Before you start to connect the power supply cables, note the following drawing with the function
of the terminals:
Afterwards connect the power supply cables accordingly:
• De-energise the power supply cables with the help of a disconnecting device (switch, circuit
breaker)!
• Open the converter housing ( refer to Opening the converter housing on page 22).
• Remove the cover of the power supply terminal (1) by pressing it down and pulling forwards
at the same time (2 and 3), be careful and do not disrupt the retaining band (it prevents the
cover from getting lost)!
• Use a slotted screwdriver with a tip of 3.5 x 0.5 mm / 0.14 x 0.02" to push down the lever,
connect the wires to the terminals and pull up the levers again (4 and 5).
• Refasten the cover of the power supply terminal, close the converter housing and tighten all
screws of the housing.
