following UPS product standards:
• IEC62040-1 General safety requirements for UPS.
• IEC62040-2-EMC
• IEC62040-3 Performance requirements and test methods.
• IEC62040-4 Uninterruptible power supply systems (UPS). Part 4: Environmental factors. Requirements and

For details, refer to Specifications on page171.
Continued compliance requires installation in accordance with these instructions and the use of manufacturer approved
accessories only.
WARNING! High earth leakage current. Earth connection is essential before connecting input power
(including power supply and battery).
• This equipment is installed with an EMC filter.
• Earth leakage current is less than 3000 mA.
• Transient and steady state earth leakage currents, which may occur when the equipment is started, should be
considered 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.
• 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 code of practice.
WARNING! Risk of voltage backfeed. Isolate the UPS, check for hazardous voltage between all terminals
including the protective earth before working on this circuit.
The UPS is fitted with a dry contact closure signal for use with an external automatic disconnect device (supplied by others)
to protect against backfeeding voltage into the incoming terminal through the rectifier or bypass static switch circuit. Place
the warning labels at all external at all external incoming primary supply disconnect device to warn service personnel that the
circuit is connected to a UPS.
