Electrical Connections
Follow the system electrical diagram (Figure 9-1) for
proper hookup of each of the electrical components.
Complete molded cable sets are provided with each
FoamPro system to make all the necessary
connections. The cables are color coded and “indexed”
so they can only go in one way.
DO NOT force
mismatched connections.
The system can only
perform when the electrical connections are sound, so
make sure each one is right.
Some Things to Keep in Mind
•
Do not hook up the main power cables until all
connections are made to each of the electrical
components. The last connection should be the
power cable to foam pump/motor base assemblies.
Warning: The electric motor-driven foam pump
contains a capacitor on the input power. Connect
leads with battery off or disconnected. Current will
flow even with the master circuit breaker off.
CAUTION: Never attempt to cut or lengthen the
molded cables. Doing so will result in RFI/EMI
interference. Contact the factory if molded cables of
a different length are required.
•
The FoamPro AccuMax SP requires two separate
electrical connections. The connection for the valve
driver box on the hydraulic-drive foam pump
requires 5 amps minimum. It is recommended to
install a 5 amp fuse to the + power line to the valve
driver.
• A 5 amp circuit breaker is provided on the valve
driver box for the hydraulic motor-driven foam pump.
•
This system is designed for use on 12-volt or 24-volt
negative ground systems only.
