6 Installation and Setup
This STIIC PLC is set up with basic factory defaults, so the
control requires configuration to match the constraints of
the devices that are installed in the vessel.
6 .1 Making Terminal Connections in
the Electric Box
WARNING: ELECTRICAL SHOCK HAZARD .
Exercise extreme care when working around
energized equipment. Failure to obey this warning
could result in death or serious injury.
The STIIC PLC electric box comes in two different versions,
one with a 24 VDC power supply and one without the
24 VDC power supply. The components inside the electric
box are powered using 24 VDC. Verify which model is
being installed. Figure 6 shows the STIIC PLC electric box
without the 24 VDC power supply.
