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 less than 3000 mA.
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 code of practice.
WARNING! The selection of the upstream distribution protection equipment of the UPS shall be selected in
accordance with the details and shall comply with the local electrical regulations.
