DANGER
RISK OF BACKFEED VOLTAGE, ISOLATE THE UPS INSTALLING AN EXTERNAL
ISOLATING DEVICE BETWEEN MAINS INPUT AND UPS; BEFORE OPERATING
ON THIS CIRCUIT, CHECK FOR HAZARDOUS VOLTAGE.
DANGER
TO REDUCE THE RISK OF FIRE, THE UNIT SHOULD ONLY CONNECT TO A
CIRCUIT PROVIDED WITH BRANCH CIRCUIT OVERCURRENT PROTECTION FOR:
•
D CURVE 10A RATING (UPSTREAM CIRCUIT), FOR 1kVA (B/S) MODELS,
• D CURVE 16A RATING (UPSTREAM CIRCUIT), FOR 2kVA (B/S) MODELS,
• D CURVE 20A RATING (UPSTREAM CIRCUIT), FOR 3kVA (B/S) MODELS.
DANGER
HIGH LEAKAGE CURRENT:
MAKE SURE THAT THE EARTH WIRE IS CONNECTED.
COMMON INPUT/OUTPUT SOURCES CONNECTION
WARNING
BEFORE CARRING OUT ANY CONNECTION, CHECK THAT THE UPSTREAM
PROTECTION DEVICES (NORMAL AC SOURCE AND BYPASS AC SOURCES) ARE
OPEN “0” (OFF).
WARNING
WATER CONDENSING MAY OCCUR IF THE UPS IS UNPACKED IN A VERY LOW
TEMPERATURE. IN THIS CASE IT IS NECESSARY TO WAIT UNTIL THE UPS IS
FULLY DRIED INSIDE OUT BEFORE PROCEEDING INSTALLATION AND USE TO
AVOID HAZARDS AND ELECTRIC SHOCK, WAIT UNTIL THE UPS IS FULLY DRY
BOTH INSIDE AND OUTSIDE BEFORE INSTALLING.
WARNING
INDUCTIVE LOADS (FOR EXAMPLE MONITORS AND LASER PRINTERS) HAVE A
VERY HIGH POWER CONSUMPTION AT START-UP. IF CONNECTED TO THE
UPS, THE START-UP POWER OF SUCH LOADS MUST BE TAKEN INTO
CONSIDERATION WHEN CALCULATING THE CAPACITY OF THE UPS TO
PREVENT THE UPS FROM BEING OVERLOADED AND TURNED OFF.
NOTE
TO REDUCE THE RISK OF FIRE, CONNECT THE UPS TO A CIRCUIT PROVIDED
WITH BRANCH CIRCUIT OVERCURRENT PROTECTION WITH AN AMPERE
RATING IN ACCORDANCE WITH THE IEC/EN 60934 STANDARD OR YOUR
LOCAL ELECTRICAL CODE.
