Note:
1. The CN5 factory setting is NPN
2. To enable the inverter both inputs, BB and BB1 must be closed. If
only one of the inputs is closed, "BB" will be displayed in the
operator panel and the inverter will not start.

Fig 2.12 Control Circuit Terminal Connections
The base block circuit is a two channel circuit, i.e. always both channels (terminal BB and BB1) have to
be enabled to enable the inverter output.
Generally the terminals BB and BB1 can be linked directly at the terminals. However, if an EN81-1 con-
form one motor contactor solution is required, the recommended BB and BB1 terminal wiring depends on
the installation:
1. If the controller and inverter are mounted in the same cabinet the terminals BB and BB1 can be linked
directly at the inverter terminal board. Only one wire from the controller to the inverter base block
input is necessary.
2. If the inverter is mounted separated from the controller cabinet, two physically separated wires for the
BB and BB1 terminal should be used in order to keep redundancy in case of a fault of one of the signal
lines.
