Checking for Generator Connection
If a generator is present, the following steps must be carried out:
Checking for Control and Measuring Cables
Check item Check criterion OK Not
applicable
Connection cable The conductor cross-section is sufficient for
the maximum generator current.
The cables are sufficiently protected by
miniature circuit-breakers.
Allocation of the line
conductors for a three-phase
off-grid system
The allocation of the off-grid inverters to the
line conductors of the generator results in a
right-hand rotating magnetic field. Master
must be assigned to L1, slave 1 must be
assigned to L2, slave 2 must be assigned to
L3.
Earthing The generator is earthed.
Check item Check criterion OK Not
applicable
Battery temperature sensor The battery temperature sensor is connected
to the BatTmp terminal.
The battery temperature sensor is attached
at the centre of the battery bank, on the
upper third of the battery cell.
Control and measuring cables
of the Multicluster Box, if
present
The control and measuring cables are
correctly connected (see Multicluster Box
manual).
Measuring cable of the
battery current sensor, if
present
The measuring cable of the battery current
sensor is connected to the BatCur terminal
with the correct polarity
(see Section 6.7"Installing Protective
Devices for DC Sources",page39).
Load shedding activation, if
present
The multi-function relay and the load-
shedding contactors are correctly connected
(see Section 6.22"Connecting the Control
Cables of the Load-Shedding
Contactors",page60).
