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 is not intended for life support equipment application.
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. This product is not designed for application in an environment:
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
Vertiv disclaims any and all responsibility or liability for the defects 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

Conformity and standards
1. The UPS complies with 2014/35/EU (LVD), 2014/30/EU (EMC), 2011/65/EU (Rohs) and the following product
standards for UPS:
IEC/EN 62040-1, General and safety requirements for UPS
IEC/EN 62040-2: Class C2 compliant
IEC/EN 62040-3: Performance requirements and test methods
2. Continued compliance requires installation in accordance with these instructions and the use of manufacturer
approved accessories only.
Warning
1. Before moving or rewiring the UPS, disconnect mains input power and the battery and make sure that the
UPS is completely shut down. Otherwise, the output terminal may carry live voltage, presenting an electric
shock hazard.
2. Liquid or other irrelevant external objects are prohibited inside the UPS.
3. In case of a fire, a dry chemical fire extinguisher is essential. Using a foam fire extinguisher will cause electric
shock.
4. To prevent the radio frequency of output cables from disturbing other electric equipment, it is recommended
to use the UPS output cable with the length less than 10m.
Warning: high earth leakage current
1. Earth connection is critical before connecting the input supply (including both mains supply and battery).
2. Earth leakage current is less than 2500mA.
3. Transient and steady state earth leakage currents, which may occur when the equipment is started, should be
taken into account 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.
4. Note also that the earth leakage currents of the load will be carried by the RCCBs or RCDs.
5. The equipment must be earthed in accordance with the local electrical code of practice.
Warning: backfeeding protection
This UPS is fitted with a dry contact closure signal for use with an external automatic disconnect device
(supplied independently) to protect against backfeeding voltage into the incoming terminal through the rectifier
or bypass switch circuit. A label must be added at all external incoming primary supply disconnect device to
warn service personnel that the circuit is connected to a UPS. The text of the label has the following m eaning:
Risk of voltage backfeed! Isolate the UPS, then check for hazardous voltage between all terminals including the
protective earth before working on this circuit.

maximum extent
1.2 Design Concept
1.2.1 System Design
This section introduces the working principle of the UPS single module. The UPS adopts AC-DC-AC
converter (as shown in Figure 1-1). The first stage conversion (AC-DC) adopts three-phase high frequency
rectifier to convert the three-phase input voltage into stable DC bus voltage. The second stage conversion
