parallel system of the Vertiv NXC 60kVA UPS.
Read this manual thoroughly before installing, using and servicing the UPS.
Note
Notes to the CE Declaration of Conformity
The UPS conforms to the following European directives:
2014/35/EU - Directive of the council for adapting the legal regulations of member states on electrical
equipment for use within specific voltage limits (superseding the 2006/95/EC and successive amendments).
2014/30/EU -
Directive of the council for adapting the legal regulations of member states on electromagnetic
compatibility, (superseding the 2004/108/EC and successive amendments).
Conformity is established through compliance with the following standards:
*IEC/EN 62040-1+A1:2013
*IEC/EN 62040-2:2006
Additional information regarding adherence to these directives is included in the appendices NSR and EMC to
the Declaration of Conformity. If needed, the Declaration of Conformity can be requested to Vertiv.
Warning
System without C2 EMI filter: This UPS is a product for commercial and industrial application in the second
environment. Installation restrictions or additional measures may be required to prevent disturbances.
Warning
System with C2 EMI filter: This UPS is a category C2 UPS product. In a residential environment, this product
may cause radio interference, in which case the user may be required to take additional measures.
Conformity and standards
This product complies with CE 2006/95/EC (low voltage safety) and 2004/108/EC (EMC), EMC standards of
Australia and New Zealand (C-Tick), and the following UPS product standards:

* IEC62040-1 General safety requirements for UPS
*IEC62040-2-EMC
* IEC62040-3 Performance requirements and test methods
For details, refer to Chapter 11 Specifications.
Continued compliance requires installation in accordance with these instructions and the use of manufacturer
approved accessories only.
Warning
The selection of the upstream distribution protection equipment of the UPS shall be selected in accordance
with the details in 3.1.4 Selection Of UPS I/O Switch and shall comply with the local electrical regulations.
Warning: high earth leakage current
Earth connection is critical before connecting the input supply (including both mains supply and battery).
This equipment is installed with an EMC filter.
Earth leakage current is 0 ~ 1000mA.
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.
Note also that 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 authority code of practice.
General safety precautions (For users)
Like other types of large power equipment, the UPS and battery circuit breaker box/battery cabinet have high
voltage inside. Because the components with high voltage can be accessed only when the front door (which is
locked) is opened, the risk of contacting high voltage has been minimized. This equipment meets the IP20
standard, and other safety shields are provided inside the equipment.
There will not be any danger when operating this equipment according to the general instructions and the
steps recommended in this manual.
Multiple power inputs (For users)
This UPS system receives power from more than one source. Disconnection of all AC source and the DC
source is required before servicing.
This UPS has several circuits that are energized with high AC as well as DC voltages. Check for voltage with
both AC and DC voltmeters before working within the UPS.
User serviceable components (For service personnel)
All equipment maintenance and servicing procedures involving internal access requires the use of a tool and
should be carried out only by trained personnel. There are no user-
serviceable parts behind covers requiring a
tool/key for removal.
Battery voltage: 300Vdc ~ 564Vdc (For service personnel)

All physical battery maintenance and servicing procedures requires the use of a tool and should be carried out
only by trained personnel.
Take special care when working with the batteries associated with this UPS. When connected together, the
battery terminal voltage will exceed 300Vdc and is potentially lethal.
Battery manufacturers supply details of the necessary precautions to be observed in working on, or in the
vicinity of, a large bank of battery cells. These precautions should be followed implicitly at all times. Particular
attention should be paid to the recommendations concer
ning local environmental conditions and the provision
of protective clothing, first aid and fire-fighting facilities.
Warning
When the internal fuse of the UPS is damaged, it must be replaced with fuse of the same electric parameters
by qualified personnel.
Important
Beside the communication board is a static sensitive area, ESD-proof action is critical before contacting with
this area.
