INSTALLATION
Inspect the controller for any shipping damage.
The MiniVac controller is shipped with the mating
connector for the 24 Vdc supply. This connector must
be wired to the 24 Vdc source, according to the
connections indicated on the MiniVac rear panel
(Pin 1 = positive, Pin 2 = negative).
High voltage developed in the controller can cause
severe injury or death. Before servicing the unit,
disconnect the input power cable.
The MiniVac controller can be used as a bench unit or
as a rack module, but it must be positioned so that free
air can flow through the holes.
