Loosen the strain relief screws of the inputs (3, master) and (6, slave 1)
X
and, where applicable, the inputs (7, slave 2) and (8, slave 3) and insert the
cable into the housing and through the strain relief.
Connect the wires in the parallel switch box according to the terminal plan
X
(see Section 3 "Description of connections").
Blue: terminal N
Brown: terminal L
CAUTION
Incorrect connection can cause severe damage to the inverters.
Make sure that all blue cables are connected to N and all brown cables are
X
connected to L.
Retighten the strain relief screws of the inputs (3), (6), (7), (8).
X
Put the grey housing cover in place and fasten with 2 screws.
