SAFETY PRECAUTIONS
This manual contains information concerning the installation and operation of 3-phase UPS.
Please read this manual carefully prior to installation.
For safety reasons, this 3-phase UPS must be installed by a certified technician approved by
CyberPower or an authorized representative of CyberPower.
This is a Class C UPS system, and is designed exclusively for commercial or industrial use. It is not
approved for use in a life-support capacity nor in a residential environment.
Symbols Used
The following types of safety instructions and general information appear in this document as
described below:
Symbol Description
hWARNING potentially hazardous situation — please use caution
to prevent serious injury.
iNOTICE please utilize caution to avoid damage to UPS or
power interruption.
INFORMATION critical to ensuring optimal UPS system operation.

SAFETY PRECAUTIONS
h
BACK-FEEDING PROTECTION
This system has a control signal available for use with an
externally located automatic device to protect against
back-feeding voltage through the mains Static Bypass circuit.
If this protection is not used with the switchgear that is used
to isolate the bypass circuit, a label must be added to the
switchgear to advise service personnel that the circuit is
connected to a UPS system.
The text has the following meaning or is equivalent to: Isolate the
UPS before working on the circuit of this UPS.
h
HIGH EARTH LEAKAGE CURRENT
Earth connection is critical before connecting the input supply
(include both utility supply and battery).
“Earth leakage current introduced by the UPS, in any configuration
from 10kW to 150kW, exceeds 3.5 mA and is less than 1000 mA
and complies with the requirements of IEC/EN 62040-1 / UL
60950-1” Transient and steady-state earth leakage currents, which
may occur when starting the equipment, should be taken into
account when selecting instantaneous RCCB or RCD devices.
Residual Current Circuit Breakers (RCCBs) selected must be
sensitive to DC unidirectional pulses (class A) and insensitive to
transient current pulses.
Note also that the earth leakage currents of the load will be
carried by this RCCB or RCD.
This equipment must be earthed in accordance with local
electrical authority codes of practice.
CONFORMITY AND STANDARDS
This product complies with the following UPS product standards:
• UL1778, safety requirements for UPS
• FCC part15, EMI requirements class A
