This manual contains important instructions. Please read and follow all instructions
carefully during installation and operation of the unit. Read this manual thoroughly before
attempting to unpack, install, or operate the UPS.
Installation
• This is permanently connected equipment, and it must be installed by qualified maintenance
personnel.
• Condensation may occur if the UPS is moved directly from a cold to a warm environment.
The UPS must be absolutely dry before being installed. Please allow an acclimatization time
of at least two hours.
• Do not install the UPS near water or in damp environment.
• Do not install the UPS where it would be exposed to direct sunlight or near heat.
• Do not connect appliances or items of equipment which would overload the UPS (e.g. laser
printers, etc.) to the UPS output.
• Do not block ventilation openings in the UPS’s housing. Ensure allow at least 0.5m of space
on front and rear of the UPS.
• Connect UPS with the earth reliably before connecting to the building wiring terminal, and
external battery source must also be earthed.
• An integral single emergency switching device which prevents further supply to the load by
the UPS in any mode of operation should be provided in the building wiring installation.
• An appropriate disconnect device as short-circuit backup protection should be provided in
the building wiring installation.
• The equipment is powered by two sources: the mains source, the internal battery or the
external battery source.
• With the installation of the equipment, the sum of the leakage current of the UPS and the
connected load does not exceed 5% of rated value of input current.
Operation
• Do not disconnect the main cable on the UPS or the building wiring terminals during
operation since this would remove the protective earth from the UPS and all connected
loads.
• The UPS output terminal block may still be electrically lived from internal current source
(batteries) even if the UPS is not connected to the building wiring terminal.
• In order to fully disconnect the UPS, turn the input breaker in the "OFF" position first, and
then disconnect the mains lead.
• Indiscriminate operation of switches may cause output loss or damage to equipment. Refer
to instruction before conducting any control.
• While the UPS work as a parallel system, the external parallel cable should be reinforced
insulation.
• Ensure that no liquid or other foreign objects can enter the UPS.
