• 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.
3. Wear rubber gloves and boots.
4. Do not lay tools or metal parts on top of the batteries.
5. Disconnect charging source and loads prior to installing or maintaining the
batteries.
6. Remove battery grounds during installation and maintenance to reduce
likelihood of shock. Remove the connection from ground if any part of the
battery is determined to be grounded. Please note that the battery grounds
mean any battery pole (+/ -) connecting to the ground.
• You must contact Delta customer service if any of the following events occurs:
1. Any liquid is poured or spilled on the UPS.
2. The UPS is deformed.
3. Any conductive powders or metals enter into the UPS.
