Before any handling please ensure that the following precautions are taken:
QUALIFIED PERSONNEL Any persons servicing the UPS must be qualified and knowledgeable in UPS
technology and batteries
CLOTHING Correct PPE should always be worn
POWER OFF Ensure all mains power is disconnected before starting work
TOOLS always use insulated tools. Do not lay tools down near the Ups or batteries. Follow all insolation
procedures.
UPS GROUNDING The UPS must always be properly grounded
KEEP THESE INSTRUCTIONS IN A SAFE PLACE
This section contains essential information and instructions that should be followed to ensure the safe handling,
installation and maintenance of CertaUPS equipment and batteries.
AUTHORISED PERSONNEL TO HANDLE ONLY
UPS systems contain both AC and DC when disconnected from the mains outlet and should only be serviced
by qualified persons.

C400R User Manual
Page 7
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 are
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 (Normal AC/Bypass AC) and AC 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 C400R UPS series uses online double conversion technology, which ensures that clean and stable power is always
provided. An online UPS operating in, line mode always provides 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

C400R SERIES STARTUP AND SHUTDOWN
STARTING THE UPS WITH MAIN POWER PRESENT
Please switch off the connected loads before turning on the UPS, and switch on connected devices one by
one after the UPS is turned on. Switch off all connected loads before turning off the UPS.
The C400R Series UPS can be started either “hot” or “Cold”, this means the UPS can be activated regardless
of whether the unit has a main supply (Hot) or if no mains power is available (Cold).
Verify that the total equipment ratings do not exceed the UPS capacity to prevent an overload alarm.
To start the UPS via mains power (Hot start):
1. Check all the connections are properly connected and correct.
2. Supply mains power to the UPS, the fans will start and the LCD will show the default UPS status summary
screen and be in static bypass mode.
3. Hold the button continuously for more than 3 seconds and UPS shall start to turn on.
4. After a few seconds, the UPS will start in Line mode. If the utility power is abnormal, the UPS will transfer to
battery mode without output interruption to the UPS.
5. When the UPS is online the icon will be displayed
STARTING THE UPS FROM BATTERY
Before using this feature, the UPS must have been powered by utility power with output enabled at least
once to ensure the unit is adequately charged.
After connecting the UPS to any EBMs you should wait for at least 10s before pressing the button for pre-
charging of the auxiliary power supply.
Battery start can be disabled.
To start the UPS via battery power (Cold start):
1. Check all the connections are properly connected and correct.
