Local module power
In the majority of installations, the local module will derive all of its power
successfully from the USB link with the computer system. However, if insufficient
voltage is available from the computer system, the green indicator
adjacent to the link connector will flash. If this occurs (or if you do
not intend to use the USB connection with the computer) you will
need to purchase and use a power supply identical to the one used
for the remote module (part number: PSU-IEC-5VDC-2.5A) from
your Adder stockist.

1 If external power input is
necessary, attach the output
connector of the optional power
supply to the ‘POWER’ socket of
the local module.
2 Attach the IEC power lead
to the power supply body
and insert the mains plug
of the lead to a nearby
power outlet.
Note: If a power adapter is
plugged into the module
but not switched on, it
will prevent the unit from
deriving power from the
USB connection.
