2.1 UNPACKING AND INSPECTION
Examine the packing carton for damage. Notify the carrier immediately if damage is present. Retain the packing carton for
future use.
2.2 INSTALLATION
The UPS should be installed by professional service personnel. To prevent an overbalance of this equipent, the supporter
must be mounted at the bottom of the enclosure. Please install the supporter to the UPS at the bottom side with six screws (see
Figure 1). Install the supporter at the bottom of the UPS. With the installation of the supporter, tipping of the UPS should be
prevented. The socket-outlet should be near the equipment and easily accessible.
Notes:
● The UPS should be placed in a flat location with a distance of at least 10cm from the wall to the vent. In addition, keep the
UPS away from heat-emitting sources, direct sunshine, rain, or erosive gas.
● Do not place any objects on the top of the UPS.
● The function of an alarm silence is available. Users can silence the alarm by pressing the “ON” button. Press it again will
re-activate the alarm (except when the battery is in low-battery mode.)
● Press the button and hold it for more than 0.5 second to ensure safe operation.
