CAUTIONARY NOTES
Please be aware of the following risks when handling and operating CertaUPS units.
RISK TYPE
DETAILS
Electric shock
Even after the unit is disconnected from the mains power supply (building outlet
socket), components inside the UPS are still energised from the battery which is
potentially dangerous
The battery circuit is not isolated from the input voltage. Hazardous voltages may
occur between the battery terminals and the ground. Verify that no voltage is present
before servicing.
Hazardous voltages
Repairs must be carried out only by qualified UPS Engineer.
OPERATING SAFETY
Before operating any UPS system, please read the following guidance:
DO NOT install the UPS in a humid environment or expose to liquids
DO NOT block the ventilation of the UPS
DO NOT expose the UPS to direct sunlight or source of heat
DO NOT exceed ambient temperatures when operating or storing the UPS
DO NOT allow excessive particulates or foreign bodies to enter the UPS
DO follow all connection procedures and operational instructions in the order in which they appear within this
manual
DO check that the indicators on the rating plate correspond to the AC powered system and to the actual
electrical consumption of all the equipment to be connected to the UPS
DO ensure the outlet is installed near the UPS and is easily accessible
DO store the UPS in a dry environment
DO keep the UPS in a well-ventilated area
Additional considerations:
•To reduce the risk of fire or injury the unit must be supplied by a circuit which is protected by overcurrent by
means of an MCB or other protective devices.
•The upstream circuit breaker or local means of isolation must be easily accessible. The unit can then be
disconnected from the AC power source by opening the circuit breaker/isolator.
•If An additional AC contactor is to be used for back feed protection, this must comply with IEC/EN 62040-1
•Disconnection and overcurrent protection devices shall be provided by others for permanently connected
AC input and output circuits.
•The admissible storage temperature range is -15ºC to +40ºC with battery, -25ºC to +60ºC without battery.
•The operating temperature should be kept between 20 ºC to 25 ºC, failure to do so will reduce the expected
battery design life

THE TECHNOLOGY
The C400 UPS series uses online double conversion technology, which ensures that clean and stable power is always
provided. An online UPS operating in, line mode will always provide a consistent supply of AC power to the load. This
is done by using the battery and the inverter to ensure a clean stable and supply. When the mains power fails, the
battery is no longer supplied by the rectifier and the batteries begin to discharge.
Once the battery is depleted the UPS will no longer be able to generate AC power through the inverter and the output
will in turn cease. Once the mains power is restored the rectifier will charge the batteries and then allow the inverter
to provide power to the load once more.
Key features:
•Wide input voltage window
•0.9 power factor
•Frequency converter feature
•EPO connection
•Future expansion or redundancy
•Internal manual bypass
•Small footprint

Modes of operation
ECO mode (Economy mode)
Also called high-efficiency mode. After turning the UPS on in ECO mode, the output power will be supplied from
mains power directly via an internal filter while the mains power is within a certain range, so the high-efficiency
performance would be gained in ECO mode. Once the mains power is out of range, the UPS will transfer to battery
mode and the load will be supplied continuously by the battery.
1) ECO Mode can be enabled through the LCD setting or the software (Winpower, etc.).
2) The transfer time of UPS output from ECO mode to battery mode is less than 10ms. It is suggested that this may not
be suitable for applications involving sensitive loads.
CVCF mode
CVCF (Constant Voltage Constant Frequency) also called converter mode. The UPS will work in frequency free-run
with a fixed output frequency (50Hz or 60Hz). Once the mains are lost or abnormal, the UPS will transfer to battery
mode and the load is supplied continuously by the battery.
1) CVCF mode can be enabled through the LCD setting or the software (Winpower, etc.).
2) The normal power rating will be derated to 60% the converter mode.
BY DEFAULT, THE LCD WILL DISPLAY THE UPS STATUS SUMMARY SCREEN.
