WARNING
The ambient temperature must not exceed 40 °C (104 °F). Do not operate the UPS near
water or excessive humidity (95% maximum). The system is not intended for outdoor
use.
Before you start any installation or service work, make sure that all AC and DC power
sources are disconnected. Power may come from multiple sources. Also ensure system
grounding / PE continuity.
In a parallel system, the output terminals may be energized even when the UPS is turned
off.
Electric energy hazard. To avoid injury, do not attempt to alter any battery wiring or
connectors.
IMPORTANT: Make sure that you disconnect all battery strings before installation.
CAUTION
Only qualified service personnel knowledgeable of batteries and the required precautions
are allowed to perform installation or service work on batteries. Keep unauthorized
personnel away from the batteries. Before you install or replace batteries, consider all the
warnings, cautions, and notes concerning appropriate handling. Do not disconnect the
batteries when the UPS is in the Battery mode.
Make sure that your replacement batteries are of the same number and type as the
battery that was originally installed in the UPS. See more accurate instructions on the
UPS.
Before you connect or disconnect battery terminals, disconnect the charging source by
opening the corresponding battery circuit breaker.
Check if the battery is inadvertently grounded. If it is, remove the source of the ground.
Contacting any part of a grounded battery can cause a risk of electric shock.
Dispose of batteries according to your local disposal requirements.
Do not dispose of batteries in a fire. When exposed to flame, batteries may explode.
To reduce the risk of a fire, connect only to a circuit that is provided with maximum input
circuit breaker current ratings in accordance with the national and local installation rules.
To ensure proper cooling airflow and to protect personnel from dangerous voltages inside
the unit, keep the UPS door closed and the front panels installed.
Do not install or operate the UPS system close to gas or electric heat sources.
Keep the operating environment within the parameters stated in this document. Keep the
surroundings of the UPS uncluttered, clean, and free from excess moisture.
Observe all DANGER, CAUTION, and WARNING notices affixed to the inside and
outside of the equipment.
