This UPS contains LETHAL VOLTAGES. All repairs and maintenance must be performed by AUTHORIZED
There are no USER REPLACEABLE COMPONENTS inside the UPS.
Turn OFF all power before installing and handling power cables.
Reverse polarity connection, short circuit of battery terminals may cause high current, or fire, be sure to connect
the battery correctly.
Cables with sufficient current rating should be used for wiring, secure fixation and proper insulation are all
required to avoid fire accident cause by wired overheat or short-circuit.
Warning
●
This UPS contains its own energy source (batteries) . The UPS output may carry live voltage even when
To reduce the risk of fire or electric shock, install this UPS in a temperature and humidity controlled,
indoor environment, free of conductive contaminants. Ambient temperature must not exceed 40°C
( 104°F). Do not operate near water or excessive humidity (90% maximum).
●
To reduce the risk of fire, connect only to a circuit provided with branch circuit over-current protection .
●
Output over current protection and disconnect switch must be provided by others.
To comply with international standards and wiring regulations, the sum of the leakage current of the
●
UPS and the total equipment connected to the output of this UPS must not have an earth leakage
current greater than 3.5 milliamperes.
If installing optional rack-mount Battery Pack , install the Battery Pack directly below the UPS so that all
●
wiring between the cabinets is installed behind the front covers and is inaccessible to users.
Caution
Batteries can present a risk of electrical shock or burn from high short-circuit current . Observe
