Usage Warnings
The 2kVA and 3kVA UPSs are class-A products. In a domestic or an office environment, this
product may cause radio interference, in which case, users are required to take adequate
measures.
The UPS can be used to power computers and associated peripheral devices, such as monitors,
modems, cartridge tape drives, external hard drives, etc.
It is not recommended to connect the UPS with the following types of loads. For the load
suitability, please contact Delta customer service before purchasing:
1. regenerative loads (e.g. CNC machines and lifts).
2. asymmetrical loads (e.g. fans with half-bridge drivers and laser printers).
To ensure reliable operation of the UPS and to protect the UPS from overheating, the slits and
openings in the UPS must not be blocked or covered.
Before usage, you must allow the UPS to adjust to room temperature for at least one hour to
avoid moisture condensing inside the UPS.
Do not pour and splash any liquid on the UPS. Do not insert any object into the UPS’s slits and
openings. Do not put beverage containers on or around the UPS.
