5 Installation and Connection
(continued)
C232-302-401/402/403/404-603 / C232/EN M/A23 5-9
Connecting the binary
inputs and output relays
The binary inputs and output relays are freely configurable. When configuring these
components it is important to note that the contact rating of the binary I/O modules (X)
varies (see the Chapter on “Technical Data”). Once the user has selected a bay type,
the C232 can automatically configure the binary inputs and outputs with function
assignments for the control of switchgear units. The standard configuration of binary
inputs and output relays for each bay type is given in the list of bay types found in the
Appendix to this operating manual. Terminal assignment is shown in the terminal
connection diagrams found in the Supporting Documents supplied with the unit or in the
Appendix to this manual.
Connection of switchgear
units having direct motor
control
In the case of bay types having direct motor control, one binary input is configured for
the status signal and one output relay is configured for triggering and resetting the motor
relay. Configuration of appropriate output relays for triggering the armature and shunt
windings of motors for switch disconnectors, disconnectors or grounding switches is in
accordance with the ‘List of Bay Types’ (see Appendix). A connection example for direct
motor control is shown in Figure 5-7.
