1.6 Connection to the power supply
i-soamp-2
The
is supplied with an ISO power
adapter as standard equipment.
The power adapter is connected between the
car radio and the vehicle cable harness.
1. Remove the vehicle cable harness ISO power
plug from the car radio and connect it to the
ISO power receptacle of the i-sotec power
adapter.
2. Connect the 2-pole plug at the cable harness
i-soamp-2
of the
to the 2-pole receptacle at
the power adapter. Other vehicle-specifi c
adapters can be connected to the
with this plug-in connection.
3. Connect the ISO power plug of the i-sotec
power adapter to the ISO power receptacle
of the car radio.
Since different vehicle manufacturers switch the
connections at the ISO plug for 12V positive
plus (memory, yellow) and 12V supply voltage
(coupled to the ignition, red), the i-sotec power
adapter has two alternative plug-in connectors
for positive plus:
A. Standard connection for positive plus (as
delivered)
B. Alternative coupling for positive plus
In case of doubt, the correct assignment can be
checked with a voltmeter or test lamp. The 1-pin
coupling (A or B) at which one measures against
ground even with switched off ignition +12V
current, is to be connected to the corresponding
1-pin plug.
