ELECTRICAL INSTALLATION
Electrical Connections
Complete harness electrical diagrams are provided
on page 45 of this manual. Refer to these diagrams
for proper installation of each of the electrical
components.
The Hale FoamLogix system is designed to be
installed with a minimum of electrical connections.
Cables are provided with each Hale FoamLogix
system to make the flow sensor, control unit and
motor controller box connections.
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,
beginning on page 11, 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 FoamLogix motor
controller box. See Figure 3: “Typical Hale
FoamLogix 2.1A and 1.7APH System Layout” on
page 21.
❑
The cables provided with each Hale FoamLogix
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
correct receptacle one way only. When making
cable connections DO NOT force mismatched
connections as damage can result, causing
improper system operation.
❑
The cables shipped with each Hale FoamLogix
system 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 FoamLogix systems are designed for use
on direct current, negative (–) ground apparatus
electrical systems only.
❑
Do not mount radio transmitter or transmitter
cables in direct or close contact with the Hale
FoamLogix 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”
(32mm) wide and no longer than 18” (457mm).
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 FoamLogix 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 FoamLogix system electrical/ electronic
components. Opening of these components
(motor controller box or control unit) voids the
warranty.
