Connecting power and load
NOTE
The UPS output sockets can be live as soon as the UPS is connected to the main power supply, even if
the UPS has not been switched on via the front panel.
The socket outlet shall be installed near the equipment and shall be easily accessible
NOTE
Grid supply is 208 Volt, 50/60 Hz, fused (see section 3.2)
1.
Add up the power consumption (in VA) of the appliances that will be protected by the UPS (‘the load’) and make sure
that the resulting value does not exceed the VA output rating of the UPS. This way you ensure that the UPS is able to
supply the required output and prevent that an overload situation will happen.
2.
Using the output cords (see note below) connect the load to the appliance outlets (fig. 3.4.3.a) of the unit. Spread the
loads over the appliance outlets as equally as possible. If you use a distribution box to connect more than one
appliance per outlet please take the maximum ratings of the appliance outlets into consideration. See 3.3.
3
Connect the mains cord of the UPS to a working, grounded AC wall socket outlet (fig. 3.4.3.b). The green LED ‘operation’
will blink now: mains power is available and the batteries are charging. If the LED does not blink but illuminates
continuously instead, press keypad ‘0’ for one second.
If both LEDs ‘operation’ and ‘alarm’ blink and the beeper sounds 1/2secs, phase and neutral are reversed at the
input of the UPS. Please read 4.4.13 and take appropriate measures.

For best results, allow the UPS to recharge the batteries during a period of approx. 2 hours. It is acceptable to use
the UPS without first charging the battery, but the runtime may be reduced.
NOTE
To connect UPS and loads use Cables meeting the below requirements:
Detachable UL Listed, SJT Type flexible cord with grounding type plug, maximum 14.76 ft. (4.5m) long.
