Note: The DIN terminals can be used with solid, stranded
or stranded with ferrule termination. The ferrule
will help to prevent 'fraying' of the stranded wires
during installation.
Specific connections are detailed throughout the manual,
refer to the appropriate section prior to making any
connections.
Accessory connections
The accessory terminals are pre-wired to the cable harness
set. The bottom of the DIN rail for accessory connection is
used to for connections to external equipment (ie. Pumps,
etc). The individual terminals are a 'push-in' design,
meaning to install or release a wire, the orange button must
be pushed in (refer to image below for location of orange
buttons denoted by B), prior to installing or removing any
wires to the terminal.
