Always use suitable wiring techniques and crimps when terminating cable cores, especially if
running two cores to a single terminal.
Signal and DC power connections are made via a
16-wire
terminal block. Mains power is
connected via a separate
3-wire
terminal block.
The diagram shows the
16-wire
terminal block layout with terminal identifiers.
This table lists the terminals and their functions and specifications.
