ELECTRICAL CONNECTIONS
Complete harness electrical diagrams are provided
(
Figure 45 a n d Figure 46 ) . Refer to these diagrams
for proper installation of each of the electrical compo-
nents.
The Hale SmartFOAM system is designed to be installed
with a minimum of electrical connections. Cables are
provided with each Hale SmartFOAM system to make
the flow sensor, control unit and motor controller con-
nections.
The system installer must supply primary power wire,
low tank level sensor wire and flat braided ground
straps.
CAUTION!
Review the “Safety” section of this manual in
its entirety before proceeding with electrical
connections.
❑
To prevent system damage or electrical shock the
main power supply wire must be the last connection
made to the Hale SmartFOAM motor controller.
❑
The cables provided with each Hale SmartFOAM
system contain shielded assemblies.
❑
NEVER attempt to shorten or lengthen the shielded
cables. If necessary order
❑
longer or shorter cables from Hale Products to suit
the particular installation.
❑
The cables are indexed so they connect to the cor-
rect receptacle one way only. When making cable
connections DO NOT force mismatched connections
as damage can result, causing improper system op-
eration.
❑
The cables shipped with each Hale SmartFOAM are
tested at the factory with that unit. Improper handling
and forcing connections can damage these cables
which could result in other system damage.
❑
The system can only perform when the electrical
connections are sound. Make sure each electrical
connection is correct.
❑
Hale SmartFOAM systems are designed for use on
direct current, negative (–) ground apparatus electri-
cal systems only.
❑
Do not mount radio transmitter or transmitter cables
in direct or close contact with the Hale SmartFOAM
unit.
❑
Before connecting the cables, inspect the O-ring
seal in the female connector. If the seal washer is
missing or damaged, water can enter the connector
causing corrosion of the pins and terminals resulting
in possible system failure.
❑
The ground strap must be a minimum of 1-1/4”
(32 mm) wide and no longer than 18” (457 mm).
❑
A longer ground strap must be wider or a double
thickness strap must be used. Make sure the ground
strap is attached to the chassis frame. Grounding to
the body IS NOT acceptable.
❑
Always disconnect the power cable, ground straps,
electrical wires and cables from the control unit or
other Hale SmartFOAM equipment before electric
arc welding at any point on the apparatus. Failure to
do so could result in a power surge through the unit
that could cause irreparable damage.
❑
There are no user serviceable parts inside Hale
SmartFOAM system electrical/ electronic compo-
nents. Opening of these components (distribution
box or controller unit) voids the warranty.
