2. INSTALLATION DIRECTIONS
Wiring must be done while the system is not energized. Remember to
disconnect both the charger/solar- panel and the rechargeable battery.
2.1
CABLE TESTING
Prior to connecting the 2 wired line to the RTUs and to the DREAM they must be checked
as explained in appendix "B".
The following picture shows in details the wiring between the various parts of the system.
In case of multiple 2 wired channels connected to the same Dream, special wiring is
required see appendix "D"
2.2
GROUND CONNECTIONS
Inside the "2W RTU interface", inside the "lightning protection" and in each "RTU" there
are grounding points which have to be well "grounded" otherwise the lightning protection
will not function properly. The resistance to the ground should not exceed 4 ohms.
2.3
SETTING THE ADDRESSES
In order for the DREAM to be able to differentiate between the "2W RTU interface" and
the other I/O interfaces that may exist in the system, each interface must be given a
