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 CE73/23 & 93/68 (low voltage safety) and 89/336 (EMC), and the following UPS product
standards:
*IEC62040-1-1-General and safety requirements for use in operator access area
*IEC/EN62040-2 EMC requirements CLASS C
*IEC62040-3 Performance requirements and test methods
For more details, refer to Chapter 9 . 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 150kW, 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 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 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.
Components that can be maintained by user
All the equipment maintenance and servicing procedures involving internal access need special tools and should be
carried out only by trained personnel. The components that can only be accessed by opening the protective cover
with tools cannot be maintained by user.
This UPS full complies with “IEC62040-1-1-General and safety requirements for use in operator access area UPS”.
Dangerous voltages are present within the battery box. However, the risk of contactor with these high voltages is
minimized for non-service personnel. Since the component with dangerous voltage can only be touched by opening
the protective cover with a tool, the possibility of touching high voltage component is minimized. No risk exists to
any personnel when operating the equipment in the normal manner, following the recommended operating
procedures in this manual.
