Important Safety Instruction - Powercom 425A User Manual

WARNING: Manual contains important instructions of UPS and batteries during installation

and maintenance. Follow this instruction at all time.
WARNING: It is recommended to install UPS in an ANSI/NFPA75 room in which temperature

and humidity are controlled and free from electrically conductive particles. DO NOT expose
UPS to direct sunlight or high heat source; DO NOT block off ventilation opening around the
housing.
CAUTION: Before conducting maintenance, repair, or shipment, please turn off everything

completely and disconnect them.
CAUTION: The UPS is NOT applicable for any inductive loads such as motors or domestic

appliances like hairdryers, speakers, and fluorescent lamps.
CAUTION: All interconnection and power cable should be connected ONLY AFTER the UPS

shut down and disconnected from main.
CAUTION: Only use No.26 AWG or larger certified cables to connect UPS and device.

CAUTION: DO NOT unplug UPS from main power during operation or protective ground will

fail. DO NOT disconnect battery under load or shut down may occur.
CAUTION: Ensure the total leakage current of UPS and the connected equipment under

3.5mA.
CAUTION: Ensure UPS connects to grounded main power with a fuse or circuit breaker

protection.
CAUTION: Dangerous amount of voltage might still exist even the UPS disconnects from the

main power since residual voltage exists due to battery supply.
CAUTION: Beware of all the details on the cautionary sticker located on UPS.

CAUTION (No user-serviceable parts): Do not attempt to remove the unit's cover, no

user-serviceable parts inside. Please refer all service to qualified service technicians.

E. Disconnect charging source before connecting/disconnecting battery terminals.
F. Servicing of batteries should be performed or supervised by personnel with necessary
precautions and knowledge. Keep unauthorized personnel away from batteries.
DANGER: Hazardous electric component inside this unit (example: Heat-sinks) remain

energized from the battery supply even when the main power is disconnected.
DANGER: Battery circuit is not isolated from the AC input. Hazardous voltage may exist at

battery terminals and ground—test for safety before any direct contact.
CAUTION: Remove the battery's pole during service inside the battery cabinet or UPS.
