System Installation
Install the Fluid Panel (Code E) with Fluid
Meters (Code F)
A non-intrinsically safe fluid panel (Code E–1) is avail-
able for installing in a non-hazardous area. Refer to the
typical installation drawing on page 3–4.
WARNING
FIRE AND EXPLOSION HAZARD
The controller must be configured with
the proper barriers for it to be used with
a fluid panel installed in a hazardous
area. A non-intrinsically safe system
must be installed as shown in Fig. 3.1,
page 3–4.
An intrinsically safe fluid panel (Code E–2) is available
for installing in a hazardous area. Refer to the typical
installation drawing on page 3–5.
NOTE:
The selected fluid meters (S

) are
installed on the fluid panel at the factory.
See page 10–15 for a pneumatic schematic of the
fluid panel.
1. 50 ft. (15.2 m) of cable (C6) is supplied, connect-
ing the fluid panel solenoid box (P) and the Preci-
sionMix II 3K controller (B). See Fig. 3.9.

2. In certain situations, the cable (C6) may need to
be disconnected and reconnected to route the
cable as desired. If this is necessary follow the
steps below and refer to the
Electrical Connec-
tion table and diagram, page 3–29.
Non-intrinsically Safe Fluid Panel Cable Wiring
a. Connect the cable wires to the terminals in the
controller.
b. Connect the cable wires to the terminal blocks
in the solenoid box.
Intrinsically Safe Fluid Panel Cable Wiring
a. Connect the cable wires to the barriers in the
controller.
b. Connect the cable wires to the terminal blocks
in the solenoid box.
c. All wires must be connected to the terminal
blocks and barriers. All shields must be con-
nected to the ground terminal of the appropri-
ate barrier.
3. A cable is factory connected between the solenoid
box and meters to the meters. Bring the free end
of the cables into the solenoid box and connect the
wires to the terminal blocks.
4. Ground the fluid panel to the same true earth
ground used for the controller. See
Grounding
the System on page 3–30.
