Safety Precautions
This manual contains information concerning the installation and operation of Modular UPS. Please carefully read this
manual prior to installation.
The Modular UPS cannot be put into operation until it is commissioned by engineers approved by the manufacturer (or its
agent). Not doing so could result in personnel safety risk, equipment malfunction and invalidation of warranty.
The UPS has been designed for commercial or industrial use only, and is not intended for use in any life support application.
This is a CLASS C Uninterruptible Power Supply (UPS) product. In a domestic environment, this product may cause radio
interference, in which case, the user may be required to take additional measures.
Conformity and standards
This product complies with 2006/95/EC ,CE73/23 & 93/68 (low voltage safety) and 2004/108/EC, 89/336 (EMC), and the
following UPS product standards:
*IEC62040-1 General and safety requirements for use in operator access area
*IEC/EN62040-2 EMC requirements CLASS C
*IEC62040-3 Performance requirements and test methods
Continued compliance requires installation in accordance with these instructions and the use of manufacturer approved accessories
only.
WARNING: high earth leakage current
Earth connection is critical before connecting the input supply (include both utility supply and battery).
"Earth leakage current introduced by the UPS, in any configuration from 10kW to 200kW, exceeds 3.5 mA and is less than 1000
mA and complies with the requirements of IEC/EN 62040-1 / IEC/EN 60950-1" 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 (class B) and insensitive to transient current pulses
Type S.
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 local electrical authority codes of practice.
WARNING: backfeeding protection
This system has a control signal available for use with an automatic device, externally located, to protect against backfeeding
voltage through the mains Static Bypass circuit. If this protection is not used with the switchgear that is used to isolate the bypass
circuit, a label must be added to the switchgear to advise service personnel that the circuit is connected to a UPS system.
The text has the following meaning or is equivalent to: Isolate the UPS before working on the circuit of this UPS.
