F. EMI/RFI SUPPRESSION
An EMI/RFI (Radio Frequency Interference)
suppression kit is included with each FoamPro
system. The clamp-on beads included in the kit,
when properly installed, along with proper
grounding of components will reduce the
potential for radio frequency interference.
Additionally, make sure radio cables and
hardware are not located in the immediate area
where the FoamPro 2001 or 2002 equipment is
mounted.
Install clamp-on beads at the locations indicated
in Figure 19. Slide the beads as close as
possible to the connectors on the cable. Use a
small amount GE SILICONE II, electrical tape or
heat shrink tubing to keep the beads from
moving after installation.

E. POWER SUPPLY
Electrical devices can be easily damaged by a
weak or erratic power supply. The FoamPro
2001 and 2002 systems are no different — the
better the power supply, the better the FoamPro
2001 and 2002 will perform and survive (see the
listing on Page 15).
ALWAYS connect the primary positive lead
from the terminal block to the master switch
terminal or the positive battery terminal. Use
8 AWG or larger chemical resistant wire and
protect with a loom.
Connect the ground lead from the chassis frame
or the negative battery terminal to the ground
stud located on the FoamPro 2001 and 2002
foam pump assemblies. Use the same size wire
as the power lead and bore metal connections.
DO NOT connect the main power leads to leads
that are supplying some other device such as a
light bar, siren or primer pumps.
CAUTION: The wires between the terminal
block, diode block and capacitor, as well as the
input power wire, are not protected by the
system circuit breaker. Make sure these wires
are not damaged or short circuited.
