As shown in the figure, plug the AC input power cord into the wall socket, then connect your device
into the AC Output socket of the UPS and turn on the AC output switch. The Eishbox 426 is ready to
use. The unit will automatically switch over to power your equipment during a power outage or
loadshedding. Do not connect any device over 400 watts. The unit will shut down and stop working
to protect the batteries. If this happens reduce the load and restart the Eishbox 426.
Indicator
• Power/Fault Indicator: indicates AC power supply status (Normal: Green, Unusual: Red)
• Low Battery indicator display: Red light will flash and the buzzer will ring.
• Overload Indicator: The red light will flash and the buzzer will ring. The unit will no longer provide
power.
• AC Charge Indicator: Indicates AC input charging status (During charging: Red, Fully charged: Green)

The Eishbox 426 will automatically switch over to power your computer in the event of a power
outage. This will provide your computer uninterrupted power during the failover.
• Note:
Do not connect the Eishbox 426 to equipment with a load that is over 400 watts or overload
will occur and the device will shut down. You will need to reduce your total equipment load
and try again. In rare cases, when the unit encounters an external short circuit or unusual
power usage, to protect the Ups and your equipment, the external fuse will blow. You will
need to replace this with an 8A Fuse.

DC POWER SUPPLY
Charging devices via 12V DC Port
Turn on the DC ON/OFF switch. The LED light will turn on and DC 5V and 12V output will be ready
for use. When not using DC power, keep the DC switch off to avoid depleting the battery. When the
battery voltage falls below 9V, the battery is nearly depleted. When this happens please turn off the
DC switch and recharge the UPS
• Note:
Please confirm whether your DC 12V appliance support charging with 5.5mm DC header
interface (the diameter of the DC port of the product is: 5.5mm) otherwise it is unable
to connect with the DC output. You can consult the electrical manufacturer to buy the
corresponding adapter and connect with it. The 12V DC output has a maximum total current
of 6A, each DC output has a maximum current of 3A.
