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
