nUse one hand, whenever possible, to connect or disconnect signal cables to avoid a possible shock from touching two surfaces with different electrical grounds.
nConnect the equipment to a three wire AC outlet (two poles plus ground). The receptacle must be connected to appropriate branch circuit/mains protection (fuse or circuit breaker). Connection to any other type of receptacle may result in a shock hazard.
nIn order to maintain compliance with the EMC directive, output cords attached to the UPS should not exceed 10 meters in length.
DEENERGIZING SAFETY
nIf the equipment has an internal energy source (battery), the output may be energized when the unit is not connected to an AC power outlet.
nTo deenergize pluggable equipment: first press the OFF button for more than one second to switch the equipment off. Next disconnect the equipment from the AC power outlet, and discon- nect the battery. Finally, push the ON button to deenergize the capacitors.
nTo deenergize permanently wired equipment: set the power switch to standby 
.
nSet the AC circuit breaker to standby 
, then disconnect the battery (including any expansion units). Finally, disconnect the AC power from the building power supply.
nPluggable equipment includes a protective earth conductor that carries the leakage current from the load devices (computer equipment). Total leakage current must not exceed 3.5 mA.
Use of this equipment in life support applications where failure of this equipment can reasonably be expected to cause the failure of the life support equipment or to signifi- cantly affect its safety or effectiveness is not recommended.
BATTERY SAFETY
nThis equipment contains potentially hazardous voltages. Do not attempt to disassemble the unit. The only exception is for equipment containing batteries. Battery replacement using the proce- dures below is permissible. Except for the battery, the unit contains no user serviceable parts.
Repairs are to be performed only by factory trained service personnel.
nDo not dispose of batteries in a fire. The batteries may explode.
nDo not open or mutilate batteries. They contain an electrolyte that is toxic and harmful to the skin and eyes.
nTo avoid personal injury due to energy hazard, remove wristwatches and jewelry such as rings when replacing the batteries. Use tools with insulated handles.
nReplace batteries with the same number and type of batteries as originally installed in the equip- ment.
BATTERY REPLACEMENT AND RECYCLING
See your dealer or the Operation Manual for information on replacement battery kits and battery recycling.
Batteries must be recycled. Deliver the battery to an appropriate recycling facility or ship it to the supplier in the new battery’s packing material. See the new battery instructions for more information.
