer (or agent).

Failure to do so could result in personnel safety risk, equipment malfunction and invalidation of war- ranty.

The Liebert NX has been designed for Commercial/Industrial use only, and is not recommended for use in life support applications.

This is a low emission CLASS A Uninterruptible Power System (UPS) product. In a residential envi- ronment, this product may nevertheless cause radio interference, in which case, the user may be required to take additional measures.

Conformity and Standards

This equipment complies with CE directives 73/23 & 93/68 (LV Safety) and 89/336 (EMC), with Aus- tralia and New Zealand EMC Framework (C-Tick) and with the following product standards for Unin- terruptible Power System (UPS).

•EN / IEC / AS 62040-1-1—General and safety requirements for use in operator access area

•EN / IEC / AS 62040-2—EMC requirements; Class A compliant

•EN / IEC / AS 62040-3—Performance requirements and test methods

For more details, see 9.0 - Technical Specifications

Continued compliance requires installation in accordance with these instructions and the use of man- ufacturer approved accessories only.

! WARNING

High Leakage Current

EARTH CONNECTION IS ESSENTIAL BEFORE CONNECTING THE INPUT SUPPLY. Earth leakage current exceeds 3.5 mA and is less than 860 mA.

Transient and steady-state earth leakage currents, which may occur when starting the equipment, should be taken into account when selecting instantaneous RCCB or RCD devices.

Residual Current Circuit Breakers (RCCBs) must be selected sensitive to DC unidirectional pulses (class A) and insensitive to transient current pulses.

Note also that the earth leakage currents of the load will be carried by this RCCB or RCD. This equipment must be earthed in accordance with the local electrical code of practice.

! WARNING

Back-Feed Protection Notice

This UPS is fitted with a voltage-free contact closure signal for use with an external automatic disconnect device (supplied by others) to protect against back-feeding voltage into the bypass input. If this signal is not used by the installer, a label must be added at the external bypass input disconnect device to warn service personnel that the circuit is connected to a UPS.

The text to use is the following or equivalent:

ISOLATE THE UNINTERRUPTIBLE POWER SYSTEM BEFORE WORKING ON THIS CIRCUIT.
