WARNING! An electric shock can be fatal. Danger due to grid voltage and DC
voltage from solar modules.
-
Make sure that both the AC side and the DC side of the inverter are de-ener-
gised before making any connections.
-
Only an authorised electrical engineer is permitted to connect this equipment
to the public grid.
CAUTION! Risk of damage to the inverter as the result of incorrectly tightened ca-
ble connections. Incorrectly tightened cable connections can cause heat damage
to the inverter that may result in a fire. When connecting AC and DC cables, en-
sure that all the cables are tightened to the inverter terminals with the specified
torque.
NOTE! Ensure that the phases are connected in the right order: L1, L2, L3, N and
PE.
After connecting the phases, check the rotary field of the grid using a rotary field
measuring device. The inverter is designed for a clockwise rotary field.
