Once the brass fitting has been properly installed onto the port, secure the
air hose in place on the fitting by pressing the hose tightly onto the fitting.
4.
Connect the other end of the hose into the fitting on the waveguide flange
or the component to be pressurized with dry air.
5.
Before connecting the power cable, ground the chassis by connecting the
ground lead to the Equipment Ground terminal on the back of the unit.
Refer to Figure 5. The 3-prong power cable provides ground protection,
as well, but this provides additional ground protection for increased safety.

6.
For optional remote communication of the alarm conditions, connect a
DB15 connector to the Alarm Relays port. The three alarm relays are
reverse acting, meaning that the state they take when there is an alarm is
the same state they take when there is no power. Refer to the Alarms
section of this manual for specific pin assignments.
7.
With the ground wire connected, make sure that the power switch is in the
OFF or “O” position, then connect the power cable to the unit and plug it
into a surge protecting electrical outlet power strip. Leave the power
switch in the OFF position.
