This manual contains information explaining how to install and operate single UPS modules and parallel systems
consisting of Vertiv NXC 60kVA UPS.
Read this manual thoroughly before installing, using and servicing the UPS.
Important
This UPS has been designed for commercial and industrial applications in the second environment (see product standard
IEC/EN 62040-2:2006). Installation restrictions or additional measures may be necessary in order to prevent disturbances.
Conformity and standards
This product complies with 2014/35/EU (low voltage safety) and 2014/30/EU (EMC), EMC standards of Australia and New
Zealand (C-Tick), and the following UPS product standards:
* IEC/EN 62040-1+A1:2013 General safety requirements for UPS
* IEC/EN 62040-2:2006-EMC
* IEC/EN 62040-3 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: high earth leakage current
Always connect the unit to earth before connecting the input supply (including both mains and battery supplies).
This equipment is fitted 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 when selecting instantaneous RCCBs (Residual Current Circuit Breaker) or RCDs (Residual Current Device).
Select RCCBs which are sensitive to unidirectional DC pulses (class A) and insensitive to transient state current pulses.
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 codes of practices.
Warning: backfeeding protection
This UPS is fitted with a dry contact closure signal for use with an external automatic disconnecting device (not supplied) used
to protect against backfeeding electrical power into the electrical mains supply via the rectifier or bypass static switch circuit.
A label must be placed on the external bypass input supply disconnectng device warning service personnel that the circuit is
connected to a UPS. The text of the label must read as follows: Risk of voltage backfeed! Isolate the UPS, then check for
hazardous voltages between all terminals including the protective earth before working on this circuit.
