Installation with dual connector
a1
During this stage, carefully check that all the terminals are correctly aligned. Any misalignment
of the terminals may result in irreversible damage to the board and/or inverter!
OK
NO
Install the board by fitting the connection terminals of the specific connector
into the inverter board. The inverter board connection, depending on the
model, can have a single connector or two separate connectors (see the
table at the beginning of the chapter).
a2
Tighten the locking screw to secure the board to the inverter. This screw
secures the mounting bracket to a specific anchor point on the inverter
and prevents any unintentional disconnection of the board.
The second hole on the bracket must not be used for securing!
