Used for instructions that the user must read carefully and observe, even if failure to do so may not result in damage.
This manual contains information concerning the installation and operation of single UPS modules and parallel
systems of the Vertiv EXS 10kVA-20kVA UPS.
Read this manual thoroughly before installing, using and servicing the UPS.
Warning
This UPS has been designed for use in commercial and industrial environments. Installation restrictions or additional measures
may be required to prevent disturbances.
Conformity and standards
This product complies with the Directives 2014/35/EU (low voltage safety) and 2014/30/EU (EMC), and the following UPS
product standards:
* IEC/EN62040-1+A1:2013 General safety requirements for UPS
* IEC/EN62040-2:2006 EMC
* IEC/EN62040-3 Performance requirements and test methods
For more details, refer to Chapter 10 .
Continued compliance requires installation in accordance with these instructions and the use of manufacturer approved
accessories only.
Warning: high earth leakage current
The unit must be connected to earth before it is connected to its AC mains input and battery power supplies.
This equipment is fitted with an EMC filter.
The earth leakage current ranges from 0 to 1000 mA.
Transient and steady state earth leakage currents, which may occur when the equipment is started, should be taken into
account when se4lecting the instantaneous RCCB or RCD devices.
RCCB devices that are sensitive to unidirectional DC pulses (Class A) and immune to transient state current pulses must be
selected.
It is also necessary to take into account that the load earth leakage currents will be borne by the RCCB or RCD.
The equipment must be earthed in compliance with the local electrical code of practice.
Warning
When selecting the UPS system upstream distribution protection devices, ensure that comply with the specifications
indicated in 3.1.4
,
and with the local electrical regulations.
Warning: backfeed protection
This UPS is fitted with a dry contact for use with an external automatic disconnecting device (not supplied) in order to prevent
the UPS voltage from being fed back to the input terminals through the rectifier or bypass static switch circuit. A label must be
placed on or near the all external primary input supply disconnecting devices to warn service personnel that the circuit is
connected to a UPS. The text of the label must have the following meaning: Risk of voltage backfeed! Isolate the UPS, then
check for hazardous voltages between all terminals, including the protective earth, before working on this circuit.
