Connectors
There are two control connectors, the positions of these are shown in the internal
features diagram (page 5). Most uses will only connect to the main 6 way
connector which is accessible without removing the Pro-150's cover.
The auxiliary connector allows some less common controls to be fitted.
The mating connector supplied for both is suitable only for the correct size of wire.
Acceptable wire sizes are:
7 stranded 0.22-0.25mm²
24 AWG (7/32 AWG)
It is an Insulation Displacement Connector (IDC):
Do not
strip the insulation from the wires, simply push them into the top part of the
open connector, from the front (visible in the diagram) and squeeze it closed in a
vice or with suitable parallel action pliers. As you do so, the tines of the contacts
bite through the insulation to make contact with the conductors.
Wire which is too thick will damage the tines which may short to each other. Solid
wire may fatigue and break with use.
You can re-open a closed connector by gently moving the tabs at the sides of the
top cover outward to disengage the latches while lifting the cover slightly, one side
at a time. Wire which is too thin will not make good contact.
