The changeover contacts (OUT9/OUT10) on terminal X32 are also
intended for connection to the same voltage circuits. The connection of
different voltage circuits is not permitted For voltages above 150 V, it is
necessary that the "COMMON" terminals of OUT9 and OUT10 have the
same voltage potential.

In the field-wiring area, provisions for wiring for Class 2 and Class 3 circuits
shall meet the requirements for separation from Class 1 circuits in
accordance with Section 725 of the National Electrical Code, ANSI/NFPA
70 and Section 16 of the Canadian Electrical Code. Separation from power
and lighting circuits is required for Class 2 by one of the following means:
a) A permanent barrier shall be provided to separate the field installed
Class 2 conductors of secondary circuits from all other circuits or;

Assembly and connection
DANGER
Risk of electric shock!
Before connecting the accessories, switch off the supply voltage of the
controller!
Do not switch on the supply voltage of the controller again until
the installation of the accessories has been completed, the
controller is covered and no live parts can be touched.
ATTENTION
First connect the terminals and then plug them onto the pin header of
the controller! This is the only way to ensure safe contact between the
terminal and the pin header.
NOTE
Use only 75 °C copper cable to connect to the expansion board.
NEC
The description of the connection to the controller can be found
in the assembly instructions of the respective controller.
Required tools: Cross screwdriver PH 1, slotted screwdriver size 0.6 x 3.5
and 0.4 x 2.5
