Cable entry options: Pass all cables into and out of
the unit through the M25 penetrations that are
provided in the rear of the enclosure. The cable
glands provided in the Parts Kit allow standard
flexible conduit to be connected while maintaining
the IP rating of the enclosure. (Note: penetrations
can be made elsewhere in the enclosure, if more
appropriate) Use the provided cable glands or other
suitable glands to maintain the IP rating of the
system.

Connect the external cables;
o
Decide if the optional wiring for the back-up
feature is required. If it is then in the MSB split
the loads into Essential and Non-essential:
This allows the Back-up feature to be used to
support selected essential loads during a
blackout. A maximum of 3kVA can be supplied
during back-up operation (5kVA during the
day, if PV is connected directly to the SunRise
system), however it is recommended to
connect far lower loads to the essential circuit
as the amount of energy available is limited to
the battery capacity (and the solar
contribution during the daytime) – The Parts
Kit contains a 25A 2-pole MCB to isolate the
Inverter (Grid/Solar) and Essential/EPS
circuits. In addition, a 63A Changeover switch
is included. This is a By-pass switch that
directly connects the Essential loads to the
Non-essential loads. It is only used if the
SunRise system is not operating, or not yet
installed. Labels are also included to use in
the MSB.
o
Connect the AC cables of the Grid and
Essential supplies from the Main Switch
Board (MSB) directly to the terminals inside
the SunRise system (Grid/Solar and
EPS/Essential load supplies). A single 3-Core +
Earth cable of sufficient diamter for the
distance can be used (RedEarth can supply
this cable). Otherwise two 2C+E cables can be
used. In this case the two earths and neutrals
are connected to the Grid/Solar Earth and
Neutral terminals. Note that the essential
circuits are permanently supplied via the
transfer switch inside the SunRise system.
This means that twice the distance from the
MSB to the SunRise needs to used to
determine the cable size for the Essential load circuits.
