personnel safety is at risk.
1.1 Product Safety
1. If this product is stored or remain de-energized for a long period, it must be placed in a dry and clean
environment within specified temperature range.
2. The environmental requirements must be fulfilled while operating the UPS. See Environmental Requirement on
page26.
3. The UPS is designed for application in the following conditions:
•Where the temperature and relative humidity are not in specified range given in the Specifications on
page171.
•Is not subjected to vibrations or shocks.
•Where conductive dusts, corrosive gases, salts, or flammable gases are not present.
•Away from heat sources or strong electromagnetic interferences.
WARNING! The UPS with standard configuration is a product for commercial and industrial application in the
atmospheric environment (with dust, corrosion, electromagnetic interference). Installation restrictions or
additional measures may be needed to prevent disturbances.

1.3 Safety Precautions
Always observe the following safety symbols.
WARNING! Used to alert the user to the risk of death or severe injury should the unit be used improperly.
NOTE: Used to alert the user to the risk of injury or equipment damage should the unit be used improperly.
IMPORTANT! Used to advise the user to carefully read and observe this unit though it may not cause damage.
Conformity and standards
This device complies with CE 2014/35/EU (Low Voltage Safety), 2014/30/EU (EMC) and 2011/65/EU (Rohs), as well as the
following UPS product standards:
•IEC62040-1 General safety requirements for UPS.
•IEC62040-2-EMC
•IEC62040-3 Performance requirements and test methods.
•IEC62040-4 Uninterruptible power supply systems (UPS). Part 4: Environmental factors. Requirements and
reports.
For details, refer to Specifications on page171.
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 essential before connecting input power
(including power supply and battery).
•This equipment is installed with an EMC filter.
•Earth leakage current is less than 3000 mA.
•Transient and steady state earth leakage currents, which may occur when the equipment is started, should be
considered in the selection of instantaneous RCCBs or RCD devices.
•RCCB which is sensitive to unidirectional DC pulse (class A) and insensitive to transient state current pulse must
be selected.
•The earth leakage currents of the load will be carried by the RCCBs or RCDs.
•The equipment must be earthed in accordance with the local electrical code of practice.
WARNING! Risk of voltage backfeed. Isolate the UPS, check for hazardous voltage between all terminals
including the protective earth before working on this circuit.
The UPS is fitted with a dry contact closure signal for use with an external automatic disconnect device (supplied by others)
to protect against backfeeding voltage into the incoming terminal through the rectifier or bypass static switch circuit. Place
the warning labels at all external at all external incoming primary supply disconnect device to warn service personnel that the
circuit is connected to a UPS.
