Chapter 1
This manual contains important instructions that should be followed during installation and maintenance of the
UPS and batteries. Please read all instructions before operating the equipment and save this manual for future
reference. The UPS operates with mains, battery or bypass power. It contains components that carry high
currents and voltages. The properly installed enclosure is earthed and IP20 rated against electrical shock and
foreign objects. However, the UPS is a sophisticated power system and only qualified personnel is allowed to
install and service the UPS.
WARNING
• This UPS contains LETHAL VOLTAGES. All repairs and service should be performed by
AUTHORIZED SERVICE PERSONNEL ONLY. There are NO USER SERVICEABLE PARTS inside the
UPS.
WARNING
• It must be grounded before power-on and operation.
• The output end might carry hazardous voltage even if the UPS is disconnected from AC power
source.
• The terminal block accessible to user may also carry hazardous voltage even if the UPS is shut
down. It's advisable to wait for the full discharge of the capacitor in 5 minutes, and not to approach
the terminal block unless it's tested with a multimeter.
• To avoid fire or electric shock, it's advisable to mount the UPS in an indoor environment with a
controllable temperature and humidity, and ensure that it is free of conductive impurities, and that
the ambient temperature is not higher than 40ºC (94ºF). It's forbidden to operate the UPS near water
or in any humid places (maximum humidity allowed: 95%). This system is not suitable for outdoor
use.
• Connection with loads may also cause large leakage currents, and grounding must be done before
power-on and product operation. When the UPS is running with load, never try to confirm its
operating status via any operation, including disconnecting the earth wire.
• Make sure to disconnect it from all power supplies before installation or maintenance.
• In a parallel system, the output end might carry hazardous voltage even if the UPS is disconnected
from AC power source.
• Batteries may cause electric shock or burning due to large short-circuit current, and the following
precautions shall be taken: 1) Remove any watch, ring, or other metal objects; 2) Use tools with an
insulated handle; 3) Do not place tools or metal parts on top of batteries; 4) Wear a rubber jacket
and a pair of rubber boots.
• Electrical energy is dangerous. Do not attempt to alter any battery wiring or other connecting wiring,
as this may result in injury.
