Special Declaration
Personnel Safety
1. This product must be installed and commissioned by professional engineers of the manufacturer or its
authorized agent. Failure to observe this could result in product malfunction or personnel safety risk.
2. Take the time to read this product manual and the safety precaution thoroughly before installing and
commissioning this product. Failure to observe this could result in product malfunction or personnel
safety risk.
3. This product cannot be used as power supply of life support equipment.
4. Never dispose of the internal or external battery of this product in a fire, as it may explode and
jeopardize personnel safety when exposed to flame.
Product Safety
1. If this product will be stored or remain de-energized for a long period, it must be placed in a dry and
clean environment within specified temperature range.
2. This product should be used in an appropriate operating environment. For details, refer to the section
on the environmental requirement in this manual.
3. It is prohibited to use this product in places:
Where the temperature and relative humidity are outside the specifications
Subject to vibrations or shocks
Where conductive dusts, corrosive gases, salts, or flammable gases are present
Near heat sources or strong electromagnetic interferences
Disclaimer
Emerson disclaims any and all responsibility or liability for the defection or malfunction caused by:
Application range or operating environment outside the specifications
Unauthorized modification, improper installation or operation
Force majeure
Other actions not in compliance with the instructions in this manual

Safety Precaution
Always observe the following safety symbols!
Used to alert the user to the risk of death or severe injury should the unit be used improperly.
Used to alert the user to the risk of injury or equipment damage should the unit be used improperly.
Used to advise the user to carefully read and observe this unit though it may not cause damage.
This manual contains important instructions that should be followed during installation and operation of
this Emerson APM 300 integrated UPS system (UPS for short).
Read this manual thoroughly before installing, servicing and using the UPS.
The UPS must be commissioned and serviced by trained engineers approved and qualified by the
manufacturer or its agent. Failure to do so could result in personnel safety risk, equipment malfunction
and invalidation of warranty.
The UPS has been designed for commercial and industrial use only, and is not for use in any life support
application.
Warning
This is a Class C3 UPS product for commercial and industrial application in the second environment. Installation
restrictions or additional measures may be needed to prevent distrubances.
Conformity and standards
The UPS complies with CE 2006/95/EC&93/68/EEC (low voltage safety) and 2004/108/EC, with Australia and New
Zealand EMC Framework (C-Tick), and with the following product standards for UPS:
IEC62040-1 general and safety requirements for UPS
IEC62040-2 EMC, 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.
Multiple power sources
This UPS system receives power from more than one source . Disconnection of all AC sources and the DC source is
required before servicing.
This UPS has several
circuits that are energized with high DC as well as AC voltages. Check for voltage with both AC
and DC voltmeters before working within the UPS.

Warning: high leakage current
Earth connection is essential before connecting the input supply (including the AC mains and battery). The UPS
must be earthed in accordance with local electrical codes.
Earth leakage current exceeds 3.5mA and is less than 3000mA.
Transient and steady state earth leakage currents, which may occur when the equipment is started, should be
taken into account when selecting instantaneous RCCB or RCD devices.
RCCBs must be selected insensitive to DC unidirectional pulses (Class A) and transient current pulses.
Also note that the earth leakage currents of the load will be carried by this RCCB or RCD.
Warning: backfeeding protection
This UPS is fitted with a contact closure signal for use with an external automatic disconnect device (supplied by
others) to protect against backfeeding dangerous voltage into the input terminal through the bypass static switch
circuit. A label must be added at the external power disconnect device to warn service personnel that the circuit is
connected to the UPS. The text of the label has the following meaning: Risk of voltage backfeed! Isolate the UPS,
then check for hazardous voltage between all terminals including the protective earth before working on this
circuit.
User-serviceable parts
All equipment maintenance and servicing procedures involving internal access requires the use of a tool and
should be carried out only by trained professionals. There are no user-serviceable parts behind covers requiring a
tool/special key for removal.
Battery voltage exceeds 400Vdc
All physical battery maintenance and servicing requires the use of a tool or a key and should be carried out only by
trained personnel.
Take special care when working with the batteries. When connected together, the battery terminal voltage will
exceed 400Vdc and is potentially lethal.
Battery manufacturers supply details of the necessary precautions to be observed when working on, or in the
vicinity of, a large bank of battery cells. These precautions should be followed implicitly at all times. Attention
should be paid to the recommendations concerning local environmental conditions and the provision of protective
clothing, first aid and fire-fighting facilities.
Warning
The area around the cover of the monitoring board is a static sensitive area, take anti-static measures when
accessing this area.
Warning
When selecting the UPS system pre-stage distribution protection equipment, ensure that it complies with the
local electric regulations.
The specified upstream breakers are required to obtain the conditional short-circuit current rating, Icc at 10kA
symmetrical rms. The specified upstream breakers should comply with an IEC 60947 series standard.
