NOTE: Disregarding this warning may result in malfunction
To avoid malfunction, only snap the connector onto an appropriate terminal. Refer to the
relevant terminal-specific data sheet to select the correct connectors.
Only place black connectors on power or segment terminals.
When the terminal points are jumpered in the black connector, potential is routed through
the jumpering in the connector and not through the printed circuit board of the terminal.
The complete current carrying capacity is ensured through this jumpering.
A black connector must not be placed on a terminal that is to be used for a double signal
connector. Incorrect connection may lead to a short circuit between two signal terminal
points.
