ELECTRICAL INSTALLATION
POWER WIRES INSTALLATION
• The system must be installed and wired only by qualified electricians in accordance with
applicable safety regulations.
• For safety, please cut off the mains power switch before installation.
• When installing the electrical wiring, please note the nominal amperage of your incoming
feeder.
• The UPS must be installed in a location with good ventilation, far away from water,
inflammable gas and corrosive agents.
• Ensure the air vents on the front and rear of the UPS are not blocked. Allow at least 0.5m of
space on each side.
• Condensation to water drops may occur if the UPS is unpacked in a very low temperature
environment. In this case, it is necessary to wait until the UPS is fully dried inside out before
proceeding installation and use. Otherwise there are hazards of electric shock.
(1) It is suggested to install an external isolating device against current backfeed between
mains input and Power module. After the device is installed, it must add a warning label with
the following wording or the equivalent on the external AC contactor:
RISK OF VOLTAGE
BACKFEED
. Isolate the Power module before operating on this circuit, then check for
hazardous voltage between all terminals.
