Safety Precautions
This manual is about the installation and the operation of UPS (Here after referred as UPS).
Please read this manual carefully before move
、
installation
、
operation and maintenance.
The UPS must be debugged and maintained by professional engineers of manufacturer or qualified
agents. Otherwise, human safety and UPS would be in danger; We do not take the responsibility if the
damage of UPS or human being was caused by users.
UPS is only for commercial / industrial use and not for life long equipment.
APPLICABLE STANDARDS
This product complies with CE 73/23 & 93/68 (low voltage safety) and 89/336 (EMC) , and EMC
standards of Australia and New Zealand (C-Tick) , 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 C3
*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
The earth is critical. Before connect the input supply (include both commonercial power supply and
battery supply) . This equipment must be earthed in accordance to local electrical authority codes of
practice.
Earth leakage current exceeds 3.5 mA and is less than 1000 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 insensitive to DC unidirectional pulses
( class A ) and transient current pulses ( RCCBs) .
Note it that the earth leakage currents of the load will also flow across RCCB or RCD.
Components can be maintained by users
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 contact
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.
Battery Voltage Higher Than 400Vdc
The battery maintenance and service procedures need internal access with special tools and keys
which should be carried out only by trained persons
