1 Important Safety Instructions
Usage Warnings
1. Before usage, unpack the UPS and allow it to adjust to room temperature 68°F to 77°F (20°C to 25°C) for at least two
hours to avoid moisture condensation inside the UPS.
2. The external slits and openings in the UPS are provided for ventilation. To ensure reliable operation of the UPS and to
protect the UPS from overheating, these slits and openings must not be blocked or covered. Do not insert any objects into
the slits and openings that may hinder ventilation.
3. Even though all buttons are in the OFF position, the UPS is not isolated from the mains. To completely isolate the UPS from
the mains, disconnect the input power cord.
4. The unit supplies power from two sources, the mains and the batteries. The output receptacles may have voltage present
even when the unit is unplugged. Unplugging the UPS puts it into Battery Mode and the batteries supply power to the
connected loads.
5. Route all cords well so they cannot be walked on or tripped over.
6. When connecting the unit to the power supply, follow the instructions stated in section 4 Connections.
7. Ensure no objects (e.g. rings, necklaces, paper clips, etc.) get inside the unit.
8. In an emergency, switch off the unit, disconnect it from the mains and contact the responsible customer service
representative.
9. Do not connect any equipment that requires direct current (DC).
10. Do not connect any equipment that may overload the UPS.
11. Do not connect or disconnect any cables during a thunderstorm.
12. The sum of current leakage from the UPS and its connected loads must not exceed 3.5 mA.
13. The UPS has an EPO/ROO (emergency power off / remote on off) port located at the rear. See section 7 Communication
Interfaces for more information.
14. The UPS must be well grounded due to a possible risk of current leakage. The unit is equipped with a safety-inspected
mains line and must be connected to an earth-contact wall socket. If the wall socket does not have an earth connection,
ground the UPS via the ground terminal located at the rear of the UPS. See section 2.6 Rear Panel.
15. Ensure that the sockets on the unit or the earth-contact wall socket are freely accessible.
Battery Precautions
1. Do not open or mutilate the battery or batteries. The released electrolyte is harmful to the skin and eyes and may be toxic.
If the electrolyte splashes into your eyes or onto your skin, flush with water and seek medical advice immediately.
2. Do not dispose of the battery or batteries in a fire. The batteries may explode.
3. The risk of dangerous voltage is possible when the batteries are still connected to the UPS, even though the UPS is
disconnected from the mains. Disconnect the battery cable to completely cut off the battery source.
4. Voltage is always present on the battery terminals.
5. The UPS contains batteries, which are potentially hazardous to the user, even when the UPS is not connected to utility
power.
6. Even when discharged, a battery has the capacity to supply a high short-circuit current, which, in addition to causing
damage to the battery itself and to associated cables, may expose the operator to the risk of burns.
7. To ensure battery performance, idle batteries must be fully recharged every three months if the UPS needs to be stored for
an extended period of time. Whenever you recharge the batteries (internal), fully charge them until the Battery Level Bar
Graph
shown on the UPS's LCD is fully on.
8. Since new batteries often do not provide full capacity after an initial charge, it may be necessary to carry out a number of
discharge/recharge cycles before optimum performance is achieved.
9. Servicing of batteries and battery packs should be performed or supervised by qualified service personnel knowledgeable in
batteries, battery packs and all required precautions.
10. Use only the same type of batteries from the same supplier. Never use old, new and different Ah-rated batteries at the
same time.
