• The UPS is specifically designed for information technology equipment and used
to power computers, servers, and associated peripheral devices. If you want to
connect any capacitive loads or non-linear loads (that have serious surge current)
to the UPS, it needs to be de-rated according to on-site applications. For such
special applications, please contact Delta service personnel for the accurate UPS
sizing. The UPS is not suitable for connecting with any asymmetrical loads. For the
load suitability, please contact Delta customer service before purchasing.
• 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 object into the
slits and openings that may hinder ventilation.
• Before applying electrical power to the UPS, you must allow the UPS to adjust to
room temperature (20°C ~ 25°C (68°F ~ 77°F)) for at least one hour and ensure
that there is no moisture condensing inside the unit.
• Do not put beverages on the UPS, external battery cabinet(s) or any other
accessory associated with the UPS.
• Do not open or remove the covers or panels of the UPS to avoid high-voltage
electric shock. Only authorized Delta engineers or service personnel can do so for
installation or maintenance. If you want to open or remove the covers or panels, do
it only under the supervision of authorized Delta engineers or service personnel.
• It is not recommended to connect the UPS to any regenerative loads. For the load
suitability, please contact Delta customer service before purchasing.
• The risk of dangerous high voltage is possible when batteries are still connected
to the UPS even though the UPS is disconnected from the power sources. Before
maintenance of the UPS, turn off each external battery cabinet's circuit breaker to
completely cut off the battery power from the UPS.
• Do not dispose of the battery or batteries in a fire. The batteries may explode.
• Do not open or damage the battery or batteries. The released electrolyte is harmful
to the skin and eyes and may be toxic.
• The UPS is electronic equipment that runs 24 hours continuously. To ensure its
normal lifetime, regular maintenance of the UPS and batteries is of vital importance
and necessary.
• Some components like batteries, power capacitors, and fans will become worn-out
due to long-term usage, and this will increase the risk of UPS failure. To replace
and maintain the components, please contact Delta service personnel.
• A battery can present a risk of electrical shock and high short-circuit current.
Contact with any part of a grounded battery can result in electrical shock. The
following precautions should be observed when working on batteries:
1. Remove watches, rings, or other metal objects.
2. Use tools with insulated handles.
