only be connected to power after correct
wiring or the controller might get
damaged.
CAUTION
- Do not connect the PV
modules to the DC output as it may
damage the PV modules.
AC Input
- Connect AC power to the terminals (L) line
and (N) neutral. Before connecting to grid, check that
the grid connection is properly protected with a fuse
and if required with an ELCB (Earth leakage circuit
breaker). All electrical connections must meet local
and national electrical standards.
Grounding

grounded to meet local and national ectrical
guidelines. The dedicated GND terminal on the AC
input is the grounding connection.
DC power out
- Connect the “DC OUT” of the
PowerPack and the output of the PV generator to the
controller; each via its own PV disconnect. Pay close
attention to the polarity. Install a properly rated DC
disconnect switch between the solar generator and
the pump controller as well.
