GENERAL MAINTENANCE INSTRUCTIONS
The SCR control, like all electrical apparatus, does have some thermal losses. The semiconductor
junctions have finite temperature limits above which these devices may be damaged. For these rea-
sons, normal maintenance should guard against any action which will expose the components to
excessive heat, such as steam cleaning; or which will reduce heat dissipating ability of the control,
such as restricting air flow.
The following DOS and DONTS should be observed:
Any controls that will be used in ambients of 100 F (40 C) or over should be brought to the
attention of the truck manufacturer.
All external components having inductive coils must be filtered. Refer to vehicle manufac-
turer for specifications.
The control should not be steam cleaned. In dusty areas, use low-pressure air to blow off the
control. In oily or greasy areas, a mild solution of detergent or denatured alcohol can be used
to wash off the control and then blow completely dry with low-pressure air. The control can
also be cleaned with Freon TF degreaser.
For the SCR panel to be most effective, it must be mounted against the frame of the truck.
The truck frame, acting as an additional heat sink, will give improved truck performance by
keeping the SCR control package cooler. The use of a heat-transfer grease (Dow Corning
340) is recommended.
Terminal boards and other exposed SCR control parts should be kept free of dirt and paint
that might change the effective resistance between points.
CAUTION: The truck should not be plugged when the truck is jacked up and the drive
wheels are in a free wheeling position. The higher motor speeds can create excessive
voltages that can be harmful to the control.
Do not hipot (or megger) the control. Unless the terminals of each semiconductor and card
are connected together, the control may be damaged. Refer to control manufacturer before
hipotting.
Use a lead-acid battery with the voltage and ampere hour rating specified for the vehicle.
Follow normal battery maintenance procedures, recharging before 80 percent discharged and
with periodic equalizing charges.
