IMPORTANT SAFETY WARNINGS
Save this manual properly and read carefully the following instructions before installing the unit . Strictly comply with all warnings
and operating instructions in this manual . Do not operate this unit before reading through all safety information and operating
instructions carefully .
Transportation
• Transport the UPS system only in the original package to protect against shock and impact .
Preparation
• Condensation may occur if the UPS system is moved directly from cold to warm environments . The UPS system must be
absolutely dry before being installed . Allow at least two hours for the UPS system to acclimate to the environment .
• Do not install the UPS system near water or in moist environments .
• Do not install the UPS system where it would be exposed to direct sunlight or near a heater .
• Do not block ventilation holes in the UPS housing .
Installation
• Do not connect appliances or devices which would overload the UPS system (e .g . laser printers) to the UPS output receptacles .
• Place cords in such a way that no one can step on or trip over them .
• Do not connect domestic appliances such as hair dryers to UPS output receptacles .
• The UPS can be operated by any individual with no previous experience .
• Connect the UPS system only to a grounded shockproof outlet which must be easily accessible and close to the UPS system .
• When installing the equipment, it should ensure that the sum of the leakage current of the UPS and the connected devices
does not exceed 3 .5mA .
Operation
• Do not disconnect the mains power cord on the UPS system or the building wiring outlet (shockproof socket outlet) during
operation since this would cancel the protective earthing of the UPS system and of all connected loads .
• The UPS system features its own internal current source (batteries) . The UPS output receptacles or output terminals block
may be electrically live even if the UPS system is not connected to the building wiring outlet .
• Prevent fluids or other foreign objects from getting inside the UPS system .
Maintenance, Service, & Faults
• The UPS system operates with hazardous voltages . Repairs may be carried out only by qualified maintenance personnel .
•
Caution
—Risk of electric shock . Even after the unit is disconnected from the mains (building wiring outlet), components
inside the UPS system are still connected to the battery and electrically live and dangerous .
• Before carrying out any kind of service or maintenance, disconnect the batteries and verify that no current is present and no
hazardous voltage exists in the terminals of high capability capacitor such as BUS-capacitors .
• Only people that are adequately familiar with batteries and with the required precautionary measures may replace batteries
and supervise operations . Unauthorized personnel must be kept well away from the batteries .
•
Caution
—Risk of electric shock . The battery circuit is not isolated from the input voltage .
• Hazardous voltages may occur between the battery terminals and the ground . Before touching, verify that no voltage is
present!
• Batteries may cause electric shock and have a high short-circuit current . Take the precautionary measures specified below
and any other measures necessary when working with batteries:
a) Remove wristwatches, rings and other metal objects
b) Use only tools with insulated grips and handles .
c) Wear rubber gloves and boots .
d) Do not lay tools or metal parts on top of batteries .
e) Disconnect charging source and load prior to installing or maintaining the battery .
