n Use one hand, whenever possible, to connect or disconnect signal cables to avoid a possible shock
from touching two surfaces with different electrical grounds.
n Connect 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.
n In order to maintain compliance with the EMC directive, output cords attached to the UPS should
not exceed 10 meters in length.
DEENERGIZING SAFETY
n If the equipment has an internal energy source (battery), the output may be energized when the
unit is not connected to an AC power outlet.
n To 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.
n To deenergize permanently wired equipment: set the power switch to standby .
n Set the AC circuit breaker to standby , then disconnect the battery (including any expansion
units). Finally, disconnect the AC power from the building power supply.
n Pluggable 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
n This 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.
n Do not dispose of batteries in a fire. The batteries may explode.
n Do not open or mutilate batteries. They contain an electrolyte that is toxic and harmful to the skin
and eyes.
n To avoid personal injury due to energy hazard, remove wristwatches and jewelry such as rings
when replacing the batteries. Use tools with insulated handles.
n Replace 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
