Accessing the electrical terminal block and fuse
Remove the front panel ( *** 'Opening the front panel' on page 189 ***) to access the terminal block (M) and fuse (F) by
proceeding as follows (fig. 20 and fig. 21). The terminals indicated in fig. 21 must be with voltage-free contacts
(not 230V). The arrangement of the terminals for the various connections is also given in the wiring diagram in fig. 58.
Variable output relay LC32 card (optional - 043011X0)
