Area 2, option slots Z1 to Z4
The option slots M1 to M8 are designed for M12 plug connectors. No fixed functions are allocated to
the option slots. Primarily, these option slots are used to connect initiators, an integrated option of type
SK CU4-… . However, if required they can also accept plug connectors for connecting other signal
and control cables. The mating plug connector is not included in the scope of supply.
As the built-in plug connector cannot be adjusted during assembly, the use of angled cable plug
connectors is not recommended.
