Before applying electric power to the SVG, you must allow the SVG 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 SVG or any other accessory associated with the SVG.
•
Do not open or remove the covers or panels of the SVG 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.
•
Some components like fans will become worn-out due to long-term usage, and this will
increase the risk of SVG failure. To replace and maintain the components, please
contact Delta service personnel.
•
The SVG complies with the regulations of Overvoltage Category III in IEC 62477. It
is suggested that appropriate surge voltage protection devices shall be chosen in
accordance with the actual power system type. If appropriate protection devices are
not used, the surge voltage may exceed the SVG's capacity and cause SVG
damage. If you are uncertain regarding the SVG's application, please contact Delta
service personnel.
