2. Pre-installation:
previous recommendations
The i500 Series requires basic pre-installation. To avoid future issues and ensure optimal
system operation, follow these recommendations.
2.1. Power Source
Main Speakers (ref. 551 01) and Auxiliary Speakers (ref. 552 01) must be connected to the
mains through wires with PVC isolation according to IEC60227 (H05VV-F 3G 0,75mm
2
) or
alternatively with synthetic rubber according to IEC60245 (H05RR-F 3G 0,75mm
2
).
We recommend that the power source for the Master Unit, Main
Speakers and Auxiliary Speakers and Zone Controllers be from the
same automatic switch in order to facilitate isolation and disconnection
of the sound system independent from the rest of the home’s electrical
consumption. This will also avoid signal reception and sound
interference with other appliances such as extractor fans, air
conditioning, refrigerators, fans and the like (see wiring diagram in
sections 3.1, 4.1 and 4.2).
Installation of Main Active Speakers (ref. 551 01) and Auxiliary Active Speakers (ref. 552 01)
must performed in the way that, once installed, mains connection must not be accesible by
user.
For Master Unit, Zone Controllers and Remote Control Base plug is the disconnection device,
so they must be easily accessible.
IMPORTANT do not supply power to the system until it is correctly installed and
connected.
2.2. Communication Line
The communication line is an 8 wire connecting hose that connects the Master Unit to all Main
Speakers and all Zone Controllers.
To make the connection 4 (yellow) use 1mm
2
cross-section wires. For the remaining
connections use 0.25mm
2
cross-section wires. It may be necessary to increase the wire cross-
section in systems with a large number of units and/or greater distances. In this case, consult
with EISSOUND Technical Service.
Bus-type communication line distribution is necessary to keep the length of the shunts to each
Main Speaker (“stub”) to the minimum. This is especially important in systems greater than 100
meters and/or ten Main Speakers. In smaller systems, star or mixed connections are possible.
2.3. Line Reinforcement module
It may be necessary to use a Line Reinforcement module in some cases. This module would
be plugged into the Main Active Speaker (ref. 551 01).
The location of the device is very important:
