Table 6: Recommended Primary Power Cable Sizes
Models 3.3 and 5.0 Maximum length
8 AWG (8.4mm 2 ) 6’ (1.8M) or less
4 AWG (21.2mm 2 ) 6; (1.8M) to 15” (4.6M)
0 AWG (53.5mm 2 ) 15’ (4.6M) or Longer
that power is supplied to the Hale Foam-Logix when
the main apparatus electrical system is energized
and the pump is in gear. Use of a solenoid with
a 150 AMP peak, 85 AMP continuous rating is
recommended. Figure 5: “Recommended Relay
Wiring Schematic” shows the recom mended wiring
for this relay.
Note: This ensures immediate operation when
the operator places the apparatus in PUMP mode,
and to prevent battery power drain when the
apparatus is not running.
With Hale FoamLogix 2.1A and 1.7AHP cable
lengths up to 6’ (1.8 meters) require a minimum 8
AWG type SGX (SAE J1127) battery cable. (See
Table 6: “Recommended Primary Power Cable
Sizes.”) Use solder lugs on cable ends with a 5/16”
(8mm) diameter hole.
When planning cable runs make sure the primary
wires are routed by the shortest most direct route.
A braided flat ground strap connected to the
apparatus chassis is recommended for the ground
connection.
This limits the RFI/EMI interference encoun tered
with radios, computers or other sensi tive electronic
equipment. The ground strap should be a minimum
of 1-1/4” (32mm) wide and no longer than 18”
(457mm). It must have soldered flat lug ends with
3/8” (10mm) diameter holes. If the ground strap
length exceeds 18” (457mm), a wider ground strap
should be used or use a double thickness of 1-1/4”
(32mm) wide ground strap. The ground strap must
be connected to the chassis. Use minimum 5/16” (8
mm) diam eter bolt or mounting to secure the strap.
Power and ground must also be provided for the
display unit using the 2 pin Packard connector. The
power must be a minimum 5 amp dedicated and
fused circuit. The ground must be connected to the
chassis ground stud and protected from corrosion.
Make sure the ground is attached directly to the
chassis frame and not to the apparatus body work.
IMPORTANT!
BEFORE MAKING GROUND CONNECTIONS REMOVE
ALL PAINT, GREASE AND COATINGS FROM THE
CONNECTION AREA. AFTER MAKING CONNECTION,
SEAL AGAINST CORROSION. WHEN A FLAT GROUND
STRAP IS NOT AVAIL ABLE USE A BATTERY CABLE
ONE SIZE LARGER THAN THE POWER CABLE USED.
FOAM CONCENTRATE TANK
A foam concentrate tank must be supplied to suit
the capacity required for the apparatus application.
The tank must meet NFPA minimum standards for
its design capacity, including:
❑
Filler size
❑
Vapor pressure venting
❑
Baffling
❑
Drain facilities.
