3.3.5 Connecting interface devices
If you do not want to use the communication capabilities of the UPS, please skip this section and
proceed with 3.3.6.
The UPS is equipped with two interface ports: a USB port and an RJ 11 port, allowing advanced
communication between the UPS and a computer (network). Refer to chapter 5 for more detailed
information.
3.3.6 Connecting power and load
1
Switch off your computer, and unplug it
from the socket-outlet.
2
VH Series 700-2000:
Disconnect the power cord from the
computer (rating 250Vac/10A) and
connect this cord to the male input
socket (1, fig. 3.3.3a/b) at the rear of
the UPS.
VH Series 3000 only:
Connect the cord that came with the
UPS to the male input socket.
3
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.
4.
Using the output cords provided,
connect the load to the appliance
outlets (3/3a, fig. 3.3.3a/b) 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 note
that the maximum AC-current rating of
each appliance outlet is 10A (outlet 3)
or 16A (outlet 3a). See fig. 3.3.3a/b.
5
Connect the mains cord of the UPS to a
working, grounded AC wall socket
outlet. 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 4.4.12 and
take appropriate measures.
